Name:
Polypodium spp. - Umbilicaria spp. - Danthonia spicata Talus, Bluff & Rock Vegetation Group
Reference:
NatureServe Biotics 2019
Description:
This group encompasses sparse vascular or nonvascular vegetation on steep, unconsolidated substrates in temperate eastern North America. The two main substrate types are talus slopes and erosional bluffs. Vegetation varies with substrate character and chemistry. Open talus features sparse vascular vegetation with <i>Dryopteris marginalis, Parthenocissus quinquefolia, Polypodium</i> spp., <i>Ribes</i> spp., <i>Toxicodendron radicans</i>, or <i>Toxicodendron rydbergii</i> characteristic, and/or areas dominated by macrolichens. Characteristic foliose and fruticose macrolichen genera include <i>Umbilicaria, Lasallia, Cladonia</i>, and <i>Stereocaulon</i>. Crustose lichens are also common. Scattered small trees may be present, including <i>Juniperus virginiana</i>. Vegetation on erosional bluffs is sparse and highly variable. Species in these habitats tolerate disturbance, and can include <i>Carex scoparia, Comptonia peregrina, Danthonia spicata, Dichanthelium depauperatum, Equisetum arvense, Equisetum hyemale, Impatiens capensis, Oenothera biennis, Polygonella articulata, Schizachyrium scoparium, Solidago nemoralis</i>, and non-native weeds including <i>Tussilago farfara</i>.
