The Fire Perimeters data consists of CDF fires 300 acres and greater in size and USFS fires 10 acres and greater throughout California from 1950 to 2003. Some fires before 1950, and some CDF fires smaller than 300 acres are also included. BLM fires are complete since 2002 for fires greater than 10 acres in size. Integration of historical BLM fires is incomplete and work is ongoing . NPS fires greater than 10 acres in size are complete for only two parks -- Sequoia-Kings Canyon and Yosemite. Efforts to integrate remaining NPS fire history is ongoing. In 2002 criteria expanded for new CDF fires to include timber fires greater than 10 acres, brush fires greater than 50 acres, grass fires greater than 300 acres, wildland fires destroying three or more structures, and wildland fires causing $300,000 or more in damage. To ensure high quality fire perimeters data are avialable to the public and to cooperating agencies. This layer should not be used for statistical analysis. When compared to the Wildfire Activity Statistics Report it is only 90% complete. The Wildfire Activity Statistics Report is created annually by the California Department of Forestry and Fire Protection.
