SPECIES: Torreya californica | California Torreya 



GENERAL DISTRIBUTION : 
California torreya is endemic to California.  Its range has two distinct
parts:  one in the Coast Ranges and one in the Cascade-Sierra Nevada
foothills.  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].

many diverse plant communities.  In the Coast Ranges, it grows in
chaparral and various coastal forests such as redwood (Sequoia
sempervirens).  It is associated with canyon live oak (Quercus
chrysolepis) and California bay (Umbellularia californica) woodlands in
both coastal and inland foothill regions [10].  Inland populations are
most commonly found in the ponderosa pine (Pinus ponderosa) belt [3,8].
It is rare in chaparral communities of the Cascade-Sierra Nevada.  It is
not a dominant or indicator species in community or vegetation typings.
