The UC Santa Barbara's Valentine Eastern Sierra Reserves (Reserve) is proposing to reduce hazardous fuels on 50 acres of the 154-acre Valentine Camp Reserve, a unit of the University of California's Natural Reserve System. Valentine Camp Reserve sits at the urban/wildland interface between the Town of Mammoth Lakes, CA, a resort community with very high property values, and the Inyo National Forest. The purpose of this project is to reduce potential future wildfire severity, improve forest health and protect developed infrastructure in the Town of Mammoth Lakes, and research/educational facilities within the Reserve in the wildland-urban interface. Valentine Reserve has not experienced a fire in over 170 years. Before this time, average fire recurrence intervals ranged from 15-25 years depending on the slope and aspect. As a result of fire suppression, forest health has deteriorated, forest density is unnaturally high, and fuel loading is very high. From a detailed fire history of the site, historic fire recurrence intervals were ~20 years depending on aspect. Forest density is as high as 900/stems/acre which is very, very high for Eastern Sierra Nevada mixed conifer (activity) surface fuels during fuels reduction operations. The Valentine Reserve is surrounded by the Town of Mammoth Lakes, which has a full time population of approx 8,300 and a peak population of 40,000 people in approx 12,000 unites/homes. Mammoth Lakes is zoned with commercial, high and low density residential, industrial, institutional public, resort, national forest and open space zones. Immediately bordering Valentine Camp Reserve, there are approx 500 habitable structures in the Juniper Springs Resort Development, and adjacent areas. The beneficiaries of this project include the research and educational users of the UC Valentine Eastern Sierra Reserves, Town of Mammoth Lakes, the Inyo National Forest and the Mammoth Lakes Basin, which is a very high use recreation area, southwest of the Town of Mammoth Lakes.
