Habitats of North Carolina

Conifer Forests
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.
