Sandstone Pavement Barrens

New York State Distribution [-]
This community is a narrow regional endemic that is possibly restricted to the northernmost counties of New York, north of the Adirondack Mountains in the northeastern portion of the Great Lakes Ecoregion, where the bedrock is sandstone. It is concentrated in the Champlain Valley of Clinton and Essex Counties where it reaches large patch size. Several small patch occurrences are reported from the Eastern Ontario and St. Lawrence Lowlands including islands in the Thousand Islands Region. Additional occurrences are suspected from within Lake George.

Global Distribution [-]
This community is possibly restricted to the northeastern portion of the Great Lakes basin and parts of Maine. It may extend into northern and central Canada. The narrowly defined jack pine (Pinus banksiana) dominated barrens are known from northeastern New York, southern Quebec and Maine. Similar communities may also occur in Ontario, Minnesota, and Iowa.
