Red fir (Abies magnifica) dominates large areas of high country that are a major source of water, especially in California. For this reason it has long been an important forest tree. Only recently has red fir assumed significance as an unusually productive source of wood (17). Relatively little detailed, coherent silvical information is available, however.
North of Mount Lassen in northern California, red fir shows morphological and perhaps ecological characteristics that have led to its common designation as Shasta red fir (A. magnifica var. shastensis) (8,9,22). Here, the varieties are referred to collectively as red fir and are identified only when differences warrant.
