Western Maine Foothills biophysical regionThe Western Maine Foothills Biophysical Region is part of the Adirondack-New England Mixed Forest-Coniferous Forest-Alpine Meadow Province and the White Mountains Ecoregion Section. There are 3 Forest Provinces, 6 Ecoregion Sections, and 19 Biophysical Regions in Maine.


Province: Adirondack-New England Mixed Forest-Coniferous Forest-Alpine Meadow

The Adirondack-New England Mixed Forest-Coniferous Forest-Alpine Meadow Province has a modified continental climatic regime with long, cold winters and warm summers. Annual precipitation evenly distributed. Landscape is mountainous and was previously glaciated. Forest vegetation is a transition between boreal on the north and broadleaf deciduous to the south.


Ecoregion Section: White Mountains

The White Mountains Section has a maturely dissected, irregular highland characterized by clusters of low, rounded mountains and scattered monadnocks with many glacial features. Rock formations include sedimentary quartzite, slate, and schist with extensive area of igneous rocks including granites, diorite, gabbro, and basalt. Forest vegetation consists of spruce-fir, maple-beech-birch, and aspen-birch cover types.


Biophysical Region: Western Maine Foothills

The Western Maine Foothills Biophysical Region has a forested percentage of 86%, and at 62%, maple-beech-birch is the most prevalent forest type.

The top three tree species in this region (based on the stocking of live trees per average forested acre) are:

  1. Red Maple (43 trees per acre)
  2. Eastern Hemlock (22 trees per acre)
  3. Balsam Fir (20 trees per acre)
