Improving California’s
Forest and Watershed Management



Executive Summary

Forests Provide Critical Statewide Benefits, but Poor Conditions Put Those Benefits at Risk. Roughly one‑third of California is forested, including the majority of the watersheds that serve as the key originating water source for millions of people across the state. These forests also provide critical air, wildlife, climate, and recreational benefits. However, a combination of factors have resulted in poor conditions across these forests and watersheds, including excessive vegetation density and an overabundance of small trees and brush. Such conditions have contributed to more prevalent and severe wildfires and unprecedented tree mortality in recent years, and experts are concerned these trends will continue if steps are not taken to significantly improve the health of the state’s forests.

Recommendations. While broad consensus exists about both the problematic conditions of the state’s forests and the types of activities needed to address them, the pace of making the needed improvements is slow. Moreover, the scale of the improvement projects that are currently taking place is relatively small compared to the identified need. We make various recommendations to improve the health of the state’s forested watersheds. These recommendations encompass both larger actions as well as some more moderate steps that we believe could help achieve improved outcomes.

Improve and Increase Funding and Coordination.

  • Recognize the statewide benefits that healthy forests can provide by maintaining at least the current level of funding—$280 million annually—for projects to improve forest health.
  • Take steps to generate additional investments from downstream beneficiaries by (1) requiring the State Water Project to make an annual spending contribution to maintain the health of the Feather River watershed, (2) appropriating $2 million for pilot projects for local water and hydropower agencies to conduct wildfire cost‑avoidance and cost‑benefit studies, and (3) modifying grant criteria for the Integrated Regional Water Management program to encourage spending on watershed health projects.
  • Designate the California Natural Resources Agency (CNRA)—rather than the California Department of Forestry and Fire Protection (CalFire)—as the lead agency to oversee proactive forest and watershed health funding and initiatives.
  • Ensure that future spending is based on clear prioritization criteria that targets funds to maximize statewide benefits—such as reducing fire risk, protecting water supplies, and sequestering greenhouse gas emissions—in particular by promoting larger projects.

Revise Certain State Policies and Practices to Facilitate Forest Health Activities.

  • Allow the sale of timber without a timber management plan in specific cases when the primary purpose of the project is forest health in order to help offset the costs of beneficial forest thinning projects.
  • Direct CNRA to submit a report proposing options for how the state might streamline forest health project permitting requirements.

Improve Landowner Assistance Programs to Increase Effectiveness.

  • Allocate funding to CalFire for additional forester positions to increase the department’s use of prescribed fire through its Vegetation Management Program.
  • Restructure California Forest Improvement Program payments to reduce the burden on small landowners by providing partial payments in advance of work being undertaken.

Expand Options for Utilizing and Disposing of Woody Biomass.

  • Support the development and incentivize the use of nontraditional wood products by appropriating funding for a pilot grant program.
  • Increase opportunities for disposing of biomass by (1) requiring CalFire and the California Air Resources Board to analyze when burn permit requirements could be eased and (2) appropriating funding to purchase additional air curtain burners based on an analysis by CalFire.

Introduction

Roughly one‑third of California is forested, including the majority of the watersheds that serve as the key originating water source for millions of people across the state. These forests also provide critical air, wildlife, climate, and recreational benefits. However, a combination of factors have resulted in poor conditions across these forests and watersheds, including excessive vegetation density and an overabundance of small trees and brush. Such conditions have contributed to more prevalent and severe wildfires and unprecedented tree mortality in recent years, and experts are concerned these trends will continue if steps are not taken to significantly improve the health of the state’s forests.

This report consists of five sections. First, we review the importance of and benefits provided by California’s forests. Second, we provide information regarding how forests are managed in California, including ownership, state and federal policies and programs, and funding. Third, we review the current conditions of forests and watersheds across the state, including the concerning implications and recent consequences of those conditions, as well as the actions that would be needed to make improvements. Fourth, in the findings section, we highlight shortcomings in how the state manages its forests and watersheds. Fifth, we offer recommendations for actions the Legislature could take to improve forest and watershed management in California.

Why Forests Matter

Forests Provide Critical Statewide Benefits. Forests cover about one‑third of the state’s land area, containing over 4 billion live trees. (Land is considered forested if at least 10 percent of it is covered by tree canopy, or if it formerly had such tree cover and has not yet been formally developed for other uses.) While only a small percentage of the state’s population lives in forested areas, forests affect the lives of residents across the state. Figure 1 summarizes the specific statewide benefits provided by forests. Among the most important benefits is the role forests play in collecting and storing the snowpack that most Californians depend on for water. Additionally, by storing carbon, the state’s forests also play a vital part in helping the state to combat climate change and to meet its ambitious goals for reducing greenhouse gases (GHGs). The forest ecosystems and the diverse terrestrial, aquatic, and plant species that live in them represent a public resource belonging to and entrusted to all Californians. Forestlands also provide a variety of recreational opportunities, including in areas preserved, owned, and managed by public agencies for broad public access.

Figure 1 - California’s Forests Provide Critical Statewide Benefits

Most of State’s Key Watersheds Are Located in Forestlands. In a typical year, the majority of California’s total annual precipitation—in the form of rain and snow—falls in the mostly forested Sierra Nevada and southern Cascade mountain ranges. The rivers and streams flowing from these key “source watersheds” provide the crucial surface water that a majority of Californians use for drinking and most of the state’s agricultural sector uses for growing crops. Some estimates suggest that rain and snow that start in Sierra Nevada forests contribute around 60 percent of the state’s developed water supply (water that is captured in reservoirs and distributed to users across the state). Forested watersheds in other areas of the state are also key for local water supplies. For example, the San Bernardino and Cleveland National Forests receive 90 percent of the annual precipitation for the Santa Ana River watershed, from which runoff contributes to the water supplies for 6 million people in Orange, San Bernardino, and Riverside Counties.

By storing snow through the winter wet season then releasing it as melted runoff into streams and rivers through the spring and early summer, these forests provide a natural water infrastructure upon which the state has long depended. In a typical winter, mountain snowpack is a “natural reservoir” that ultimately provides one‑third of the water supplies the state’s cities and farms will use throughout the rest of the year. Forests—including the mountain meadows located within forestlands—also protect water quality by reducing erosion of sediments into streams and by filtering out pollutants from runoff.

Changing Climate Increases Importance of State’s Forests. Predictions for how climate change will affect California in the coming decades magnify the importance of the statewide value that forests can provide. For example, scientists predict that in future years, a greater share of the state’s annual precipitation will come as rain rather than as snow, and that warmer temperatures will cause snow to melt into runoff earlier in the season compared to historical trends. Downstream reservoirs, however, do not have the capacity to take on the winter water storage role that mountain snowpack has traditionally provided. This increases the importance of efforts to preserve the ability of the state’s forests to capture—and maintain at higher elevations, for as long as possible—the snowpack that the state does continue to receive in mountain forests and meadows. Preserving and potentially increasing the role that forests play in sequestering carbon and constraining GHG emissions are also becoming important components in the state’s efforts to slow the effects of climate change. Additionally, warming temperatures and the potential for more frequent and severe droughts may cause some areas in lower elevations to become too dry to support the current species of trees, converting those forests to shrublands. This potential loss of lower elevation forestlands magnifies the importance of preserving the remaining, higher elevation forests.

Forest Management

How Forests Are Owned, Used, and Managed in California

33 Million Acres of Forestland in California Owned by Combination of Entities. As shown in Figure 2, close to 60 percent (nearly 19 million acres) of forestlands in California are owned by the federal government, including by the U.S. Forest Service (USFS), Bureau of Land Management (BLM), and National Park Service. Private nonindustrial entities own about one‑quarter (8 million acres) acres of forestland. These include families, individuals, conservation and natural resource organizations, and Native American tribes. Industrial owners—primarily timber companies—own 14 percent (4.5 million acres) of forestland. State and local governments own a comparatively small share—only 3 percent (1 million acres) combined.

Figure 2 - Majority of Forestlands in California Owned by Federal Government

Figure 3 displays these forest ownership patterns across the state. In some areas, neighboring parcels are owned by a patchwork of different owners. In other areas of the state, a single owner—typically a federal agency—owns a large swath of contiguous land.

Figure 3 - Patchwork of Owners Across California Forestlands

Though Private Forestlands Often Used for Timber, Harvesting Has Declined Over Time. As indicated earlier, 39 percent of forestlands across the state are under private ownership—both nonindustrial and industrial. Nonindustrial forest owners are those that typically have less than 5,000 acres of forestland and do not own a processing mill. The majority of these private owners hold parcels smaller than 50 acres and do not typically engage in selling timber. In contrast, private industrial interests own forestlands for the purpose of growing, harvesting, and selling timber. Private lands have provided the majority of California’s timber since the 1940s.

Figure 4 shows the amount of timber harvested in California on both private and public lands over the past 60 years. While subject to annual variation, total timber harvesting in California has declined by over two‑thirds since the late 1950s. As shown in the figure, harvest rates have dropped from over 4.8 billion board feet in 1988—its recent peak—to about 900 million in 2009, when it was at its lowest in recent history—a decline of over 80 percent.

Figure 4 - Timber Harvesting in California Has Declined Significantly

These trends are due to a variety of factors, including changes in state and federal timber harvesting policies. For example, several federal laws were passed in the 1970s that shifted the USFS’s forest management objectives away from production forestry and more toward conservation and ecosystem management. Those laws included the National Environmental Policy Act (NEPA)—which requires federal agencies to evaluate any actions that could have a significant effect on the environment—and the Endangered Species Act—which prohibits federal agencies from carrying out actions that might adversely affect a species listed as threatened or endangered. Environmental protection policies have also contributed to declines in private harvests, along with other factors. More recently, the economic recession in the late 2000s sharply reduced demand for new housing construction, thereby also suppressing demand for timber. Since 2009, timber harvesting rates have picked up somewhat, but have not returned to earlier levels.

Forest Management Involves Proactive Activities. “Forest management” is generally defined as the process of planning and implementing practices for the stewardship and use of forests to meet specific environmental, economic, social, and cultural objectives. Activities forest managers employ include timber harvesting (typically for commercial purposes), vegetation thinning (clearing out small trees and brush, often through mechanical means or prescribed burns), and reforestation (planting new trees). Figure 5 describes specific activities that managers typically undertake to improve the health of forests. As discussed later, research has shown that these are the types of activities that are most effective at preserving and restoring the natural functions and processes of forests, and thereby maximizing the natural benefits that they can provide. Efforts to extinguish active wildfires are not generally considered to be forest management activities, as they are more responsive than proactive.

Figure 5 - Key Forest Management Activities to Preserve and Improve Forest Health

Many Management Activities Result in Need to Remove Lumber and Woody Biomass. Forest management activities often involve the removal of trees or brush, whether for commercial or noncommercial purposes. The primary product of commercial timber operations is lumber that can be sold for revenue. In addition, both commercial and noncommercial timber management activities such as mechanical thinning typically require utilization or disposal of “woody biomass” that is often not of a size or quality to be used in lumber production at traditional sawmills. This includes limbs, tops, needles, leaves, and other woody parts. In some cases, woody biomass can be used to produce other products, although processing complications and limited demand can complicate these efforts, as we discuss later. Excess forest material that is not utilized as lumber or some other product is often either burned or left to decompose in the forest. Because leaving the material can create a fire hazard, woody biomass waste is most commonly disposed of using open pile burning—accumulating vegetation left by forest management activities into manageable piles that are subsequently burned.

Multiple Entities Involved in Forest Management. The mix of forest ownership across the state means that a number of different entities are involved in managing forestland. Figure 6 identifies the federal and state agencies with major forest management responsibilities in California. As shown in the figure, within the federal government this includes the three agencies with the largest forestland holdings in the state. For the state, the Department of Forestry and Fire Protection (CalFire) is the lead agency tasked with helping to manage nonfederal forestlands and forest health initiatives, although the other agencies also have some significant responsibilities.

Figure 6

Major State and Federal Agencies Involved in Forest Management

Agency

Primary Responsibilities

Federal

U.S. Forest Service

Owns and manages about 15.5 million acres of forestland in California, including 18 National Forests. Oversees activities related to resource development (including timber harvesting, grazing, and energy production), land conservation (including preserving designated wilderness areas), and recreation. Manages and suppresses wildfires on federal lands. Conducts forestry research.

