HABITAT TYPES AND PLANT COMMUNITIES : 
Jeffrey pine typically occurs in pure stands along the eastern slope of
the Sierra Nevada.  In the northern Sierra Nevada and into the southern
Cascade Range, it forms more mixed stands with Washoe Pine (Pinus
washoensis), ponderosa pine (P. ponderosa), incense cedar (Libocedrus
decurrens), white fir (Abies concolor), and western juniper (Juniperus 
occidentalis).  Common understory associates in mixed stands include
shinyleaf ceanothus (ceanothus velutinus), greenleaf manzanita
(Arctostaphylos patula), curlleaf mountain-mahogany (Cercocarpus ledifolius), 
and bitterbrush (Purshia tridentata) [1,2,19,33].
