Past Fire Activity

In Yosemite, fire records date back to 1930; therefore, Yosemite fire managers have 80 years of records on fire and suppression activities. Tree ring studies provide fire frequency dating back hundreds and thousands of years. This historical information has helped shape goals and objectives for today's fire management program. Scroll down to view a graphic representation of fire activity from 2000-2010. Also, find annual summaries of the 2010, 2009 and 2008 fire seasons, and a prescribed fire history map--detailing four decades of prescribed burns. (Compare to this year's current fire activity.)

 

2014 El Portal Fire

The El Portal Fire started on July 26, 2014, in the community of Old El Portal. Approximately 4,689 acres were burned in the El Portal Administrative Site, Yosemite National Park, and Stanislaus National Forest.

A Burned Area Emergency Response Plan [PDF 11.9 MB] was developed to address post-fire emergency stabilization issues resulting from the El Portal Fire. Additionally, the park engaged two independent engineering firms to conduct sediment/debris studies: El Portal Fire—Sediment/Debris Runoff Mitigation [PDF 1.1 MB] and Summary and Recommendations—El Portal Fire Sediment/Debris Mitigation [PDF 2.5 MB].


 

The Rim Fire
The Rim Fire began August 17, 2013, on the Stanislaus National Forest in the Central Sierra of California and burned over 255,000 acres. Approximately 77,254 acres were in Yosemite National Park.

A Burned Area Emergency Response (BAER) Plan [PDF 11.7 MB] was developed to address post-fire emergency stabilization issues resulting from the Rim Fire.
