Distinctiveness (1=highest,4=lowest): 4 (nationally important)
This ecoregion has an unusual association of plant communities because of the juxtaposition of boreal forests with one of the most northerly grassland communities.  It supports large mammals as well as top-level predators.*

Conservation Status (1=most endangered, 5=most intact): 3 (vulnerable)
About 75% of this ecoregion remains intact. Habitat loss has resulted from forestry, mining, transportation corridors, and urbanization around Whitehorse.*

Picea mariana (black spruce)
Pinus contorta  (lodgepole pine)
