CEGL005045 Pinus banksiana / Aronia melanocarpa / Xanthoparmelia spp. Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Jack Pine / Black Chokeberry / Boulder Lichen species Woodland
Colloquial Name: Jack Pine Pavement Barrens
Hierarchy Level: Association
Type Concept: This community is found in northern New York and adjacent Canada, where it occurs on very shallow soils over relatively flat sandstone or granite bedrock. The canopy is open, ranging from 10-60%. Pinus banksiana is the typical dominant, although Pinus resinosa, Pinus rigida, and Pinus strobus may be locally dominant. Other characteristic trees include Acer rubrum, Betula papyrifera, and Quercus rubra. The shrub layer is dominated by heath shrubs, including Aronia melanocarpa, Comptonia peregrina, Gaylussacia baccata, and Vaccinium angustifolium. The ground layer includes many lichens and mosses, which may form a continuous mat in some areas. Characteristic lichens include Cladonia spp., Stereocaulon sp., and Xanthoparmelia sp. Characteristic mosses include Polytrichum spp. and Pleurozium schreberi. Herbs are scattered throughout this mat, including Danthonia spicata, Deschampsia flexuosa, Gaultheria procumbens, and Pteridium aquilinum. This community has very few vascular species, and its distinctiveness may be partially a function of the lichen flora.

Classification Comments: This community is related to jack pine woodlands in Maine and New Hampshire and also to acidic rock outcrop communities throughout New England. Excepting the flatrock habitat, similar vegetation may be found in central Ontario. This community, however, is very species-depauperate, and its distinctiveness may be partially a function of the lichen flora. Comparable information is not yet available for many similar types.

Floristics: The dominant tree is generally Pinus banksiana, although Pinus strobus or Pinus resinosa may be locally dominant at some sites. Other characteristic trees include Acer rubrum, Betula papyrifera, Quercus rubra, and Quercus coccinea. The shrub layer is dominated by heaths including Vaccinium angustifolium, Gaylussacia baccata, as well as Aronia melanocarpa and Comptonia peregrina. The ground cover includes several lichens and mosses which may form a continuous cover in some areas. Characteristic lichens include Cladonia spp. (= Cladina spp.), Stereocaulon spp., and Xanthoparmelia spp.; characteristic mosses include Polytrichum spp. and Pleurozium schreberi. Herbs including Pteridium aquilinum, Gaultheria procumbens, Danthonia spicata, and Deschampsia flexuosa are scattered throughout.
Dynamics: No Data Available
Environmental Description: This woodland occurs on very shallow soils over sandstone bedrock. It is best developed where the bedrock forms a nearly level pavement.
Geographic Range: This community is common in Ontario, becoming more restricted to the east where it is reported from northern New York, on Potsdam sandstone near the border with Quebec. A similar type of vegetation occurs on the same bedrock across the border in Quebec, but jack pine is rare or absent, replaced by birch or other pines. A similar type of vegetation occurs on sandstone knobs in the St. Lawrence valley of northern New York and Ontario, but pitch pine is the dominant tree, and jack pine is absent.
