Distinctiveness (1=highest,4=lowest): 3 (bioregionally outstanding)
Riparian areas are important habitat for fish and for wildlife using them as corridors.  Old-growth forests serve as refugia for many bird species.*

Conservation Status (1=most endangered, 5=most intact): 3 (vulnerable)
Approximately 10% of habitat remains intact.  Fire suppression and logging has degraded ponderosa pine forests.  Overgrazing is a serious threat to non-forested areas.*

Characteristic species*
Artemisia tridentata (big sagebrush)
Juniperus occidentalis
Pinus ponderosa (ponderosa pine)
Pseudotsuga menziesii
 (Douglas fir)
Larix occidentalis  (western larch)

Picea spp.
