Starting Wednesday, November 3rd, fire crews will be prescribed burning units 11 & 16 in Yosemite Valley. This is a continuation of burns conducted a week ago. Unit 11 is located south of Southside Drive near the El Capitan Crossover and Unit 16 is located between Southside Drive and the Four Mile trailhead. Ignitions will occur over the next few days. There will be trail closures in Yosemite Valley, including the Valley Loop Trail from the Four Mile trailhead to the El Captain crossover road along Southside Drive. Prescribed burn units have been carefully designed to meet multiple objectives; the objectives of this prescribed burn are to restore and maintain plant communities shaped by Native Americans, restore fire and a more natural ecosystem structure to communities, maintain meadows and healthy stands of conifers, reduce hazardous fuels, and provide protection to infrastructure. Each prescribed burn unit has defined weather parameters and firing patterns to ensure the objectives for each unit have a high potential for success. Yosemite fire and resources staff will monitor all prescribed burns to evaluate achievement of goals and help guide future prescriptions.
Visitors and employees should be aware that smoke may be present starting Wednesday and could linger to a much lesser degree into next week as large logs are consumed. Fire managers work closely with Park staff and the local air pollution control districts to time the prescribed burns to coincide with favorable weather and smoke dispersion conditions. Smoke impacts are always a consideration in the decision to begin any prescribed burning operation. Burning will only be conducted under favorable dispersal conditions as specified in the smoke permit.
