Book Description
This Preliminary Assessment was prepared in response to the California Forest Resources Assessment and Policy Act of 1977 (FRAPA). This Act was passed to improve the information base upon which State resource administrators formulate forest policy. The Act provides for this report and a full assessment by 1987 and at five year intervals thereafter. Information is presented under the following chapter titles: introduction to the forest resources assessment program; the forest area: a general description; classifications of the forest lands; the watersheds; forest lands and the air resource; fish and wildlife resources; the forested rangelands; the wilderness; forest lands as a recreation resource; the timber resource; wood energy; forest lands and the mineral, fossil fuels, and geothermal energy resources; mathematically modeling California's forest lands; vegetation mapping using remote sensing technology; important forest resources legislation; and, State and cooperative State/Federal forestry programs. Twelve indexes, a bibliography, and glossary are included. (JGB).

Book Description
Of California's almost 100 million ac, about a third are forested (32 million ac). This report, including the accompanying tables, summarizes key findings from the 5,369 Forest Inventory and Analysis (FIA) plots measured in California's forests during the period 2006-2015. Estimates are provided for forest area, ownership, species composition and distribution, size and age classes, volume, biomass, carbon, dead and downed wood, and understory vegetation. Starting in 2001, plots were measured on a 10-year cycle (10 percent of all plots measured annually). Thus, those plots measured in 2011-2015 represent completion of half of the remeasurement cycle; estimates of growth, mortality, and removals from remeasured plots are also included. The U.S. Forest Service manages about half of California's forested land--48 percent. Fifty-two percent of California's forests is categorized as timberland (unreserved forest land capable of producing ≥20 ft of wood per acre per year) predominantly consisting of the California mixed-conifer type. The most common forest type on the remaining 48 percent was western oak. Mean annual gross growth was 1.99 billion ft/year. Subtracting harvest removals (21 percent of growth values) and mortality (45 percent of growth values) still resulted in a positive net growth of 673 million ft/year. Of some of the commercially important tree species, damage was present in 17 to 27 percent of the trees, including Douglas-fir (17 percent), white fir (27 percent), ponderosa pine (20 percent), and redwood (17 percent). The two most prevalent nonnative species were both grasses--cheatgrass (estimated 277,000 ac of cover) and ripgut brome (234,000 ac). During the 10-year period, the years with the most forested acres with evidence of fire were 2008 and 2015. FIA plots will continue to be measured as stipulated by the 1998 Farm Bill. By the time the next FIA report for California is issued, a complete remeasurement cycle will have been completed.

Book Description
This book is a product of the initial phase of a broader study evaluating the voluntary and regulatory compliance protocols that are used to account for the contributions of forests in U.S.-based greenhouse gas (GHG) mitigation programs. The research presented here is particularly concerned with these protocols’ use of the USDA Forest Service’s Forest Inventory and Analysis (FIA) data to describe forest conditions, ownership, and management scenarios, and is oriented towards providing regulators and other interested parties with an objective comparison of the options, uncertainties, and opportunities available to offset GHG emissions through forest management. Chapters focus on the protocols for recognizing forest carbon offsets in the California carbon cap-and-trade program, as described in the Compliance Offset Protocol; U.S. Forest Projects (California Air Resources Board, 2011). Readers will discover the protocols used for quantifying the offset of GHG emissions through forest-related project activity. As such, its scope includes a review of the current methods used in voluntary and compliance forest protocols, an evaluation of the metrics used to assign baselines and determine additionality in the forest offset protocols, an examination of key quantitative and qualitative components and assumptions, and a discussion of opportunities for modifying forest offset protocols, in light of the rapidly changing GHG-related policy and regulatory environment. Finally, the report also discusses accounting and policy issues that create potential barriers to participation in the California cap-and-trade program, and overall programmatic additionality in addressing the needs of a mitigation strategy.

Book Description
This report highlights key findings from the most recent (2001-2005) data collected by the Forest Inventory and Analysis Program across all forest land in California. We summarize and interpret basic resource information such as forest area, ownership, volume, biomass, and carbon stocks; structure and function topics such as biodiversity, forest age, dead wood, and hardwood forests; disturbance topics such as insects and diseases, fire, invasive plants, and air pollution; and information about the forest products industry in California, including data on tree growth and mortality, removals for timber products, and nontimber forest products. The appendixes describe inventory methods in detail and provide summary tables of data, with statistical error, about the suite of forest characteristics inventoried.
