DISTRIBUTION AND OCCURRENCE
SPECIES: Artemisia cana ssp. bolanderi | Bolander Silver Sagebrush 



GENERAL DISTRIBUTION : 
Bolander silver sagebrush has the most western distribution and most
restricted range of the three silver sagebrush subspecies.  It occurs
primarily in the central basins of Oregon south through the Great Basin
areas of eastern California and extreme western Nevada [1,4,26,35].  An
isolated population has been described in the San Bernardino Mountains
of California [1].  Bolander silver sagebrush has also been recorded in
western Idaho [35].

HABITAT TYPES AND PLANT COMMUNITIES : 
Mature stands of Bolander silver sagebrush are indicative of climax
conditions within nonforested communities.  Little identification of
habitat types has been done for communities occupied by this subspecies.
A Bolander silver sagebrush/mat muhly (A. cana ssp. bolanderi/
Muhlenbergia richardsonis) habitat type has been described for Idaho
[10].  These sites generally have a sparse understory dominated by mat
muhly and Baltic rush (Juncus balticus).  Apparently similar sites in
Oregon are characterized by a Nevada bluegrass (Poa nevadensis)
understory.  A silver sagebrush community has also been described for
upland sites surrounding seasonal ponds in California [36].  Bottlebrush
squirreltail (Elymus elymoides) was the herbaceous dominant on these
sites.