Bureau of Land Management

Owns and manages about 1.6 million acres of forestland in California, including overseeing activities related to resource development, land conservation, and recreation.

National Park Service

Owns and manages about 1.4 million acres of forestland in California, including preserving natural and cultural resources and facilitating public access.

State

Department of Forestry and Fire Protection (CalFire)

Prevents and suppresses fire on wildlands within “State Responsibility Areas” (which includes over 13 million acres of private and state‑owned forestland). Oversees enforcement of state timber harvesting policies on private lands. Manages 71,000 acres of state research forests and conducts forestry research.

Board of Forestry and Fire Protection

Serves as regulatory arm of CalFire. Develops state’s forest policies and regulations.

Natural Resources Agency

Oversees the Timber Regulation and Forest Restoration Program, including coordinating multi‑department reviews of Timber Harvest Plans and developing performance measures for how timber harvest policies are attaining the state’s ecological goals.

Sierra Nevada Conservancy

Allocates state grants for local forest projects in the Sierra Nevada region. Leads collaborative Watershed Improvement Program to restore forests and watersheds in the region.

Besides those agencies identified in the figure, certain other federal and state agencies are also involved in forest management activities, though typically to a lesser degree. For example, several regulatory agencies review and approve activities on forestlands through their permitting authority. These include the U.S. Fish and Wildlife Service, the California Department of Fish and Wildlife (DFW), the California Air Resources Board (CARB), and the state’s Regional Water Quality Review Boards. We also note that the Wildlife Conservation Board allocates state funding to protect, restore, and improve forestlands, and the California Conservation Corps undertakes conservation projects to improve forest health, including fuel reduction and planting trees. Additionally, in response to a recent outbreak of severe tree mortality across the state’s forests, the Governor issued an executive order that established a Tree Mortality Task Force comprised of state and federal agencies, local governments, utilities, and various stakeholders to coordinate emergency actions.

In addition to the federal and state governments, other entities that implement and influence forest management activities include local governments such as cities, counties, and special districts (like water agencies, resource conservation districts, and air districts). Landowners, funders of conservation projects, and concerned stakeholders are also involved in forest management decisions and in implementing forest projects. These can include local residents, Native American tribes, nongovernmental organizations, private timber companies, and electric utilities.

State Holds Some Management Responsibilities Over Privately Owned Forests. Although the state owns only a small share of forestlands, state law tasks CalFire with certain responsibilities on privately owned lands. Specifically, CalFire’s historic mission has been two‑fold: (1) the protection of commercial timber on all nonfederal lands from improper logging activities and (2) the protection of watersheds from wildland fire in lands identified as part of the “State Responsibility Area” (SRA). The SRA includes about 13.2 million acres of forestland across the state—most of the forest not owned by federal agencies. CalFire’s SRA responsibilities include (1) enforcing fire prevention measures such as checking that homes have the required “defensible space” clear of brush, (2) fire suppression and other emergency response activities, and (3) providing financial and technical forest management assistance to private landowners. Additionally, CalFire regulates timber harvest activities on both industrial and nonindustrial private lands by enforcing the state’s Forest Practice Rules and reviewing the timber harvest and forest management plans that we discuss later. The department also leads the state’s efforts to improve and maintain the health of forestlands in California, including by administering grant programs.

Partnerships Enable Entities to Work Across Ownership Boundaries. While forest management responsibilities typically align with ownership, natural processes—such as forest fires, water runoff, and wildlife habitats—do not observe those jurisdictional boundaries. As such, federal and state agencies have developed certain arrangements to collaborate on management activities across California’s forests. For example, federal law has a provision—known as the “Good Neighbor Authority”—that allows states to fund and implement forest health projects on federally owned land. As discussed later, the federal government also funds a number of grant programs to encourage collaborative projects on both federal and nonfederal forestlands. Additionally, federal and state agencies have established agreements for collaborative fire suppression efforts across jurisdictions when fires do occur.

State and Federal Forest Management Policies and Practices

Changing Emphasis on Fire Suppression Over Time. Well into the 19th century, suppression was not the standard response to wildfire in the rural, sparsely populated West. Naturally occurring fires typically burned their natural courses. However, as population density grew and forestlands were developed, wildfire began posing a greater risk to lives and property. When USFS was established in 1905, its primary task was to suppress all fires on the forest reserves it administered. By 1935, USFS fire management policy stipulated that all wildfires were to be suppressed by 10:00 in the morning after they were first spotted.

Similarly, the California Legislature first appropriated money for fire prevention and suppression work in 1919, and the Division of Forestry was created in 1927. Initially, the department provided rangers and lookout towers before fully taking on the responsibility to suppress fires in SRA in the 1940s. Currently, CalFire has the stated goal of containing 95 percent of all fires—excluding prescribed fires—at ten acres or less. These firefighting efforts have been highly successful, with the acreage burned by wildfires in California reduced from an estimated annual average of 4.5 million acres in the 1700s to about 1 million acres annually in more recent years. As forestlands have become more developed, firefighting resources have been increased to better protect homes and property, further reducing the number of acres burned annually.

USFS, however, has gradually shifted its policies back to allowing more fires to burn. The passage of the 1964 Wilderness Act encouraged allowing natural processes to occur, including fire. Accordingly, USFS has changed its policy from fire control to fire management, allowing fires to play their natural ecological roles as long as they can be contained safely based on weather patterns, terrain, proximity to development, and other factors. This policy includes both naturally caused fires and intentionally prescribed fires. This shift reflects a growing resurgence in the perspective that moderate fires can have beneficial effects on forestlands, such as clearing out smaller brush and stimulating natural processes like tree seed dispersal and replenishment of soil nutrients.

In contrast to USFS, CalFire has maintained its suppression goal, and generally still seeks to extinguish all naturally occurring fires. This is largely due to the nature of the areas the department is tasked with defending, which often are more developed than national forests.

State Forest Practice Rules Govern Timber Harvest on Privately Owned Forestlands. The state’s Z’Berg‑Nejedly Forest Practice Act of 1973 is the main California law that governs the management of California’s privately owned forestlands. The Forest Practice Act authorizes the state Board of Forestry and Fire Protection to develop regulations related to most commercial and noncommercial timber harvesting activities, known as the Forest Practice Rules (FPR). Under the FPR, landowners who wish to harvest and then sell their trees must submit and comply with an approved state‑issued timber harvesting permit.

The most common permit for the harvest and eventual sale of trees is a Timber Harvesting Plan (THP), which describes the scope, yield, harvesting methods, and mitigation measures that a timber harvester intends to perform within a specified geographical area over a period of five years. THPs are primarily utilized by larger industrial harvesters. The FPR also allow the use of other permits for harvesting and selling trees, such as a Nonindustrial Timber Management Plan (NTMP), which was added by the Legislature in 1991. NTMPs are intended to make it easier for small nonindustrial landowners—those who own less than 2,500 acres and are not primarily engaged in the manufacturing of forest products—to better manage their forests, including tree removal and sale of some relatively small amount of timber. NTMPs involve a longer‑term management plan better suited to the intended land uses than a THP. Additionally, the Working Forest Management Plan program—enacted through Chapter 648 of 2013 (AB 904, Chesbro)—allows for a long‑term forest management plan for nonindustrial landowners who wish to harvest and sell some of their trees and who own less than 15,000 acres of timberlands if the landowner commits to specific forest management practices. After a THP or other harvest management plan is prepared, staff from the state’s Timber Regulation and Forest Restoration Program (TRFRP) review it for compliance with state regulations designed to ensure sustainable harvesting practices and minimize environmental harms. The TRFRP was created by Chapter 289 of 2012 (AB 1492, Committee on Budget). The California Natural Resources Agency (CNRA) takes the lead role in conducting these reviews but gets assistance from CalFire, DFW, the Department of Conservation, and the State Water Resources Control Board (SWRCB). CalFire is tasked with enforcing the FPR and ensuring landowners comply with approved permits by conducting site inspections. If landowners or timber operators are found to be out of compliance with FPR requirements, CalFire is authorized to issue citations, fine violators, or shut down harvesting operations. As we discuss below, there are circumstances in which a permit is not required, such as for specified emergencies.

Over time, the Legislature has made changes to the Forest Practice Act and Rules in order to address various concerns and encourage certain management practices. For example, in 2012 AB 1492 created the TRFRP within CNRA and levied a 1 percent lumber assessment to fund the program. It also directed CNRA to develop ecological performance measures to evaluate the cumulative impacts of management and harvesting activities on a larger scale and support more long‑term goals for minimizing the environmental impacts of such activities, which could inform further modifications to the FPR going forward. The Legislature and Board of Forestry have also made changes to the FPR to address the effects of drought and tree mortality, modernize rules for the building and maintenance of logging roads, take into account the state’s GHG emission‑reduction goals, and promote oak woodlands restoration.

State and Federal Environmental Laws Regulate Forest Management Activities. While forest owners are responsible for managing their own lands, state and federal regulatory agencies are statutorily required to ensure that those management activities do not result in excessively negative environmental impacts. For example, an operation to remove trees for either commercial harvest or to improve the health of the forest could impact habitats for sensitive wildlife or create sediment runoff into a nearby stream and degrade water quality. To prevent such negative impacts, entities seeking to undertake activities to improve forest health typically must first receive approvals from specified agencies entrusted with safeguarding water, air, and wildlife resources on behalf of the public.

As discussed above, landowners seeking to harvest timber must complete THPs, which include assessments of potential environmental impacts and mitigation requirements. Entities seeking to conduct other types of forest management projects on nonfederal lands and/or projects that are funded with state dollars typically must attain other types of environmental permits. The major permits typically required for forest management projects are summarized in Figure 7. Generally, the most significant and comprehensive reviews are the Environmental Impact Reports (EIRs) required by the California Environmental Quality Act (CEQA). These reviews evaluate potential environmental impacts in a number of categories including biological resources, cultural resources, GHG emissions, and hydrology. Because THPs involve state department reviews of potential impacts on water quality and wildlife, traditional commercial timber harvesting projects covered by THPs typically do not require a CEQA review or additional state environmental permits.

CalFire = California Department of Forestry and Fire Protection.

Projects undertaken on federal lands typically require separate regulatory approvals from federal agencies. This frequently includes approval of an Environmental Impact Statement required by NEPA—which is similar to the state’s CEQA process—as well as federal permits to preserve water quality and wildlife species that have been identified as needing special protections. In general, state permits are not required for projects on federal lands unless they are being funded using state dollars.

Certain Forest Management Projects Can Qualify for Special Permits or Exemptions. Although many forest management projects on nonfederal lands require the types of permits described in Figure 7, certain types of projects qualify for more streamlined regulatory approvals. For example, some projects may be covered by “programmatic” EIRs for which CalFire has undertaken a large‑scale CEQA review. These programmatic EIRs analyze the potential impacts of a series of similar forest health activities—essentially treating them as one large, ongoing project and creating a broad permit that allows similar activities to be implemented over time without undertaking additional environmental reviews. For instance, CalFire has approved a programmatic EIR—known as a Program Timberland EIR—to cover a handful of similar projects on nonfederal forestlands in Northern California that combine wildfire reduction with timber harvest. The department is also in the process of developing a programmatic EIR for its Vegetation Management Program (VMP), which would allow it to undertake certain types of prescribed burning, thinning, and restoration projects on nonfederal lands across the state without needing to conduct a new CEQA EIR analysis each time.

Other agencies, such as Regional Water Quality Control Boards, also have developed some special initiatives to expedite the permitting processes for forest management projects in certain instances. For example, the North Coast regional board issued a programmatic permit authorizing limited discharges into waterbodies for landowners in Mendocino County who implement specified types of restoration and conservation projects that may result in some sediment runoff while the projects are being implemented. In addition, the Central Valley and Lahontan regional boards are working together to develop a programmatic permit to regulate “nonpoint source pollution” that would authorize certain activities on USFS and BLM lands, including specified types of timber harvesting and vegetation management projects. These programmatic permits replace the requirement that landowners attain project‑specific permits, but include oversight and monitoring to ensure agreed‑upon practices and mitigation are employed.

Additionally, the Legislature has instituted several statutory CEQA exemptions for particular forest management activities, meaning no CEQA review is required. These include removal of dead trees and removal of invasive species.

