Distinctiveness (1=highest,4=lowest): 3 (bioregionally
outstanding)
The ecoregion contains a variety of vegetation communities. Large
carnivores, including Canus lupus (wolf) and Ursus arctos (grizzly
bear) are present. *
Conservation Status (1=most endangered, 5=most
intact): 3 (vulnerable)
There are a substantial number of protected areas, such as national parks and
wilderness areas. However, Fragmentation by transportation corridors may
reduce the viability of the ecoregions large carnovires. Mining and
logging are also threats.*
