Name: Danthonia spicata Herbaceous Alliance Reference: Eastern Ecology Working Group of... 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.  Accession Code: VB.CC.19111.DANTHONIASPICAT Plot-observations of this Community Concept: 0
