Name: A.1281
Reference: EcoArt 2002
Description: This alliance, currently known from the western Great Lakes region and the Appalachian Mountains, is a dry, open grassland on acidic bedrock. In both areas it may result, in part, from clearing and pasturing of montane or boreal forests. It is dominated by herbaceous species, but shrubs and nonvascular species can be abundant. Short grasses, especially ~Danthonia spicata$ and ~Poa compressa$, are most common. ~Carex pensylvanica$ and ~Hieracium$ spp. are also typical. Nearly all shrubs are less than 2 m tall, most are less than 1 m. Common species include ~Amelanchier$ spp., ~Corylus cornuta, Juniperus communis, Rosa$ spp., ~Rhus typhina$, and ~Vaccinium$ spp. Mosses and lichens occur over much of the bedrock outcrops. Stands are found on gentle to moderate slopes over bedrock with shallow soil. Bedrock outcrops are common, and in the Great Lakes region are granite. The combination of sloping sites and thin soil lead to poor water retention and droughty conditions.
