Name:
(Pinus strobus, Quercus rubra) / Danthonia spicata Acid Bedrock Wooded Herbaceous Vegetation
Reference:
Midwestern Ecology Working Group...
Description:
This acid bedrock glade and woodland occurs in the Upper Great Lakes region of the United States and Canada and in northern New England. In the Great Lakes, these glades occupy upper portions above the granitic bedrock shorelines; elsewhere in the Great Lakes and New England they are found on rocky openings. Shrubs and scattered trees dominate the woody canopy layers; tree canopy may grade into woodland physiognomy. Trees include Betula papyrifera, Pinus resinosa, Pinus strobus, and Quercus rubra; in the Great Lakes region, Pinus banksiana is also common. The shrub layer contains Diervilla lonicera, Juniperus communis, and, less frequently, Physocarpus opulifolius (the latter only in the Great Lakes region). The dwarf-shrub Arctostaphylos uva-ursi may also be present. The herbaceous layer contains Agrostis hyemalis, Campanula rotundifolia, Danthonia spicata, Deschampsia caespitosa, Chamerion angustifolium (= Epilobium angustifolium), Poa compressa, Sibbaldiopsis tridentata (= Potentilla tridentata), and Vaccinium angustifolium. Moss and lichen cover may be substantial. In New England a similar composition is found, but Deschampsia flexuosa replaces Deschampsia caespitosa, and the common shrubs are Arctostaphylos uva-ursi, Comptonia peregrina, Gaultheria procumbens, Gaylussacia baccata, Juniperus communis, Kalmia angustifolia, and Vaccinium angustifolium. Picea rubens is occasionally present, and Pinus strobus often absent in montane settings. Common herbaceous species include Maianthemum canadense, Melampyrum lineare, Oryzopsis asperifolia, Pteridium aquilinum, and Trientalis borealis.
