    Description

    Approximately 12.5 percent of California commercial forest land is infested with Heterobasidion annosum, resulting in annual losses of approximately 111 million board feet. The east side of the Sierra Nevada/Cascade Crest in northeastern California is most severely affected, with about 20percent of the land out of production because of annosus root disease. In Yosemite Valley, 158 annosus root disease centers were identified. These centers are enlarging at an average rate of 0.67 m/yr. The most important impact of annosus root disease in recreation areas appears to be hazard and the loss of vegetative cover.