Forest Carbon Plan Provides Framework for Management to Increase Sequestration and Minimize GHG Emissions. The state has undertaken a multifaceted effort to reduce GHG emissions and sequester carbon. This includes the cap‑and‑trade program, which involves the auctioning of permits that allow businesses to emit GHGs, with the resulting revenue deposited in the Greenhouse Gas Reduction Fund (GGRF). Another component of the state’s GHG reduction strategy is the state’s Forest Carbon Plan, which will serve as a blueprint for how the state can manage forests in order for them to reduce GHGs. It is being prepared by CalFire, CNRA, and CARB, with a draft version published in 2017 and a final version expected in 2018. The plan examines California’s various forestry needs and available treatment activities with the goal of increasing GHG sequestration by improving forest health and reducing GHG emissions by minimizing wildfire severity. It also examines strategies to prevent forestland conversions and innovate opportunities for wood products and biomass utilization.

State Programs and Funding for Forest Management

Estimates Suggest Current Spending for Forest Health Is Treating About 280,000 Acres Per Year. Estimates of the level of current forest health activities being undertaken across the state vary, particularly because a large proportion of forests are owned and managed by private entities. USFS has a stated goal of implementing fuel reduction treatments on 500,000 acres of its lands in California each year; however, the need to internally redirect resources from restoration to fire suppression has resulted in a lower rate of restoration. Instead, USFS has treated an average of about 250,000 acres per year in recent years. Specifically, in 2017 USFS treated 140,000 acres through thinning and prescribed fire and an additional 110,000 acres through managed natural fires. According to the draft Forest Carbon Plan, BLM treats about 9,000 acres of its forestlands annually. The plan also states that CalFire treats about 17,500 acres of SRA land per year through its VMP, which is discussed in greater detail below. Estimates are not readily available for how many acres of forestlands private landowners treat on their own each year. A recent report by the Public Policy Institute of California estimates that ongoing federal and state funding for proactive forest management in California has averaged around $100 million annually in recent years. In this section, we describe how these funds have been spent.

State Funds Several Programs to Promote Forest Health. The state funds programs in several different state departments that are intended to encourage activities that support California’s forests, including to reduce wildfire risk. Many of these programs are designed to assist private landowners in effectively managing their lands, given they own a significant portion of the state’s forests. Figure 8 summarizes the state’s major forest management programs and the funding that was provided in 2017‑18. As shown, as the state’s lead entity for addressing forest health, CalFire administers most of these programs. We discuss several of these programs in more detail below.

State’s Largest Forest Health Program Currently Funded With GGRF. The 2017‑18 budget package provided a significant one‑time infusion of funding for forest management from the state’s GGRF. Specifically, as shown in Figure 8, $200 million was allocated to CalFire for forest health and fire prevention activities that either reduce GHG emissions through wildfire avoidance, or improve carbon sequestration by preserving forestland or improving forest health. (CalFire also received one‑time allocations from GGRF for forest health in previous years but at lesser levels—$25 million in 2014‑15 and $40 million in 2016‑17.) CalFire plans to allocate these funds via grants for projects through its Forest Health Program. Local entities and collaboratives—such as the Sierra Nevada Watershed Improvement Program, described in the nearby box—will be eligible to apply for these funds. Based on the grant criteria CalFire has developed, eligible projects must show that they will reduce GHGs, be located in a priority region (such as an area with elevated tree mortality or wildfire threats), and result in co‑benefits (such as improved air quality improvement or conservation of wildlife habitat). The Governor’s budget proposal for 2018‑19 proposes an additional $160 million from GGRF to CalFire for this program.

Sierra Nevada Watershed Improvement Program

The Sierra Nevada Watershed Improvement Program (WIP) was created in March 2015 as a coordinated effort between the state (through the Sierra Nevada Conservancy) and the U.S. Forest Service, along with other governmental and local agency partners. It is intended to increase the pace and scale of restoration and forest health activities within several key California watersheds. The program is formalized through a memorandum of understanding between the state and federal governments, which is designed to increase coordination of restoration efforts at the regional and watershed levels. Both the extent of land area that is covered and the number of agencies proactively working together make this collaborative effort unique.

The WIP has three main goals for the Sierra Nevada region: (1) increase investment in forest restoration from a broad array of stakeholders, (2) identify policy‑related issues that need to be addressed in order to restore Sierra forests and watersheds to a healthier state, and (3) maintain and expand existing forest‑related infrastructure—such as lumber mills and other facilities that process or dispose of wood and woody biomass—in order to support the pace and scale of needed restoration. Currently, WIP partners are working to assess restoration needs and secure funding. The program has identified a subregion in which to conduct initial pilot projects that accelerate regional scale forest and watershed restoration, which it is calling the Tahoe‑Central Sierra Initiative. It recently received a $5 million grant from the California Department of Forestry and Fire Protection’s Greenhouse Gas Reduction Fund Forest Health Program to begin implementing forest health projects in this subregion.

California Forest Improvement Program (CFIP) Helps Smaller Landowners Maintain Their Forestlands. CFIP assists private nonindustrial landowners manage their forestlands. Specifically, the program offers grants to help individual landowners with land management planning, land conservation practices, fish and wildlife habitat improvement, tree purchase and planting, and practices to enhance the productivity of the land. As shown in Figure 8, this program has received $5 million from the Timber Regulation and Forest Restoration Fund (TRFRF) in 2017‑18. (In some recent years, it has also received funding from the High‑Speed Rail Authority for mitigation related to the state’s high‑speed rail project.) The state typically pays 75 percent of the overall costs of the project, but is authorized to pay up to 90 percent if the project meets certain criteria (such as responding to substantial fire damage). The CFIP is structured such that landowners apply for funding, receive an approved agreement and scope of work from CalFire, then undertake planning and/or complete the work on their land. Once work is completed, CFIP reimburses landowners for a share of the costs. The state also conducts oversight during and after the projects. For example, participants must agree to keep land in a “compatible use” (that is, in a forested state) for at least ten years after work is completed, and the state monitors that this agreement is kept. While the number varies each year based on funding levels and the specific projects undertaken, the program funded 183 projects statewide over the past two years.

VMP Is State’s Main Forest Program for Prescribed Fire. Prescribed fire—employed under appropriate conditions—is an important restoration tool that improves forest resiliency and reduces the risk of large, high‑intensity fires. It is also generally more cost‑effective than mechanical thinning and can reach remote areas of the forests where equipment cannot go. Most prescribed burns occur under CalFire’s VMP—the state’s main prescribed burn program. The VMP provides a cost‑sharing option for landowners to assist with the use of prescribed fire. The program also funds some mechanical thinning projects, though prescribed fire is its primary focus. The specific cost‑share ratio varies based on the share of public‑to‑private benefit, as determined by CalFire. Eligible applicants must treat forestland located within the SRA. Landowners apply to participate in the VMP, and CalFire determines whether a project is suitable for funding. The local CalFire unit then provides the personnel, equipment, and expertise to implement the project, and the department assumes the liability for conducting the prescribed burn. As shown in Figure 8, in 2017‑18 the program received about $10 million from the General Fund.

The VMP treated 17,500 acres with prescribed burns in 2017, somewhat more than the average of approximately 13,000 acres treated per year since 1999. This represents a decrease from about 30,000 acres treated per year from 1982 through 1998. This decrease is due to several factors, including (1) an increase in the amount of planning and documentation required for prescribed burns due to stricter air quality regulations, (2) projects more often being in close proximity to populated areas, and (3) longer fire seasons that can divert CalFire foresters and firefighters who would be available to plan and implement prescribed burn projects.

State Funding for Forest Health Activities Comes From Various Sources. As shown in Figure 8, most of the support for the state’s forest health programs comes from GGRF, the General Fund, or TRFRF. TRFRF, which was created by AB 1492 in 2012, is funded by an assessment on lumber that generates about $40 million annually. The Forest Resources Improvement Fund supports the eight demonstration forests CalFire operates to test and disseminate sustainable practices. That fund receives revenues generated by sales of timber or biomass fuels from those demonstration forests.

In addition to the programs displayed in Figure 8, the state has provided other one‑time resources for special initiatives related to forest and watershed health. For example, in 2017‑18 the Legislature provided roughly $10 million from the General Fund to CalFire and the Office of Emergency Services for one‑time grant programs to address the recent increase in tree mortality, including to support local efforts to remove dead and dying trees that pose a threat to public health and safety. The state has also traditionally relied on funding from voter‑approved resource bonds for some forest and watershed health initiatives. For example, Proposition 84 (2006) set aside $180 million for the Wildlife Conservation Board to implement a program to conserve and restore forestlands, including by acquiring conservation easements. Proposition 1, passed by voters in 2014, included $1.5 billion for various watershed protection and restoration efforts, many of which may be implemented in forestlands.

Additionally, the Legislature recently passed legislation, Chapter 852 of 2017 (SB 5, de León), which places a new general obligation bond—Proposition 68—on the June 2018 ballot for voter approval. This bond would provide roughly $170 million across various state agencies that could be directed towards improving forest and upper watershed health. That total includes $35 million for CalFire to improve forest resiliency, of which at least $25 million must be allocated to the Sierra Nevada Conservancy for the Sierra Nevada Watershed Improvement Program described earlier.

Significantly More CalFire Spending Dedicated to Fire Response Than Proactive Management. Figure 9 shows CalFire’s two major expenditure categories over the past two decades—fire response and forest management. As shown, spending for suppressing fires has far eclipsed that for proactive forest management activities. Specifically, fire response spending, which grew from $650 million in 1998‑99 (adjusted for inflation) to more than $2.3 billion in 2017‑18, makes up over 90 percent of the department’s annual spending. In contrast, spending on proactive activities like resource management and fire prevention remained relatively flat over the period, averaging $77 million and 7 percent of the department’s total expenditures through 2013‑14. Beginning in 2014‑15, the department began receiving some one‑time increases from GGRF for forest health activities. As shown, the significant addition of GGRF in 2017‑18 notably increases resource management spending compared to historical levels.

Figure 9 - Significantly More CalFire Spending on Fire Response Than Proactive Management

The data shown in the figure, however, may somewhat understate fire response and overstate resource management spending. This is because CalFire redirects internal staff resources to help respond to fire emergencies when needed. For example, when fire crews are needed for emergency fire suppression during the limited time of year they might otherwise be able to implement prescribed fires—such as during the fall and winter of 2017 when they were fighting the wine country and Southern California wildfires—it reduces the number of acres CalFire staff can treat with prescribed burns. Moreover, the number of severe fires and extended fire season to which CalFire has had to respond in recent years has necessarily placed the department in a recurring state of emergency response, as compared to previous years when it could more reliably count on an “off season” during which it could turn its focus to proactive fire prevention activities. On the other hand, the impacts of redirecting some resources are not as severe as those experienced by USFS—as discussed below—because CalFire is able to access additional resources to respond to emergencies.

Some Federal Funding Also Supports Forest Health Activities. In addition to state monies, the federal government also funds some forest management and health efforts. Besides managing the national forest system, the USFS operates its State and Private Forestry programs, which offer assistance to the state and private landowners for activities including forest health, cooperative forestry, conservation education, and urban and community forestry. The programs offer technical assistance, financial assistance, monitoring of forest health and sustainability, and educational and awareness campaigns. The 2017 federal budget provided $234 million for State and Private Forestry programs nationally. Additionally, the USFS Collaborative Forest Landscape Restoration Program, which received a total of $40 million in federal fiscal year 2017, provides grants for larger scale forest health projects on USFS lands conducted and funded in partnership with nonfederal partners. Based on grants from prior years, a share of these federal funds likely will be allocated to projects in California. The federal government also administers the Natural Resources Conservation Service, which provides significant support for private landowners. Finally, the U.S. Department of Agriculture’s Rural Development Program has provided one‑time grant assistance to communities in the Sierra Nevada to develop collaborative biomass projects.

Large Share of Federal Forest Management Funding Has Been Redirected to Fight Fires. One key funding issue with the federal government’s forest management approach is “wildfire borrowing.” Currently, when fire suppression costs exceed the amount Congress has appropriated, USFS pays for these excess costs out of its other budget categories, including restoration. Unlike CalFire, USFS does not have access to emergency funds for large fires. For the federal fiscal year that ended in fall 2015, USFS redirected $700 million—about one‑quarter of its forest management budget—to cover fire suppression costs. This redirected money from other programs including recreation, research, watershed protection, rangeland management, and forest restoration. For example, the State and Private Forestry programs—the primary federal effort to provide technical and financial assistance to protect communities from wildfire—lost $37 million out of a total budgeted amount of $234 million that instead went to cover fire suppression costs across the nation. This practice of redirecting funds from other USFS activities contrasts with how the federal government pays for the response to other natural disasters, such as floods or storms. In those cases, the federal government typically provides additional funding to cover excess federal emergency response costs, rather than expecting those funds to be redirected from the portions of the affected department’s base budget that would otherwise be used for prevention and maintenance activities.

