Montane Cool Mesic Conifer Forests
No image for this habitat.
General Description This habitat includes cool, moist, montane conifer forests. These include stands of Spruce and Fir at high elevations and stands of Canadian Hemlock forests in cove and alluvial forests at lower elevations.

The trees themselves belong to more specialized habitats and the Determining Species are oligophagous herbivores that make use of Spruce, Fir, and Hemlock but are not specialized on any one of these species.

Nr = Number of Ranked Species = 15
Ner = Number of Extant, Ranked Species = 15
Nv = Number of Historic and Extirpated Species = 0
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 15
Nss = Number of Secure Species (State Rank = S5) = 0
Pss = Proportion of Secure Species (Nss/Ner) = 0.00000
ENE = Expected Number of Extirpations (Sum of PE) = 0.05203
Average PE (ENE/Ner) = 0.00347
Habitat Risk Index = (Nar+Nv) x Average PE = 15 x 0.00347 = 0.05205
