Name: Polypodium (virginianum, appalachianum) / Lichens Nonvascular Vegetation
Reference: Eastern Ecology Working Group of...
Description: This sparsely vegetated, open talus slope of the northern Appalachian Mountains region is characterized by large boulder talus dominated by lichen cover. Soil is confined to shallow accumulations in rock pockets, and higher plant growth is limited by both lack of nutrients and dry conditions. Little data are available on the dominant lichens, but they can include Umbilicaria spp, as well as other common foliose and crustose species. Vascular plants are a variable mix of scattered individuals of Picea rubens, Betula papyrifera var. cordifolia, Betula papyrifera var. papyrifera, Betula alleghaniensis, Acer spicatum, Sorbus americana and/or Sorbus decora, Polypodium virginianum, Polypodium appalachianum, Deschampsia flexuosa, and Parthenocissus quinquefolia. In more southern examples of this community, Betula populifolia, Tsuga canadensis, Ostrya virginiana, Juniperus virginiana, and Quercus rubra may be present. The community provides denning sites for small mammals and snakes.