Local Governments Also Spend Money on Forest Health Activities. Counties, cities, special districts, and other local governments also invest in forest health activities within their respective jurisdictions. Examples include Community Wildfire Protection Plans, which some communities develop to identify forest fuel reduction priorities and other preventative measures. These plans are particularly common and encouraged by the federal and state governments in communities located adjacent to forestlands. Some limited examples also exist of mountain regions opting to undertake forest restoration projects intended to preserve local water quality, and using local dollars to match state bond funds from the Integrated Regional Water Management (IRWM) program. (The IRWM program provides bond funding—which must be paired with local funds—for regional groups to implement locally determined water resource projects.) For example, the Madera County IRWM group paired $1.5 million in local funds with an equal amount of state bond funds to reduce fuels in the Sierra National Forest in order to reduce wildfire risk and, in the words of its IRWM grant application, to help “meet long‑term water supply needs, [protect] water quality, and augment/restore environmental conditions.” Investments by local agencies and governments in discretionary forest management programs can be significantly limited in many rural forested areas of the state, however, due to small tax bases and—in many cases—economically disadvantaged populations.

Current Forest Conditions

Healthy Forests Display Natural Ecological Characteristics and Processes. In general, a forest is defined as being healthy when it reflects the natural variability, processes, and resilience it has historically displayed. Specifically, conditions in healthy forests typically include (1) a heterogeneous mix of tree species of different ages; (2) a density of vegetation that matches the supply and demand of light, water, nutrients, and growing space; and (3) a capacity to tolerate and recover from naturally occurring disturbances such as fire, insects, and disease. The majority of California’s forests currently do not meet these health criteria.

In this section, we discuss the poor conditions of forestlands across the state and the associated risks and implications, including increased incidence of major wildfires. We also discuss how expanding forest health activities could improve these conditions and the multiple benefits such improvements could yield.

Poor Forest Conditions

Forest Management Practices Have Increased Forest Density. As noted above, forest management practices and policies over the past several decades have (1) imposed limitations on timber harvesting, (2) emphasized fire suppression, and (3) instituted a number of environmental permitting requirements. These practices and policies have combined to constrain the amount of trees and other growth removed from the forest. This has significantly increased the density of trees in forests across the state, and particularly the prevalence of smaller trees and brush. Overall tree density in the state’s forested regions increased by 30 percent between the 1930s and the 2000s. These changes have also contributed to changing the relative composition of trees within the forest such that they now have considerably more small trees and comparatively fewer large trees. Figure 10 illustrates some key differences between healthy and overly dense forests. The increase in tree density can have a number of concerning implications for California’s forests—including increased mortality caused by severe wildfires and disease—as displayed in the figure and discussed below.

Figure 10 - Comparing the Potential Impacts of Unhealthy and Healthy Forests

Increased Risk of Severe Forest Fires. Dense forest stands that are proliferated with small trees and shrubs contain masses of combustible fuel within close proximity, and therefore can facilitate the spread of wildfires. Moreover, these smaller trees can serve as “ladder fuels” that carry wildfire up into the crowns of taller trees that might have otherwise been out of reach, adding to a fire’s potential spread and intensity. As shown in Figure 11, CalFire estimates that most forested regions of the state face a high to extreme threat of wildfires. CalFire estimates the level of threat based on a combination of anticipated likelihood and severity of a fire occurring. Large and intense fires can have widespread negative consequences, as discussed below in the context of recent California wildfires.

Figure 11 - Many Areas of the State Face Fire Risk

Less Resilient Forests, Large Numbers of Dead Trees. In addition to increasing fire risk, overcrowded forests and the associated competition for resources can also make forests less resilient to withstanding other stressors. For example, trees in dense stands become more vulnerable to disease—including infestations of pests such as bark beetles—and less able to endure water shortages from drought conditions. This vulnerability has been on display in recent years, as an estimated 129 million trees in California’s forests died between 2010 and 2017, including over 62 million dying in 2016 alone. While this is a relatively small share of the over 4 billion trees in the state, historically, about 1 million of California’s trees would die in a typical year. Moreover, most of the die‑off is occurring in concentrated areas. For example, the Sierra National Forest has lost nearly 32 million trees, representing an overall mortality rate of between 55 percent and 60 percent. When dead trees fall to the ground they add more dry combustible fuel for fires, as well as pose risks to public safety when they fall onto buildings, roads, and power lines.

Loss of Carbon Sequestration Benefits, Potential Increase in Emissions. Another implication of the deteriorating conditions of the state’s forests relates to how they exacerbate climate change. Live trees absorb and store carbon dioxide, thereby reducing the amount of carbon dioxide in the atmosphere. In this way, healthy forests can be an important tool in offsetting climate change. Large older trees, however, store and sequester significantly more carbon than small trees and brush. As such, the dense conditions of the state’s forests—in which small trees are overcrowding and inhibiting the growth of larger, older trees—represent a lost opportunity to sequester GHG. Moreover, dead trees and wildfires release a large amount of carbon into the atmosphere at once, thereby contributing to climate change. According to the state’s draft Forest Carbon Plan, “forested lands in the state are the largest land‑based carbon sink, but recent trends and long‑term evidence suggest that these lands will become a source of overall net GHG emissions if actions are not taken to protect these lands and enhance their potential to sequester carbon.” CARB and climate researchers are currently attempting to quantify these GHG effects, to help the state better understand the potential carbon‑related benefits and risks associated with forests and wildfires.

Threats to Water Supply and Quality, Hydropower Generation. Scientists have identified several ways in which forest density can reduce the amount of water that runs off from source watersheds into rivers and streams for downstream uses. For example, if the forest canopy is too thick, snow will collect on the tops of the trees and be exposed to direct sunlight, causing it to more quickly evaporate rather than collecting on the ground and slowly melting into runoff. A greater volume of trees also means more water may be lost to evapotranspiration—consumption by the trees in order to grow—also leaving less available for runoff. Additionally, mountain meadows that have become overgrown with trees are less able to play their traditional role of “sponges” that store and gradually release snow and water.

Poor forest conditions can also affect water supplies when they contribute to severe fires. After such fires, burned and denuded hillsides are prone to discharging large amounts of sedimentation into streams, rivers, and reservoirs during storms. Downstream, these sediments can affect both water quality (by introducing soils, nutrients, and pollutants into water sources) and water supply (by displacing capacity in reservoirs). Excessive sedimentation in rivers and reservoirs can also impair the ability to generate hydropower when it clogs intakes, turbines, and other components of hydroelectric facilities.

The risk of wildfires also threatens the system that supplies water for millions of downstream water users. Of particular concern for millions of Californians is the risk to the Feather River watershed, which drains into Oroville Lake—the primary water source for the State Water Project (SWP). The SWP, which is operated by the state’s Department of Water Resources (DWR), is a water storage and delivery system that transports water from Northern California to supply 25 million people—two‑thirds of the state’s population—living across the state, as well as 750,000 acres of irrigated farmland mostly in the Central Valley.

The high potential for a fire is also a threat for the Central Valley Project (CVP), a separate water storage and delivery system owned and operated by the federal government. The CVP collects mountain runoff into reservoirs and then delivers it through canals to irrigate about one‑third of all agricultural land in the state, as well as to provide municipal water for close to 1 million households. Fires affecting any of the multiple Cascade and Sierra Nevada watersheds whose runoff feeds reservoirs for the CVP water delivery system would have major implications—in particular for the Pit and McCloud watersheds, which drain into Shasta Lake.

Increased Incidence of Major Wildfires

Poor Forest Conditions Have Contributed to Significant Wildfires in Recent Years. Recent events have revealed that the risk created by poor forest conditions has begun to manifest in increasingly frequent and severe wildfires. Figure 12 shows the 20 largest fires (as measured by acres burned) and 20 most destructive fires (as measured by number of structures destroyed) in recorded state history. As shown, the majority of such fires have taken place within the past 20 years. While the overall acreage of fires burned across the state’s forests varies from year to year, the figure shows that the acreage burned by individual fires has been on an upward trend, highlighting an increasing incidence of severe fires. Additionally, while it is to be expected that fire risk and impacts would increase over the past several decades as human development spreads into areas that formerly were wilderness—creating more opportunities for destruction—the extent of the increase in recent years is significant. Of particular note, both the largest and the most destructive fires the state has ever experienced occurred in 2017—the Thomas fire in December, which burned nearly 282,000 acres, and the Tubbs fire in October, which destroyed 5,643 structures and significant portions of the city of Santa Rosa. Such severe fires can have negative effects on a number of different sectors, as illustrated by the examples discussed in the nearby box.

Figure 12 - Most of the State's 20 Largest and 20 Most Destructive Fires Have Occurred in the Past Two Decades

Recent Fires Have Had Wide‑Reaching Negative Impacts

Examples of how recent fires have impacted various sectors include the following:

Property. Property losses from the October 2017 “wine country” fires in Sonoma, Napa, Solano, Lake, and Mendocino Counties—which included the Tubbs Fire—are expected to add up to between $6 billion and $8 billion. According to the California Department of Insurance, more than 14,000 homes were damaged or totally destroyed, along with nearly 4,000 commercial buildings, 3,200 cars, and 111 boats. These totals understate the total damage, as they do not include uninsured properties or vehicles.

State Costs. The state annually spends significant amounts on wildfire response and recovery. In the past ten years, the state has spent nearly $10 billion from the General Fund for the California Department of Forestry and Fire Protection’s wildfire response activities. Recovery costs for debris removal and cleanup, social services (such as shelters and social services), and local assistance (including rebuilding public infrastructure and backfilling property tax losses) can also be significant. For example, the administration estimates that state expenditures on wildfire and recovery activities for the 2017 wine country fires have totaled about $1.5 billion. While costs associated with these fires are eligible for federal reimbursement, the administration estimates that the state General Fund share of these costs will be roughly $400 million.

Air Quality. Smoke from the multiple wildfires that burned in the northern part of the state in October 2017 affected air quality and closed schools, airports, and businesses in cities at least 100 miles away from the fires. At its worst, fine particulate matter air pollution in San Francisco—located over 40 miles away from the fires—was measured at 190 micrograms per cubic meter, more than five times the federal health standard of 35 micrograms per cubic meter.

Greenhouse Gas (GHG) Emissions. The Sierra Nevada Conservancy estimates that the 2013 Rim Fire—the fourth largest in California history—released 11.4 metric tons of GHG emissions, equivalent to what 2.6 million cars would release in a year. Moreover, burned trees left on the landscape will continue to release additional emissions as they decay over time.

Water Supply and Quality. Initial estimates suggest the 2012 Bagley Fire resulted in an estimated 330,000 metric tons of fine sediment and 170,000 metric tons of sand, gravel, and cobbles deposited into Lake Shasta—which stores drinking and agricultural water supplies for millions of customers.

Habitat for Fish and Wildlife. One study found that the 2013 King Fire destroyed 30 out of 45 known habitat sites in the El Dorado National Forest for the California Spotted Owl, and that those sites remained unsuitable even a year after the fire.

Improving Forest Conditions

Consensus That Suite of Activities Needed to Improve Conditions. As described earlier, forest managers can undertake several types of activities or treatments to reduce forest density and improve the benefits that forests naturally provide. These include mechanical thinning, prescribed burning, managed wildfire, stream and meadow restoration, and land preservation. Most forest experts agree that, given the diversity of the state’s forests and extent of degraded conditions, managers should implement a combination of such activities across the state. Not every treatment can or should be employed in every situation. For example, steep and remote forested hillsides that lack road access are not practical locations for mechanical thinning operations. Additionally, in some cases treatment approaches might be most effective when used in combination. For example, applying prescribed fire to areas that currently contain large amounts of ladder fuels may not be safe until after they have been mechanically thinned because of the greater risk that a fire might escape control. Post‑thinning, however, prescribed fire can be a good way to restrain regrowth of “surface fuels” (small trees and brush) and stimulate natural processes.

