Acadian-Appalachian Alpine Tundra Macrogroup: Alpine yourStateNatural Heritage Ecologist for more information about this habitat. This is modeledmap a distributiononbased current and is data nota substitute for field inventory. based Contact © Josh Royte (The Nature Conservancy, Maine) Description: A sparsely vegetated system near or above treeline in the Northern Appalachian Mountains, dominated by lichens, dwarf-shrubland, and sedges. At the highest elevations, the dominant plants are dwarf heaths such as alpine bilberry and cushion-plants such as diapensia. Bigelow’s sedge is characteristic. Wetland depressions, such as small alpine bogs and rare sloping fens, may be found within the surrounding upland matrix. In the lower subalpine zone, deciduous shrubs such as nannyberry provide cover in somewhat protected areas; dwarf heaths including crowberry, Labrador tea, sheep laurel, and lowbush blueberry, are typical. Nearer treeline, spruce and fir that State Distribution: ME, NH, NY, VT have become progressively more stunted as exposure increases may form nearly impenetrable krummholz.

This is modeledmap a distributiononbased current and is data nota substitute for field inventory. based Contact © Andy Cutco (Maine Natural Areas Program) Description: A conifer or mixed forest forming extensive flats on areas of imperfectly drained soils. Black spruce, red spruce, and balsam fir dominate a mostly closed canopy; yellow birch, hemlock, black cherry, and red maple are sometimes present in smaller numbers. Bryophytes and low herbs are abundant in the ground layer; the shrub layers are typically sparse and made up principally of heath species. This forest is characteristic of colder regions of the northern Appalachians-Acadian region, where it often forms long narrow patches along riverside flats in valley bottoms.
