All volumes reported in thousand board feet (MBF) Scribner. Ownerships considered private include: Industrial private (Industry), Nonindustrial private forests (N.I.P.F), and Native American tribes (Tribal). Ownerships considered public include: CAL FIRE (State), United States Department of Agriculture Forest Service (Forest Service), Bureau of Land Management (BLM), County and Municipal (Other Public).



All of the timber harvests occurring on private lands were collected from the California Board of Equalization. These data are based on state timber yield tax. It should be noted that for the State of California it was not possible to separate out harvests by private ownership category, so all private ownership timber harvests presented here have been summed together.

For timber harvests occurring on lands managed by CAL FIRE, data were collected from CAL FIRES annual reports.



For timber harvests on the Bureau of Land Management (BLM) timberlands, data were collected from the BLM Timber Harvest Information System, located at the Denver, Colorado office. This system separates timber harvests into four categories: commercial harvests, fuel wood, special forest products (timber harvests that are too small to be viewed as commercial), and stewardship contracting. The BLM data presented here represent the sum of these four categories. BLM data can be found at: http://www.blm.gov/or/resources/forests/blm-timber-data.php



For timber harvests occurring on U.S. Forest Service lands, data were compiled from annual U.S. Forest Service Automated Timber Sales Accounting System-Volume and Harvested Revenue-State and County Summaries from 2001-2012. Data were retrieved in fiscal year by quarter and converted to calendar year by subtracting the October-December quarter data from prior fiscal year and adding the October-December quarter data from the subsequent fiscal year. Forest Service data include all convertible products including fuelwood and non-saw material.
