In the Coast Ranges, it is distributed from southwest Trinity County south to Monterey County. In the Cascade-Sierra Nevada foothills, it is distributed from Shasta County south to Tulare County [8]. Although not rare, it is not an abundant species. Local occurrence is widely scattered throughout its range [3], and trees are often infrequent in these localities [8].
