June 4, 2021 - Sacramento - For the 21st consecutive year, CAL FIRE’s Fire and Resource Assessment Program has collected and made available to the public, spatial records of the perimeters of wildfires and prescribed fires in California. This data contains 500 fires and covers over 97 percent of the acres burned in 2020.

This data is used for a wide variety of products by fire and habitat managers, academia, home owners, media, the insurance, and power supply industry. CAL FIRE uses this information for:

• As input in fire effects analysis
• Analysis of drivers of fire occurrence
• Evaluation of fuel treatment effectiveness
• Estimating spatially explicit burn probability for use in hazard assessment updates to CAL FIRE fuel data layers for spread prediction and risk assessment

This dataset is only possible because of a long-standing partnership with USFS, BLM and National Park Service. The data can be downloaded here: https://frap.fire.ca.gov/frap-projects/fire-perimeters/ or here https://frap.fire.ca.gov/mapping/gis-data/.
