CEGL004980 Asplenium montanum - Heuchera villosa Felsic Cliff Vegetation

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Mountain Spleenwort - Hairy Alumroot Felsic Cliff Vegetation

Colloquial Name: Appalachian Felsic Cliff

Hierarchy Level:  Association

Type Concept: This community occurs in the Blue Ridge and upper Piedmont of Georgia, North Carolina, South Carolina, Tennessee, and Virginia. It includes vertical rock faces associated with felsic, metamorphic and igneous geologies. This community generally has little vegetative cover, often with 90% of the rock surface unvegetated. Mosses (e.g., Thuidium spp., Fissidens spp., Campylium sp., Bryoandersonia sp., Plagiomnium sp.) and lichens can have moderate coverage, and vascular plants occur on ledges and rooted in cracks. Asplenium montanum and Heuchera villosa are characteristic components. Other typical species include Agrostis perennans, Arisaema triphyllum, Aristolochia macrophylla, Asplenium trichomanes, Eurybia divaricata, Cystopteris protrusa, Dryopteris marginalis, Hydrangea arborescens, Parthenocissus quinquefolia, Polypodium appalachianum, and Rubus canadensis. These cliffs are typically dry, although small seepages may occur. They are usually shaded by trees rooted on ledges and by the surrounding forest.

Floristics: This community has little vegetative cover, often with 90% of the rock surface unvegetated. Mosses (e.g., Thuidium spp., Fissidens spp., Campylium sp., Bryoandersonia sp., Plagiomnium sp.) and lichens can have moderate coverage, and vascular plants occur on ledges and rooted in cracks. Asplenium montanum and Heuchera villosa are characteristic components. Other typical species include Agrostis perennans, Arisaema triphyllum, Aristolochia macrophylla, Asplenium trichomanes, Eurybia divaricata (= Aster divaricatus), Cystopteris protrusa, Dryopteris marginalis, Hydrangea arborescens, Parthenocissus quinquefolia, Polypodium appalachianum, and Rubus canadensis. An example of a shaded rock outcrop from the Chattahoochee National Forest (Georgia) which is assigned here contains low coverages of the woody plants Hydrangea arborescens, Kalmia latifolia, Vaccinium arboreum, and Vaccinium simulatum, along with the herbs Campanula divaricata, Dryopteris marginalis, Galax urceolata, Iris cristata, Muhlenbergia tenuiflora, Polygonatum biflorum, Silene stellata, and Solidago sphacelata. An example in Great Smoky Mountains National Park (Tennessee) consisted of Heuchera villosa, Pilea pumila, Impatiens pallida, Sedum ternatum, and various moss species but did not contain Asplenium montanum.

Dynamics:  These cliffs are typically dry, although small seepages may occur. They are usually shaded by trees rooted on ledges and by the surrounding forest.

Environmental Description:  This community includes vertical rock faces associated with felsic, metamorphic and igneous geologies. Some occurrences attributed to this type appear to be on subcalcareous substrates. These cliffs are typically dry, although small seepages may occur. They are usually shaded by trees rooted on ledges and by the surrounding forest.

Geographic Range: This community occurs in the Blue Ridge and upper Piedmont of Georgia, North Carolina, South Carolina, Tennessee, and Virginia.
