California's forest resources: forest inventory and analysis, 2001-2010.
This report highlights key findings from the most recent (2001-2010) data collected by the Forest Inventory and Analysis program across all forest land in California, updating previously published findings from data collected from 2001 through 2005 (Christensen et al. 2008). We summarize and interpret basic resource information such as forest area, ownership, volume, biomass, and carbon stocks; forest structure and function topics such as biodiversity, forest age, and dead wood; disturbance information such as tree damage, fire, and invasive plants; and tree growth, mortality, and removals for timber products. Consistent sampling across different ownerships and forest management regimes now allow comparisons. The appendices provide details on inventory methods and design and include summary tables of data, with statistical error, for the suite of forest characteristics inventoried.