Improved Forest Health Could Yield Multiple Benefits. As discussed earlier, forests provide multiple statewide benefits. Taking additional steps to improve the health of the state’s forests could restore, protect, and potentially magnify these key functions. Specifically, research indicates that thinning and restoring forests across the state potentially could lead to increased forest resilience against pests and disease, additional carbon storage, and potentially an increase in snowmelt runoff and water supply. Moreover, while fully preventing forest fires is impossible—given inevitable lightning strikes and widespread human interactions—reducing the amount of fuels in the forest could significantly reduce the size and severity of the fires that will eventually occur. For example, modeling of different fire scenarios in the Mokelumne watershed estimated that fuel treatments likely would reduce fire size by an average of roughly 40 percent, and reduce the acreage of a high‑intensity wildfire by approximately 75 percent. (Please see the box below for additional discussion of this study.)

Analysis of Mokelumne Watershed Finds Forest Treatments Yield Economic Benefits

In 2014, the Sierra Nevada Conservancy, U.S. Forest Service, and The Nature Conservancy published an analysis of how wildfire might affect resources in the Mokelumne River watershed under various hypothetical conditions. The report, Mokelumne Watershed Avoided Cost Analysis: Why Sierra Fuel Treatments Make Economic Sense, simulated the outcomes of five potential fire scenarios with and without the application of fuel treatment projects such as forest thinning and prescribed burning. The analysis found that fuel treatments would significantly reduce the size and severity of wildfires, and that the economic benefits of the modeled fuel treatments were two to three times the costs of their implementation. Specifically, the report estimated that while undertaking fuel reduction projects in the watershed would cost nearly $70 million, avoided costs from a severe wildfire (such as structures saved and avoided fire clean‑up) as well as potential revenue from the thinning activities (such as from merchantable timber, carbon sequestration, and biomass that could be used for energy or other purposes) could yield benefits of between $126 million and $224 million. The analysis found these economic benefits would accrue to both public and private entities, including the state and federal governments, residential property owners, timber companies, and water and electric utilities.

Forest Treatments Not Without Trade‑Offs. While forest management activities can help improve overall forest health, reduce fire risk, and potentially yield other benefits, their implementation can also have other, less desirable consequences. For example, in some cases removing trees can reduce available habitat for certain wildlife. Similarly, roads and heavy equipment necessary for mechanical thinning operations can both disrupt habitat for terrestrial species, as well degrade conditions for fish and aquatic species by increasing sediment runoff into streams. Prescribed and managed burns have been among the most controversial types of treatments because of the potential for the resulting smoke to temporarily degrade air quality in surrounding communities. Forest managers generally try to minimize and mitigate for these types of negative impacts, for example by leaving certain stands of trees in place for wildlife habitat, or by applying prescribed burns only under specific conditions that minimize public health impacts. The regulatory permitting processes described earlier help ensure these types of mitigations are implemented. On the whole, forest managers and the public must weigh the potential negative impacts of undertaking forest health activities against the potential benefits of applying the treatments—and against the risks inherent in not taking actions to improve forest and watershed health.

Findings

While broad consensus exists about both the problematic conditions of the state’s forests and the types of activities needed to address them, the pace of making the needed improvements is slow. Moreover, the scale of the improvement projects that are currently taking place is relatively small compared to the identified need. In this section, we identify and discuss some of the barriers that impede major progress towards healthier forests. We organize our findings into four categories: (1) funding and coordination, (2) policies and practices, (3) local assistance programs, and (4) disposal of woody biomass. Figure 13 summarizes our key findings.

Funding and Coordination Not Adequately Addressing Forest Conditions

Large Identified Costs to Improve Forest Conditions, State Spending Not Keeping Pace. As discussed earlier, ongoing state and federal funding for proactive forest management in California has averaged around $100 million annually in recent years, treating an estimated 280,000 acres per year. This level of treatment has not been sufficient to maintain healthy natural forest conditions, and a backlog of needed activity has formed and continues to grow. Experts suggest significant additional funding would be needed to increase the pace and scale of treatment activities such that they meaningfully improve current forest conditions. While no conclusive, comprehensive assessment of needs and costs has been completed, recent estimates for certain regions include the following:

  • Restoration on Nonfederal Lands. The draft Forest Carbon Plan states that 20 million acres of forestland in California face high wildfire threat and may benefit from fuels reduction treatment. According to the plan, CalFire estimates that to address identified forest health and resiliency needs on nonfederal lands, the rate of treatment would need to be increased from the recent average of 17,500 acres per year to approximately 500,000 acres per year. The plan does not include associated cost estimates.
  • Restoration on Federal Lands. Based on its ecological restoration implementation plan, USFS estimates that 9 million acres of national forest system lands in California would benefit from treatment. The draft Forest Carbon Plan sets a 2020 goal of increasing the pace of treatments on USFS lands from the current average of 250,000 acres to 500,000 acres annually, and on BLM lands from 9,000 acres to between 10,000 and 15,000 acres annually.
  • Restoration in the Sierra Nevada Region. A recent Public Policy Institute of California study cited estimated forest treatment needs of between 90,000 and 400,000 acres annually in Sierra Nevada forests to bring them back to historical conditions and functions. The authors found that the associated costs of mechanical thinning could vary widely—from net costs of around $800 per acre to net revenues of nearly $1,900 per acre—depending on the size of the trees removed and their potential sale value. This significant range results from the degree to which the thinning project primarily produces non‑revenue generating woody biomass, as compared to producing large trees that can be sold as timber. The report also cited a wide range of costs for applying prescribed fire—from $75 to $647 per acre—depending on the landscape where it is applied.
  • Restoration to Increase Water Supply. A nonprofit organization, The Nature Conservancy, published a study suggesting that healthier forests could increase streamflow runoff for Sierra Nevada watersheds by up to 6 percent, but that such results would require the current scale of forest restoration in those watersheds to increase three‑fold. Specifically, the report estimates that a total of about 470,000 acres in the study area has been restored over the past ten years, yet between 1.1 million and 1.3 million acres of additional restoration would be needed to generate the estimated water supply benefits. The study estimated this work would cost around $1,000 an acre, but that the economic benefits from increased water yield—particularly from hydropower—could offset a significant amount of those costs.
  • Restoration in Significant Watersheds. A nonprofit organization, Pacific Forest Trust, assessed the conditions of the five source watersheds that deliver water to the Shasta and Oroville reservoirs and determined that almost 65 percent of the forest area was significantly degraded and merited restoration. The report also identified a need to restore over 90 percent of the meadow areas in those watersheds to reestablish their ecological functions. The assessment did not contain a cost estimate for the identified restoration work.

Downstream Beneficiaries Not Contributing Much to Forest Health Activities. As discussed, the majority of the state’s developed water supply originates in its forested source watersheds, and that supply is threatened by overly dense forest conditions and wildfire risk. Yet despite the inherent interest in maintaining forest health this creates for downstream water users, few of those users are investing in maintaining the health of their source watersheds. While comprehensive statewide data are not available, our review found only a few examples of water or hydropower agencies that are opting to spend their local funds on projects to maintain or improve forest health. Instead, as discussed earlier, the bulk of funding for forest health programs comes either from the state or federal agencies.

The limited examples we found of local investments in forest health generally were from agencies receiving water and hydropower directly from nearby forests. These include the Upper Mokelumne River Watershed Authority (a joint powers authority made up of six water agencies) and the Placer County Water Agency. These groups are partnering with other agencies (such as USFS) to improve the health of their watersheds, including undertaking forest thinning and restoration projects. Additionally, a few other groups have paired local funds with state bond funds through the IRWM program to conduct water quality and restoration projects in nearby forested upper watersheds. In contrast, we found few examples of forest investments from agencies located further downstream from source watersheds—that is, those that depend on snowmelt runoff that travels longer distances through the state’s rivers and canals, such as agencies in the Central Valley or Southern California. For example, entities that contract to receive water from the federal Central Valley Project and those from the SWP have not made significant financial contributions to maintaining or improving the health of the forested watersheds above Shasta Dam and Oroville Dam, the originating sources of the water supply upon which they depend.

The connection between watershed health and water supply has received some additional attention from downstream water users in recent years, likely due in part to the increased prevalence of severe wildfires. In 2014, a coalition of five statewide groups—representing the water, forestry, rural, environmental, and agricultural sectors—formed the California Forest Watershed Alliance to advocate for increasing the pace and scale of forest restoration practices to “promote healthier, more resilient forests across California.” Additionally, in 2015 the Association of California Water Agencies issued a report recommending increased investments in improving the resiliency of California’s water sources. These initiatives, however, have stopped short of calling for downstream beneficiaries to invest their own funding in upper watershed health projects. Rather, they primarily call for increased action on the part of the state and federal governments.

Recent legislation, Chapter 695 of 2016 (AB 2480, Bloom), defines source watersheds as “integral components of California’s water infrastructure” and states that forest and ecosystem repair in those watersheds may be funded in similar ways to the maintenance and repair of other water infrastructure. The vast majority of water infrastructure projects are funded through local funds (such as revenues from water user fees), with state and federal funds typically making up a much smaller comparative share. Most local agencies have not yet begun to consider actions to improve watershed health as typical water infrastructure projects.

CalFire Not Best Entity to Oversee Proactive Forest Health Efforts. As discussed earlier, currently CalFire is the primary state entity charged with leading the state’s efforts to improve forest health and overseeing the large investments the state is making using GGRF funds (and potentially Proposition 68 bond funds, should it be approved by voters). While we think identifying a lead agency to oversee forest health efforts is important, we have two concerns with assigning CalFire with this responsibility and funding. First, housing this funding within one department makes it more challenging to involve the other state departments that typically have a role in regulating forest health activities, such as CNRA, DFW, and SWRCB. Specifically, it makes it more difficult to coordinate with other funding sources and pursue other objectives—such as protecting water quality and wildlife habitat—that fall under the jurisdiction of those other departments, as compared to if the lead entity was an agency or multi‑department team. Second, while CalFire clearly has an important role to play in contributing to the state’s forest health efforts, we believe the department’s other vital and time‑intensive responsibilities might interfere in its attempts to lead those efforts. The large number of severe fires over the past five years has demanded that CalFire dedicate even greater resources, time, and attention to its emergency response responsibilities. We are concerned that the department’s leadership may not be able to simultaneously sustain uninterrupted direction over proactive forest health efforts—such as developing and overseeing grant programs, forming partnerships with other agencies, streamlining permitting processes, and taking other steps to increase the pace and scale of restoration projects—while it is occupied with managing increasingly frequent and extreme fire emergencies across the state.

State Lacks Clear Plan for Prioritizing Use of Funding to Maximize Benefits. Given the extent of both the degraded forest conditions and the costs associated with making improvements, the state will have to undertake forest health projects on an incremental basis. The problem is too vast—and expensive—to resolve in just a few years. In light of these limitations, focusing available dollars on restoration activities in locations where they can achieve maximum impacts will be key. Yet the state lacks a comprehensive, strategic approach for making meaningful improvements in statewide forest conditions.

Although the state has appropriated hundreds of millions of dollars to improve forest health in recent years, these investments have not been guided by an overarching, coordinated strategic plan. Rather, many programs have allocated grants for activities that achieve small‑scale, project‑level benefits. In general, projects have been evaluated for funding on an individual stand‑alone basis, rather than based on how they might fit into a coordinated, broader scale effort. In the words of one stakeholder with whom we spoke, the grants the state has allocated thus far have largely achieved “random acts of restoration.” This patchwork approach is unlikely to yield meaningful progress in tackling the overall forest conditions and associated risks. Improvements on one small parcel of land will not significantly reduce fire risk or protect water supply if the surrounding parcels continue to have overly dense and unhealthy conditions.

The state has taken some recent steps to better coordinate forest health efforts. For example, the draft Forest Carbon Plan articulates some statewide goals that could help improve forest conditions. It recommends that state conservancies (there are ten in various regions across the state) develop “action plans” to prioritize improvements in their local forests. (The plan states that “alternative leadership capacity will need to be identified in areas not covered by state conservancies.”) The plan also sets some specific targets for increasing the annual rate of forest restoration and reforestation on nonfederal lands. However, the document lacks specific implementation details, such as how and when the recommended regional prioritization plans should be developed, and where the state should focus its dollars and efforts in the coming years. For example, the plan states an overall goal of increasing the rate of fuels reduction treatments on nonfederal lands from the recent average of 17,500 acres per year to 35,000 acres per year by 2020 and to 60,000 acres per year by 2030, but fails to include specific details about how or where the state should go about implementing this goal.

