As of October 2nd, Yosemite has had 50 fires started by lightning and 12 human-caused fires for the 2021 calendar year. The park is utilizing a mix of strategies to suppress, monitor, or contain these fires throughout Yosemite's fire-adapted ecosystems. Currently there are three active fires, two have been contained, one is in the process of being contained using control lines and natural barriers. Smoke from Regional fires may be seen throughout Yosemite.
Fire management actions have adhered to Minimum Impact Suppression Techniques (MIST). This minimizes impacts in the wilderness while allowing the healthy ecological effects of natural fire. The overall strategy for managing all wildland fires is to provide for the safety of employees and the public and protect and enhance natural and cultural resources.
As weather conditions change, fire managers are planning for fall prescribed burns in various locations within Yosemite NP. Additional information with location and dates will be released soon.
