Central Maine Foothills biophysical regionThe Central Maine Foothills Biophysical Region is part of the Northeastern Mixed Forest Province and the Maine-New Brunswick Foothills and Lowlands Ecoregion Section. There are 3 Forest Provinces, 6 Ecoregion Sections, and 19 Biophysical Regions in Maine.


Province: Northeastern Mixed Forest

The Northeastern Mixed Forest Province is characterized by a modified continental climatic regime with a maritime influence along the Atlantic Ocean. Winters are moderately long with continual ground snow cover.  Annual precipitation is generally equally distributed with a peak during summer.  Vegetation of this area consists of forests that provide a transition between boreal conifers and broadleaf deciduous.


Ecoregion Section: Maine-New Brunswick Foothills and Lowlands

The Maine-New Brunswick Foothills and Lowlands Ecoregion Section is a glacially scoured and dissected peneplain with gently rolling topography. It is dominated by a broad, central marine plain with other areas of gently sloping hills and low, rounded mountains. Formations are largely sedimentary rocks with areas of intruded igneous granites. Forest vegetation consists of spruce-fir and maple-beech-birch cover types.


Biophysical Region: Central Maine Foothills

The Central Maine Foothills Biophysical Region has a forested percentage of 91% and the most prevalent forest type is maple-beech-birch, with a 45% share of the forestland.

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

  1. Balsam Fir (32 trees per acre)
  2. Northern White Cedar (24 trees per acre)
  3. Red Maple (22 trees per acre) and Red Spruce (21 trees per acre)
