Prescribed fires consume and rearrange natural fuel on the landscape. This data is used to update fuel models maintained by CAL FIRE and its cooperating agencies, other state departments and private organizations. Treatments are tracked as part of the California Strategic Fire Plan in order to identify where previous fire use allowed wildfire to be fought at a lower cost and helped prevent losses.
The "rxburn" dataset contains perimeters from multiple agencies, representing prescribed fires, fire use, machine pile burns, hand pile burns and jackpot burns, with associated tabular data for responsible agency, project number, project name, start date, acres reported and more. Data provided are merged from sources of varying quality. There has been a significant amount of work to resolve duplicate prescribed fires (from different sources). This layer is a best attempt, does not include complete data for all agencies. Two of the attributes in this dataset, PRE_CON_CLASS and POST_CON_CLASS are based on an abstract concept called "Condition Class." There is more information about "Condition Class" in the Overview Description / Entity and Attribute Overview section.
Version 22_1 was released in April 2022 and includes 605 fire related fuel treatments from: BLM (14), CAL FIRE (101) and Contract Counties (9), CA State Parks (46), NPS (9), USFS (388), USFW (1), private (6) and other (31) for projects completed in 2022. An additional four 2021 Rx burn perimeters were added from BLM.
Includes input perimeters from CAL FIRE, contract counties, U.S. Forest Service, Bureau of Land Management and National Park Service, California State Parks and other organizations.

This is a reasonably complete digital record of modern fire use history in California. However, it is still incomplete in many respects. Fires may be missing altogether or have missing or incorrect attribute data. Some burns may be missing because historical records were lost or damaged, were too small for the minimum cutoffs, had inadequate documentation or have not yet been incorporated into the database.
Other errors with the fire perimeter database include duplicate fires and over-generalization. The data capture process attempts to identify duplicate fires resulting from multiple data sources (i.e. the USFS and CAL FIRE both captured and submitted the fire perimeter), some duplicates may still exist. Additionally, over-generalization, particularly with large old fires may show unburned "islands" within the final perimeter as burned or where treatment areas were defined but geometry was not modified to account for actual burned area. Users of the fire perimeter database must exercise caution in application of the data. Careful use of the fire perimeter database will prevent users from drawing inaccurate or erroneous conclusions from the data.
