Distinctiveness (1=highest,4=lowest): 1 (globally outstanding)
Top-level predators remain in this ecoregion, which provides important denning sites for brown bears and wolves.  It is an important migration corridor for caribou herds.*

Conservation Status (1=most endangered, 5=most intact): 4 (relatively stable)
Currently this ecoregion is one large, intact block of habitat.  However coal and mineral development in the western half could cause severe and permanent damage.*

Characteristic species*
Eriophorum vaginatum (cottongrass)
Carex bigelowii (Bigelow's sedge)
Betula nana (dwarf birch)
Empetrum nigrum (black crowberry)
Ledum decumbens (Labrador tea)
