General Hardwood Forests
Montane Mesic Forests with Seepages/Headwater Streams
General Description Members of this habitat include species such as semi-terrestrial salamanders, whose larvae require seeps and headwater streams for development, but whose adults roam widely across the forest floor in search of food and that take shelter under logs or in terrestrial burrows. Also included are species that do the opposite, for example, the American Water Shrew, which den and raise their young on land but that forage primarily in streams or along their edges. All members of this habitat occur almost entirely in the Mountains.

Nr = Number of Ranked Species = 8
Ner = Number of Extant, Ranked Species = 8
Nv = Number of Historic and Extirpated Species = 0
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 7
Nss = Number of Secure Species (State Rank = S5) = 1
Pss = Proportion of Secure Species (Nss/Ner) = 0.12500
ENE = Expected Number of Extirpations (Sum of PE) = 0.35406
Average PE (ENE/Ner) = 0.04426
Habitat Risk Index = (Nar+Nv) x Average PE = 7 x 0.04426 = 0.30982