Another step the state has taken to better coordinate funding is the newly released grant guidelines for CalFire’s GGRF‑funded Forest Health Program. These require that proposed projects include “large, landscape‑level forestlands,” produce “multiple benefits,” and “target forestlands where projects will have the greatest benefits.” However, the guidelines list several possibilities for defining how such benefits will be defined and prioritized, including “areas with elevated levels of tree mortality and wildfire threats, carbon storage potential, [and] opportunity for biomass use.” Given that several of these characteristics currently apply to a large proportion of the state’s forests, exactly how the department will prioritize the limited funding is unclear.

Many options exist for how the state might focus its forest health efforts and funding. For example, some entities have suggested the state should prioritize restoration work in key watersheds that provide water supplies to large numbers of Californians, such as those that feed into the reservoirs behind the dams at Oroville and Shasta. Others have argued that the state should focus on preventing fires on SRA lands, and avoid spending state funds on forests that are under federal jurisdiction. Some groups advocate that in the near term, the state should prioritize funding for areas that have identified projects and existing partnerships in place because they may be able to pull together local funding and agreements more quickly and initiate work with fewer delays—such as the Tahoe Central Sierra Initiative, a component of the Watershed Improvement Program mentioned earlier. In a slightly different argument, some scientists have suggested that the state should focus its efforts primarily on higher elevation landscapes since lower elevation forests may ultimately be “lost” to the effects of climate change in the coming decades regardless of what restoration activities might be undertaken in the near term.

Undoubtedly, prioritizing one region or type of activity over another is not without trade‑offs. Given limited resources, an intensive focus in one area could mean delaying restoration work—and living with heightened risk—in another. This kind of prioritization can be difficult both politically and practically, as most regions can make a compelling case for responding to the risks associated with the current conditions of their surrounding forestlands. However, continuing a practice of spreading funding and efforts across too many regions could undermine the effectiveness of those activities. That the state adopt and follow some kind of prioritization principles and strategic approach seems vital.

Certain State Policies and Practices Can Inhibit Forest Health Activities

Requiring Plans for All Timber Sales Might Be Discouraging Additional Restoration. We find that one key component of the state’s FPR—that a THP or other timber management plan generally must be prepared any time timber is removed from the forest and sold commercially—may be inhibiting some beneficial forest restoration work. Restoration and forest management work often involves the removal of trees that could be commercially viable. When sold, the revenue generated from sales can help offset the cost of restoration activities. However, selling any forest products commercially usually requires additional documentation, such as a THP. The FPR were initially created to regulate timber harvesting on private lands in order to ensure that logging was done in a sustainable manner. At the time, the Legislature was concerned that forests were being overharvested for commercial purposes. This led to the requirement that a THP be prepared anytime harvested trees are to be sold. However, based on our conversations with stakeholders, small landowners and proponents of forest restoration projects are finding that the costs and time associated with preparing one of these plans can be cost prohibitive. They therefore often forego preparing such plans, meaning they also forego the opportunity to earn revenues from selling any marketable timber. Foregoing that revenue reduces the total number of projects that can be undertaken with limited resources. Solutions to address this concern have been attempted—most notably, the implementation of NTMP and the more recent Working Forest Management Plan program, which have fewer planning requirements for smaller landowners and are valid for a longer time period compared to THPs. While these strategies reduce regulatory costs for landowners compared to preparing THPs, they still present substantial upfront costs that are problematic for some small landowners.

Some Other State Permitting Requirements Also Can Inhibit Forest Health Activities. While the multiple state permits required to carry out many forest health activities (described in Figure 7 on page 12) are intended to protect against undue negative environmental impacts, these requirements are likely inhibiting some of the potential positive environmental effects that improved forest health could yield. (Our findings and recommendations focus on state regulatory requirements, since federal laws and permits are beyond the scope of the state Legislature’s authority to change.) Project proponents seeking to conduct activities to improve the health of California’s forests indicate that in some cases, state regulatory requirements can be excessively duplicative, lengthy, and costly, thereby delaying and limiting the pace and scale of their proposed projects. In particular, stakeholders suggest that undertaking large‑scale, multiphase treatments across many acres of forestland—referred to as “landscape‑level” projects—can be particularly difficult given existing permitting structures. This is because regulatory agencies often consider each phase of the work as a specific project needing an individual set of costly and time‑intensive permits, rather than considering and approving the overall strategy. Additionally, when entities want to use state funds to conduct a thinning project on federal forestlands, in certain cases they must conduct both the federally required NEPA review and certain components of the state required CEQA review, and undertake multiple public comment and scoping periods. As we discussed earlier, while certain permit exemptions and streamlined processes do exist—such as specific programmatic EIRs—these only apply for certain types of projects.

Constraints Limit Effectiveness of Two Landowner Assistance Programs

Several Limitations Constrain Use of Prescribed Fire. There are three main conditions that must be met in order for a prescribed burn to take place under VMP. First, all documentation—including a burn plan, CEQA compliance, and air quality permits—must be completed by the landowner and CalFire for the project in advance. Second, CalFire firefighters must be available in the same geographical area as the project in order to conduct the burn. Third, weather conditions and other factors—such as wind speed, humidity, temperature, and air quality—must be within specified limits established in the burn plan and air quality permit.

We found in different situations any of these three conditions can impede the ability of a VMP project to proceed. In some cases, weather conditions are such that a prescribed burn might affect air quality conditions in a nearby community in violation of the air quality permit. In other situations, CalFire fire crews are not available to conduct prescribed burns because they are engaged in firefighting activities. We note that in recent years, the Legislature has provided CalFire with additional year‑round firefighting staff, which should increase the department’s capacity both to combat wildfires and conduct prescribed burns and other proactive forest management activities.

In addition, CalFire has indicated that its current level of foresters who prepare and review documentation under VMP is inadequate. According to CalFire, current staff are unable to prepare enough potential projects to be ready for implementation throughout the state when and where both weather conditions and the availability of firefighting staff would otherwise permit it. Currently, CalFire has 21 foresters that spend part of their time working on the VMP program, and they are able to prepare a total of about 25 projects annually. The department is currently treating roughly 20,000 acres annually. However, a recent department analysis estimated that it has the capacity to complete 40,000 acres when taking into account the availability of firefighting staff and other constraints (such as weather conditions that would allow prescribed burns). This suggests that a major constraint on completing more VMP projects is that not enough of the documentation necessary to have projects ready to be implemented has been prepared.

Reimbursement‑Based Structure of CFIP Creates Challenges for Landowners. Stakeholders have identified barriers to utilizing CFIP, CalFire’s cost‑sharing assistance program for forest management activities. As noted earlier, this program has a reimbursement‑based structure, where landowners enter into an agreement with CalFire and undertake work on their lands, then receive payment for a share of the costs once the work is completed. Many of these small landowners, however, do not have the necessary money, equipment, or personnel on hand to cover the full upfront costs of the work authorized by CFIP. This limits the number of landowners who are able to participate in CFIP, and potentially also the acreage of private forestland being actively managed.

Limited Options for Using and Disposing of Biomass Can Inhibit Forest Thinning Projects

Limited Uses for Thinned Materials Can Inhibit, Increase Costs of Forest Management. Some stakeholders report that costs associated with the limited options for utilizing or disposing of woody biomass can prohibit them from undertaking projects that would improve the health of their forestlands, or limit the amount of acres they are able to thin. As discussed earlier, woody biomass typically is not useable in traditional lumber mills. This is because these byproducts of timber harvest or thinning operations may be of an undesirable species, too small in diameter for lumber production, or malformed. Historically, much of this excess forest product was burned to produce bioenergy. However, a significant number of bioenergy facilities have closed over the course of the past two decades. Specifically, in 1991, there were 54 woody biomass processing facilities across the state, with the capacity to produce around 760 megawatts of electricity. In contrast, at the end of 2017 there were only 22 operational facilities with a total capacity of 525 megawatts. These closures have occurred as facilities—largely built in the 1980s—fell out of compliance with more modern air and energy standards, and as bioenergy has increasingly had to compete with cheaper energy sources such as wind, solar, and natural gas.

With fewer available facilities, the distances biomass must be shipped for processing have increased, correspondingly increasing the overall costs of forest thinning projects for landowners and project sponsors. Hauling woody biomass is particularly costly due to its weight. Some additional items can be produced using woody biomass, including landscaping materials, compost, and products that are manufactured from wood chips or pellets. These items, however, generally are too low in value to offset the costs of transporting biomass to facilities for their production. As discussed in the nearby box, other states such as Oregon have been successful in providing market incentives for the development of new products and adoption of engineered wood products into construction and other uses. California has not taken significant steps towards similar efforts. However, legislation—Chapter 368 of 2016 (SB 859, Committee on Budget and Fiscal Review)—established a Wood Products Working Group to explore options for expanding the wood products market. The group released a report in October 2017 that recommended (1) removing barriers and encouraging market development for wood products, (2) promoting innovation, and (3) investing in human capital. The report offered various strategies to accomplish each recommendation, including outreaching to local planning offices and developers regarding new building codes that allow for new timber uses, conducting pilots or competitions for new wood products (similar to Oregon), and expanding partnerships with community colleges and the California Conservation Corps to develop workforce capacity in the forestry and wood products sectors.

Oregon Incentivizing Development of New Wood Technologies

The state of Oregon recently took actions to incentivize the development and implementation of cross‑laminated timber (CLT), a new use for woody biomass, that could provide a model for California.

CLT is a wood building product used for framing buildings that is made by bonding layers of lumber. The technology allows the use of smaller pieces of wood that cannot be used in traditional wood beams, meaning it can utilize the biomass produced from forest management activities like thinning. The International Building Code for 2015 recognizes CLT for use in most buildings.

While CLT has been used in Europe since the 1990s, it is relatively new to North America. The state of Oregon recently took steps to introduce the manufacturing technology in the United States. Specifically, the state’s economic development agency provided a $150,000 grant for CLT research at Oregon State University and to plan a production line at a mill in a small town in the southern part of the state. The result was the first and only American company to be certified by the American Plywood Association to produce CLT. Subsequently, Oregon provided a loan to the mill for the costs of building the new production line and launched a $200,000 CLT design competition. Grants from the federal government and industry groups helped pay for testing. The competition resulted in a condominium building and parking garage made of CLT in Portland. Currently, an 11‑story timber high‑rise made from CLT is planned in downtown Portland, which would be the nation’s first high‑rise building made from wood. CLT is also used for housing and other smaller buildings.

These examples show that relatively small state programs can help in furthering development of the wood products industry. California could be a key region for CLT adoption, particularly since it is a large market for earthquake retrofitting, and certain CLT buildings have performed very well in seismic resistance testing. A federally funded study conducted by an Oregon nonprofit recommended several state actions that could increase investment in and use of CLT, including (1) providing grants or subsidies for equipment, (2) offering loan guarantees on equipment or capital investments, (3) working to change building codes to encourage the use of CLT in Oregon as well as surrounding states, (4) providing outreach and education to engineering and design firms, and (5) providing streamlined permitting for buildings that use CLT.

Disposing of Unutilized Biomass Can Be Challenging. As discussed earlier, biomass that is not utilized is most frequently disposed of by open pile burning. While this approach is often less expensive than efforts to use biomass, it still requires landowners to invest significant time, planning, and funding. These challenges can also create barriers for undertaking forest thinning projects. Typically, open pile burns require air quality permits from local air districts, burn permits from local fire agencies, and potentially other permits depending on the location, size, and type of burn. To reduce smoke, permits restrict the size of burn piles and vegetation that can be burned, the hours available for burns, and the allowable moisture levels in the material. These restrictions limit the amount of biomass that can be disposed of and increase the per‑unit disposal costs. While the Regulations Working Group of the Tree Mortality Task Force recently issued new guidelines—under the authority of the Governor’s tree mortality‑related executive order—for high hazard zone tree removal that relaxed some of those permit requirements, these exceptions only apply in areas of extreme tree mortality. For example, the guidelines allow more burning to take place under different weather conditions, such as slightly higher wind or temperature conditions.

The state has had some success in mitigating these challenges and increasing biomass disposal in areas with high tree mortality by utilizing “air curtain burners,” which are portable incinerators designed to produce less smoke and GHG emissions than open pile burns. Because they are contained and have a smaller impact on air quality, the use of air curtain burners is not as limited by weather conditions or permitting requirements. Currently, CalFire has ten burners, which have been distributed to areas that have experienced high rates of tree mortality.

