DISTRIBUTION AND OCCURRENCE
SPECIES: Pinus washoensis | Washoe Pine 



GENERAL DISTRIBUTION : 
Washoe pine occurs in three mountain ranges on the western rim of the
Great Basin in northeastern California and northwestern Nevada [3,4,17].
It occupies a few square miles on the east slopes of Mount Rose, Nevada,
and can be found in small stands in the southern Warner Mountains and in
the Bald Mountain range of northeastern California [3,4].  Isolated
stands have been reported in Oregon and British Columbia [4,16].

HABITAT TYPES AND PLANT COMMUNITIES : 
Washoe pine typically occurs in pure stands at higher elevations along
the eastern slope of the Sierra Nevada.  In the northern Sierra Nevada
and into the southern Cascade Range, it forms mixed stands with Jeffrey
pine, Pacific ponderosa pine, incense cedar (Libocedrus decurrens),
white fir (Abies concolor), California red fir (A. magnifica), and
western juniper (Juniperus occidentalis) [4,10,14,16,21].  Other common
tree associates include sugar pine (Pinus lambertiana) and quaking aspen
(Populus tremuloides var. aurea).  Other associates include mountain
sweetroot (Osmorhiza chilensis), white hawkweed (Hieracium albiflorum),
greenleaf manzanita (Arctostaphylos patula), mountain big sagebrush
(Artemesia tridentata ssp. vaseyana), antelope bitterbrush (Purshia
tridentata), snowbrush ceanothus (Ceanothus velutinus), wooly wyethia
(Wyethia mollis), snowberry (Symphoricarpos vaccinioides), Idaho fescue
(Festuca idahoensis), Wheeler bluegrass (Poa nervosa), and Orcutt brome
(Bromus orcuttianus) [1,10,14,18,20,21].
