Download M211-Adirondack-New England Mixed Forest

Description of Ecological Subregions: Sections of the Conterminous United States
mineral content. Forest vegetation was largely aspen-birch and white-red-jack pine cover types.
M211-Adirondack-New England Mixed ForestConiferous Forest-Alpine Meadow Province
This 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.
M211A-White Mountains Section
This 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. (Photo:

M211B-New England Piedmont Section
This section is a maturely dissected peneplain with open, low mountains and monadnocks. Rocks are
mainly quartzite, slate, and schist with large areas of gneiss metamorphics and a belt of volcanics. Forest
vegetation consists of maple-beech-birch and aspen-birch cover types.
M211C-Green, Taconic, Berkshire Mountains Section
The landscape was previously glaciated mountain ranges that resulted
in areas ranging from nearly flat-topped plateaus with scattered
monadnocks to sharp ridges with deep valleys. Geologic formations
include quartzite, schist, metavolcanics, gneiss, and amphibolite.
Vegetation is forests of maple-beech-birch and aspen-birch cover
types. (Photo: Staff, USDA Forest Service)
M211D-Adirondack Highlands Section
This subregion is a dissected, asymmetrical dome that has weathered to
form mountainous terrain with rolling hills; relief is locally steep.
Rocks under highest mountains consist of metanorthsite with mixed
gneisses under the hills; sandstones are present in localized areas.
Forest vegetation consists of maple-beech-birch, aspen-birch, and oakhickory cover types. (Photo: USDA Natural Resources Conservation