Recommendations

In this section, we recommend steps the Legislature could take to address the barriers highlighted above. We begin by providing an overview and some overarching comments that apply to our package of recommendations, then we describe specific recommendations in each of the four broad categories we highlighted in the previous section: funding and coordination, policies and practices, local assistance programs, and disposal of woody biomass.

Overview of Recommendations

Figure 14 summarizes our various recommendations to improve the health of the state’s forested watersheds. These recommendations encompass both larger actions—such as significant expenditures for landscape‑level forest health projects—as well as some more moderate steps that we believe could help achieve improved outcomes. Two overarching issues cut across several of our specific recommendations: (1) which state entity should oversee and lead forest and watershed health efforts and (2) what fund sources should support the costs of the additional actions we recommend. Below, we first discuss each of these crosscutting issues.

Figure 14

Summary of Recommendations

  • Improve and Increase Funding and Coordination
  • Recognize the statewide benefits healthy forests can provide by maintaining at least the current level of funding—$280 million—annually for forest treatment projects.
  • Take steps to generate additional investments from downstream beneficiaries by:
    • Requiring the State Water Project to make an annual spending contribution to maintain the health of the Feather River watershed.
    • Appropriating $2 million for pilot projects for local water and hydropower agencies to conduct wildfire cost‑avoidance and cost‑benefit studies.
    • Modifying grant criteria for the Integrated Regional Water Management program to encourage spending on watershed health projects.
  • Designate CNRA—rather than CalFire—as the lead agency to oversee proactive forest and watershed health funding and initiatives.
  • Ensure that future spending is based on clear prioritization criteria to make meaningful progress on achieving statewide goals.
  • Revise Certain State Policies and Practices to Facilitate Forest Health Activities
  • Allow the sale of timber without a timber harvest management plan when the primary purpose of the project is forest health in order to help offset the costs of beneficial forest thinning projects.
  • Direct CNRA to submit a report proposing options for how the state might streamline forest health project permitting requirements.
  • Improve Landowner Assistance Programs to Increase Effectiveness
  • Allocate funding to CalFire for additional forester positions to increase the department’s use of prescribed fire through its Vegetation Management Program.
  • Restructure California Forest Improvement Program payments to reduce the burden on small landowners by providing partial payments in advance of work being undertaken.
  • Expand Options for Utilizing and Disposing of Woody Biomass
  • Support the development and incentivize the use of nontraditional wood products by appropriating funding for a pilot grant program.
  • Increase opportunities for disposing of biomass by:
    • Requiring CalFire and CARB to analyze when burn permit requirements could be eased.
    • Appropriating funding to purchase additional air curtain burners based on an analysis by CalFire.

CNRA = California Natural Resources Agency; CalFire = California Department of Forestry and Fire Protection; and CARB = California Air Resources Board.

Larger Role for CNRA. One common theme across several of our recommendations is enhancing the role that CNRA plays in the state’s forest and watershed health efforts. As described earlier, the agency currently heads up some forestry‑related activities, including THP reviews and certain TRFRF programs, but CalFire oversees most of the state’s forest health grants. Our recommendations envision CNRA taking a greater role in coordinating, overseeing, and reporting to the Legislature on the state’s forest health activities. As described below, we believe the agency is well‑positioned to bring together multiple state departments—including CalFire—to take proactive steps to increase the pace and scale of forest restoration efforts.

Multiple Funding Options, Though Each Comes With Trade‑Offs. Given the magnitude of problematic conditions across the state’s forested watersheds, many of our recommended actions—unsurprisingly—would result in additional costs. We do not identify specific funding sources for each activity, as the Legislature has multiple options upon which it could rely.

Some of the costs associated with our recommendations would be significant, such as to increase the pace and scale of large forest treatment projects. To make meaningful progress on improving existing forest conditions, the state would need to rely on funding sources that can support significant—multimillion dollar—levels of spending for these landscape‑level projects, such as the General Fund and GGRF. Other recommended actions, however, encompass more modest steps that are intended to help support the larger goal of improved conditions. For these activities—such as implementing cost‑benefit analyses, developing alternative wood products, or purchasing new air curtain burners—the Legislature also has the option of using funding sources that are able to support smaller, less‑costly expenditures. Such sources include TRFRF and the Environmental License Plate Fund, which provides roughly $50 million annually from the sale of license plates for environmental programs and projects.

For all of these funding sources—both large and comparatively smaller—the Legislature already faces many competing priorities. Directing funding to address forest and watershed health and implement our recommended actions would mean less funding available from any of these sources for other state expenditures. As with all its budgetary decisions, the Legislature will have to balance its multiple priorities. We believe the risks associated with failing to address the condition of the state’s forests and watersheds merit consideration of our recommendations despite their associated costs. Our recommendations also include steps to require and encourage greater spending from downstream entities to help pay the costs of sustaining the healthy forests on which they depend.

Improve and Increase Funding and Coordination

Recognize Statewide Benefits From Healthy Forests by Maintaining at Least the Current Level of State Funding. Given the scale and importance of the state’s forests and the risks associated with their current conditions, we find it prudent for the state to prioritize spending to improve forest health. While federal and local entities must continue to play a role in helping to address—and pay for—these large and costly efforts, the state’s interest in avoiding the adverse impacts associated with unhealthy forests means that providing some state‑level funding is also vital. As noted earlier, recent levels of funding are not keeping pace with forest restoration needs, and this is already contributing to negative consequences such as severe wildfires.

Determining how much to provide for these activities is difficult, given the large need and competing state budget priorities. As a first step, we recommend providing annual appropriations of roughly the same amount that was provided for these efforts in 2017‑18—$280 million. These funds could be used for a combination of efforts, such as issuing grants for local projects—including through the Sierra Nevada Watershed Improvement Program—as well as to increase the amount of acres treated through CalFire’s VMP and CFIP programs. Given the patchwork of ownership and cross‑jurisdictional risk, we believe funds should be made available for projects both on SRA lands as well as nearby federal lands. In many cases, federal agencies have projects identified and ready for implementation, but do not have sufficient funds to complete them.

The Legislature primarily used GGRF in the current year to support forest restoration activities, and the Governor is proposing an additional $160 million from GGRF on a one‑time basis in 2018‑19. We think this is an appropriate fund source for such activities, given the GHG risks and benefits associated with forest conditions. However, the General Fund would also be an appropriate fund source given the statewide benefits forests provide. Additionally, we find that it would be reasonable for the Legislature to include funding for forest and watershed health in any general obligation bonds it may propose in future years for resource‑related activities, given the large upfront costs and long‑term statewide benefits associated with these projects. (As noted earlier, the Legislature has set aside funding for forest and watershed health activities from the proposed bond it has placed before voters in June 2018.)

Take Steps to Generate Additional Investments From Downstream Beneficiaries. Together with providing additional funding, we believe the state should also help encourage water and hydropower agencies to spend local funds to help maintain and improve the health of their forested source watersheds. These downstream entities are direct beneficiaries of healthy watersheds and face risks to their water supply and quality from wildfires and overly dense forests. As such, the state should expect that they contribute to improving forest conditions. We recommend the Legislature take the following three steps to help generate such investments:

  • Require Annual Contribution From SWP to Help Maintain Health of Feather River Watershed. We recommend the Legislature adopt budget bill language establishing an annual requirement that DWR spend a specified amount on projects to maintain and improve the health of the Feather River watershed above Oroville Dam, and directing the department to recover the costs through its SWP contracts. While determining exactly how much funding SWP beneficiaries should pay to protect their water source is somewhat subjective, we believe this spending requirement should be enough to support ongoing, cumulative wildfire prevention work in the watershed without imposing an undue financial burden on downstream ratepayers. For example, the Legislature could require that DWR spend $10 million per year for these projects. The entities that contract for that water currently pay roughly $1.2 billion each year for the operations of that system. Restoration and maintenance of source watersheds should be a component of regular SWP expenditures, and recent legislation clarified that this is an important and allowable infrastructure expenditure. DWR should work with the interagency Forest Health Team at CNRA to determine which projects to fund each year. We also recommend that the Legislature direct DWR to explore and report back on options for how the state might encourage the federal government to invest in maintaining and restoring the forested source watersheds that supply the Central Valley Project system.
  • Provide $2 Million for Cost‑Benefit Studies. We recommend the Legislature appropriate $2 million in one‑time funding for DWR to initiate a number of pilot projects for local water and hydropower agencies to conduct wildfire cost‑avoidance and cost‑benefit studies. We recommend DWR use this funding to allocate competitive grants to local agencies, and that the grants include a local cost‑share requirement so the state does not bear the full cost of conducting the studies. We estimate each study would cost between $250,000 and $1 million to complete in total. As with the Mokelumne study described on page 25, we believe this could help local agencies define the benefits and risks associated with their source watersheds. The information from these studies could then help those agencies provide evidence to their ratepayers of the value of investing additional local funds in maintaining the health of those watersheds. We recommend including a requirement that DWR compile these reports on its website so that other agencies and communities can also easily access and learn from this state‑funded research.
  • Incentivize Upper Watershed Projects Through IRWM Program. We recommend encouraging local entities to use local funds (paired with state IRWM grants) for watershed health projects by directing DWR to include incentives for undertaking such projects in the IRWM grant application process. Generally, IRWM grants are allocated as competitive grants to local agencies, and applicants must commit to funding a portion of the project’s cost (typically 50 percent) with local monies. We recommend that the Legislature require DWR to structure future IRWM grant programs such that regions that opt to undertake projects improving upper watershed health (1) are awarded additional points in the scoring of competitive grants applications and/or (2) face lower local cost‑share requirements (for example, 30 percent rather than 50 percent). These incentives would encourage IRWM regions to invest in projects that benefit their water supply and quality even if they are implemented upstream and outside of their region. These new grant conditions could be imposed for IRWM grants from future bonds. Moreover, the Legislature could direct DWR to apply prioritized application scoring for the roughly $200 million in IRWM funds remaining to be appropriated from Proposition 1 (the 2014 water bond). (Proposition 1 language prohibits changes to local match requirements.)

Designate CNRA as Lead Agency for Proactive Forest and Watershed Health Funding and Initiatives. We recommend the Legislature task CNRA with heading up a multi‑department Forest Health Team to improve the health of the state’s forests and watersheds. We recommend this team build upon the collaborative group formed by AB 1492 in 2012, consisting of CNRA, DFW, SWRCB, and CalFire. While CalFire has expert knowledge of the state’s forestry needs and priorities, a more collaborative approach across several departments could help ensure that multiple funding sources are coordinated and that selected projects align with other state objectives such as preserving water quality, reducing GHG emissions, and protecting fish and wildlife. This is one of the reasons the Legislature enacted AB 1492 to move the THP and permit review program from CalFire—where it previously was housed—to CNRA. Moreover, shifting leadership over forest and watershed health activities to CNRA could help ensure they remain an agency priority even during active wildfires when CalFire staff are—understandably—preoccupied with emergency response. The Forest Health Team could also call upon the Tree Mortality Task Force for insight and advice on how the state should proceed in addressing forest and watershed health issues, given the breadth of perspective and expertise this group can offer.

One of the most important responsibilities of this new multi‑department team would be overseeing forest health funding. When the Legislature appropriates future funding from GGRF or other sources for forest and watershed health efforts, we recommend it designate CNRA as the lead agency to oversee those appropriations. CalFire—along with the other involved departments—still would play a role in helping CNRA determine which efforts and projects to fund; however, it would not be the sole administering entity. Proposition 68 would provide an additional $15 million in forest health funding to CalFire (in addition to $25 million that CalFire would be required to pass along to the Sierra Nevada Conservancy for the Watershed Improvement Program). Should the bond be approved by voters in June 2018, we recommend the Legislature require that CalFire consult with our proposed CNRA‑led multi‑department Forest Health Team in making allocation decisions for those funds.

Ensure Future Spending Is Based on Clear Prioritization Criteria to Achieve Maximum Benefit. We recommend that prior to appropriating additional funding to improve forest and watershed health, the Legislature require the administration to report on how such funds will be targeted for maximum statewide benefit. Given the scale of problematic conditions across California’s forests, the state must be strategic in its investments to maximize incremental progress towards its goals—reducing fire risk, protecting water supplies, and sequestering GHG emissions. While some prioritization criteria have been set out in the state’s draft Forest Carbon Plan and CalFire’s GGRF‑funded Forest Health Program, these continue to lack specificity. As discussed earlier, continuing a practice of spreading funding and efforts across too many regions is likely to undermine the effectiveness of those activities.

