General Hardwood Forests
Montane Mesic Forests with Seepages/Headwater Streams
Habitat Overview 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.


Related NHP Natural Communities Most of the seepage communities used by this habitat group are small and probably best fit the Low Elevation Seep (Piedmont/Mountain Springhead Subtype) NHP community type. Other communities that are larger, more open, and more closely akin to montane bogs may also be used, including High Elevation Boggy Seep, Rich Montane Seep, and Low Elevation Seep (Typic, Montane, and Floodplain Subtypes). Mesic forest communities used by the adults of this group include: Northern Hardwood Forest, High Elevation Birch Boulderfield Forest, Rich Cove Forest, Acidic Cove Forest, and Canada Hemlock Forest.

Candidates for Inclusion Crayfish and other invertebrates associated with montane seeps can be included in this habitat type once websites have been developed for their taxa

Average Imperilment of Habitat Members
Habitat Conservation Status The average Imperilment Score for this habitat group is 4.02, roughly corresponding to an NHP rank of G5 S1S2, i.e., of no conservation significance at the global level but of high significance at the state level. However, two of the five members of this habitat are ranked as G3, indicating at least a minimum level of significance at the global level. Conversely, none of the members have a high level state rank, although four of the five have a state rank of S3, a moderate level of significance at the state level.