We do not believe the recommended report need be voluminous nor take many months to compile. Rather, the administration could build upon previous efforts—including the Forest Carbon Plan and existing grant programs—to clearly explain to the Legislature how funding proposed for allocation would make meaningful progress on achieving statewide goals, and in particular how the funds would be used to encourage larger landscape level projects. Such a report could be included within a budget change proposal for the requested funding, or as a stand‑alone document. Should the Legislature feel that this initial report lacks sufficient detail or find the proposed strategy unsatisfactory, it could request a more extensive strategic planning effort to guide forest health expenditures in the future.

As discussed above, we believe CNRA is the best agency to coordinate and oversee proactive forest health efforts and grant programs and therefore would likely be the best agency—together with our recommended multi‑department Forest Health Team—to provide such a report to the Legislature. However, should the Legislature continue to appropriate most funds for forest health activities to CalFire—from GGRF or other sources—this responsibility should correspondingly fall to that department.

Revise Certain State Policies and Practices to Facilitate Forest Health Activities

Allow Sale of Timber Without Management Plans Under Certain Limited Circumstances. In order to help increase the acreage of thinning projects on nonindustrial lands, we recommend that the Legislature amend the Forest Practice Act to allow landowners and restoration projects to sell some commercially viable timber without having to complete a timber management plan when the primary purpose of the project is to improve forest health. While not required to complete a harvest plan, under our proposal landowners would need to secure an exemption from CalFire certifying that the project was for the purpose of improving forest health, and the landowner would be required to acquire any other relevant permits. In making such a change, the Legislature would want to be careful about defining which projects are eligible for this exception in order to avoid any unintended consequences, such as detrimental overharvesting. Retaining other environmental permitting requirements could help ensure these projects do not result in undue negative impacts. Within clear and narrow parameters and appropriate regulatory oversight, we think limited expansions of sales of commercially viable timber could promote additional activities that benefit forest health.

Statute already allows for some exemptions from timber management plans for commercial harvest when specific conditions are met and the activity addresses an important state need. For example, Chapter 583 of 2016 (AB 1958, Wood) allows THP exemptions for commercial removal of very specific trees when that removal is part of a project to restore and conserve California black or Oregon white oak woodlands. That legislation provides examples of reasonable limitations that could be replicated under our recommended approach, such as specifying: the maximum diameter, number, and species of trees that can be harvested; the radius from the restoration area that can be harvested; and the restoration activities that must take place. Providing similar exemptions from THPs and other timber management plans for landowners or restoration projects where forest thinning efforts are most needed—coupled with strict parameters around when such exemptions might be used—could potentially allow these landowners and project proponents to recoup some of their costs from restoration. This, in turn, could allow some projects that would otherwise be cost‑prohibitive to move forward or free up additional funding to potentially increase the amount of acreage thinned.

Direct CNRA to Propose Options for Streamlining Forest Health Project Permitting Requirements. To expedite and facilitate implementation of larger scale forest health projects, we recommend exploring opportunities to reduce some of the duplication, costs, and time delays associated with the regulatory review process for forest restoration projects. Ensuring that unintended negative environmental impacts are avoided is important, and of course this is the point of the regulatory process the state has put in place. However, modifying the current review process could avoid inhibiting forest health activities that are intended to create an overall benefit in environmental conditions, such as by avoiding catastrophic wildfires that have the potential to cause even greater damage.

Specifically, we recommend the Legislature adopt legislation directing CNRA to submit a report to the Legislature recommending options for streamlining permitting requirements to facilitate and expedite large‑scale forest health projects. We also recommend requiring that CNRA convene an advisory group to provide input into the development of this report. Members of this group should include stakeholders from the involved state regulatory agencies (such as CalFire, DFW, and the state and regional water quality control boards), agencies frequently involved in funding forest health projects (including the Sierra Nevada Conservancy), and other involved stakeholders such as environmental groups, forestry organizations, and landowners. As a model for this work, the agency can build upon the collaborative groups convened and the streamlined processes implemented pursuant to AB 1492, as that effort had similar participants and goals. We recommend the legislative report address the four topics outlined in Figure 15: (1) problems with the current system that lead to delays and duplication of effort, (2) how to preserve important environmental protections under a more streamlined permitting system, (3) options for reform that could be accomplished under current law, and (4) options that would require new legislation to implement. We recommend that CNRA submit its report to the Legislature no later than May 1, 2019.

Proposed Focus Topics for Forest Health Regulatory Streamlining Report

Recommended Reporting Requirement for the California Natural Resources Agency (CNRA)

  • Issues With the Current System. What are specific shortcomings with the current process for permitting forest health projects? Where do delays, duplications of effort, and bottlenecks occur?
  • Preserving Important Protections. What considerations and safeguards would need to be included in a streamlined permitting system to ensure that adequate environmental protections are maintained and to avoid significant negative consequences (for example, ensuring against presenting opportunities for clear‑cut timber harvesting)? How might the state go about maintaining such assurances while facilitating the environmental benefits of improved forest health?
  • Options Under Current Law. What options for simplifying regulatory oversight to escalate the pace and scale of forest health projects could be accomplished under existing law (for example, expanding the use of programmatic Environmental Impact Reports or permits for special pilot projects)? What are the associated trade‑offs and why are agencies not currently pursuing these options? Are there steps that CNRA or departments should take to more aggressively pursue these options?
  • Options Requiring Legislation. Which simplification options might require new legislation to enact (for example, establishing a new multiagency “umbrella” permit for forest health projects that functions similar to a Timber Harvest Plan)? What are the associated trade‑offs and reasons the Legislature should or should not pursue these options?

We believe the second topic noted in the figure—preserving important protections—is particularly important because forest treatment projects conducted without proper mitigation can result in negative environmental impacts (such as to water quality or fish and wildlife) even when improving conditions is the overall goal. As such, we do not recommend that the Legislature extend blanket CEQA exemptions for all forest health projects. Similarly, we do not recommend waiving endangered species protections for forest management projects (as has been suggested in some recent legislative proposals at the federal level). Our recommended approach seeks to expedite and expand projects to improve forest conditions while maintaining essential regulatory oversight and avoiding unintended negative impacts.

Improve Landowner Assistance Programs to Increase Effectiveness

Allocate Additional Funding to CalFire to Increase Use of Prescribed Fire. We recommend increasing CalFire’s capacity to identify, plan, and implement prescribed fire projects by increasing funding for the VMP. Specifically, we recommend the Legislature increase funding for the forester positions who prepare and review the documentation for prescribed burns by a few million dollars annually above the program’s current funding level of $10 million. Under the VMP, CalFire foresters help design prescribed fire projects and ensure projects are in compliance with CEQA, air quality requirements, and other state laws before they can be implemented. Increasing staff capacity could expedite project documentation and approval processes, thereby increasing the number of prescribed burns CalFire and landowners are able to complete. We note that increasing firefighter capacity could also have the potential to increase the likelihood that a prescribed burn project could take place. However, the Legislature has provided CalFire with increased firefighting resources in the past few years, while funding for VMP foresters has not increased. We also note that additional foresters could result in an increase in the number of prescribed fire projects that landowners and other entities could implement independent of VMP. According to CalFire, its current level of resources is not sufficient to be able to provide technical assistance on such projects.

Provide Partial Advance Payments for CFIP to Reduce Burden on Small Landowners. To encourage greater landowner participation in the program and reduce the financial burden placed on participants, we recommend making changes to how CFIP payments are made to landowners. Specifically, we recommend that the Legislature authorize CalFire to provide landowners with a share—for example, up to one‑half‑of the state’s cost‑share payment—in advance of the work being undertaken. While participants still would need to fund their own portions of the project costs as well as pre‑fund a part of the state’s share, we believe removing a portion of the upfront investment needed to complete the work could encourage greater participation in CFIP. This, in turn, could increase the number—and associated acreage—of landowners investing in improving the health of their own lands. The program already has provisions in place to ensure state funding is protected. For example, CFIP already requires a binding upfront legal agreement between the state and landowners regarding the scope of work to be completed, as well as repayment provisions should participants not fulfill the agreed upon terms. Moreover, the state already conducts oversight of program participants both during and after the work, so it would have assurances that program participants used the funding to implement the work per the agreement. The state could also consider imposing additional safeguards, such as provisions requiring applicants to offer collateral as a condition of the upfront payment, to help ensure the state is able to recapture funds that are not appropriately used. As discussed above, 9 million acres of forestland in California are owned by nonindustrial landowners and nearly 90 percent of these owners have less than 50 acres of forestland. As such, improving the health of these privately held forestlands is an essential component of the state’s overall forest management strategy, and CFIP can be one mechanism to help achieve such improvements.

Expand Options for Utilizing and Disposing of Woody Biomass

Support Development and Incentivize Use of Nontraditional Wood Products. As discussed above, thinning and other forest health activities result in woody biomass—small trees, brush, limbs, and other forest residue. Some of the challenges associated with utilization of biomass are difficult for the state to address directly. For example, the value of biomass is very low relative to the costs of transporting and processing it, and simply subsidizing biomass projects—as some have suggested—could be quite costly. However, there are other actions the state can take that could result in increased utilization of woody biomass. Specifically, we recommend the Legislature provide CNRA with a few hundred thousand dollars to implement competitive grant programs for pilot projects to create and support expanded uses for woody biomass. California could model such projects on similar efforts that have shown success in Oregon, or been recommended by the Wood Products Working Group. Grants of roughly a couple hundred thousand dollars or less could be awarded to small businesses, nonprofit organizations, and academic institutions to help develop and deploy new wood products, manufacturing capacity, and uses. If successful, development and demonstration of new technologies made from woody biomass could encourage private industry to expand future uses. To the extent this increases biomass utilization, it could help offset the costs of some forest health activities and avoid the GHG emissions and other environmental damage from allowing biomass to decompose or burning it. We also recommend that CNRA provide evaluations to the Legislature on the outcomes of the pilots, as well as potential benefits and challenges associated with expanding such efforts.

Increase Opportunities for Disposing of Biomass. Among its multifaceted response to the tree mortality crisis, the state has adopted two actions on a limited scope that we believe could be expanded to help improve forest health more broadly.

First, we recommend the Legislature require CalFire and CARB to analyze whether there are circumstances during which the benefits of open pile burning undertaken to help thin forests might outweigh short‑term negative effects. As discussed above, open burning typically requires special permits and is subject to other limitations such as weather. However, some of these requirements have been relaxed in certain regions experiencing high tree mortality. We recommend directing the departments to explore whether these types of modifications should be expanded to other regions of the state in order to respond to forest thinning operations that are not directly related to the tree mortality crisis. While we acknowledge that burns can have negative effects on air quality and carbon emissions, we think there are circumstances in which those effects could be justified due to greater benefits—especially wildfire avoidance and long‑term forest health—that could result in less carbon emissions and better air quality over time. Therefore, it is important that both departments consider all of the potential long‑term benefits when developing regulations related to open pile burning.

Second, as discussed above, the state acquired ten air curtain burners in order to help with biomass removal related to the tree mortality crisis. Air curtain burners are relatively inexpensive (between $50,000 and $100,000 each) and can be moved around the state to support projects as needed. We recommend the Legislature direct CalFire to identify areas or projects where there are few options for biomass utilization, and where permitting or weather conditions frequently limit open pile burning. Identifying these regions would help determine how many burners should be purchased. Based on this analysis, we recommend the Legislature appropriate funding to purchase the number of additional air curtain burners that CalFire can demonstrate would effectively increase statewide biomass disposal capacity.

Conclusion

The extensive forestlands stretching across the state provide numerous benefits to California residents. Among the most crucial are the water supplies that originate in the forested watersheds along the Southern Cascade and Sierra Nevada mountain ranges, and flow downstream to millions of Californians across the state. These benefits, however, are at risk. The catastrophic wildfires that have plagued the state in recent months and years could serve as a concerning harbinger of future trends, should the state not take immediate action to improve the health of its forests. Moreover, a changing climate brings increased urgency to preserving forests’ role in sequestering GHGs and slowing the rate of global warming. While the extent of deteriorated forest conditions is daunting, progress towards making improvements is both achievable and essential.
