CEGL006429 Drosera rotundifolia - Viola spp. Cliff Sparse Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Roundleaf Sundew - Violet species Cliff Sparse Vegetation
Colloquial Name: Northern Appalachian Cliff Seep
Hierarchy Level: Association
Type Concept: This vegetation develops on cliff faces where seepage or other water maintains wet conditions over a large area. Vascular plants are sparse overall although they may be locally abundant; bryophytes are often abundant. Because mineral composition of the substrate can differ over small distances, nutrient regime (including pH) and species composition can vary across the cliff. Typical species of more acidic areas include Viola cucullata, Viola macloskeyi ssp. pallens, Oclemena acuminata, Drosera rotundifolia, Chrysosplenium americanum, Cinna latifolia, and Rubus pubescens. In areas of higher pH, calciphiles such as Dasiphora fruticosa ssp. floribunda, Saxifraga virginiensis, Cystopteris bulbifera, and Packera schweinitziana can occur. These cliff seeps of the northeastern U.S. have been poorly studied and may encompass more than one association.

Floristics: Vascular plants are sparse overall although they may be locally abundant; bryophytes are often abundant. Because mineral composition of the substrate can differ over small distances, nutrient regime (including pH) and species composition can vary across the cliff. Typical species of more acidic areas include Viola cucullata, Viola macloskeyi ssp. pallens, Oclemena acuminata (= Aster acuminatus), Drosera rotundifolia, Chrysosplenium americanum, Cinna latifolia, and Rubus pubescens. In areas of higher pH, calciphiles such as Dasiphora fruticosa ssp. floribunda, Saxifraga virginiensis, Cystopteris bulbifera, and Packera schweinitziana (= Senecio robbinsii) can occur.
Dynamics: No Data Available
Environmental Description: Vertical or near-vertical cliff faces kept wet by interstitial water emerging from the rock face or, in some cases, by flow from above. The protected and wet setting creates a cool microclimate.
Geographic Range: These cliff seeps are known from the northeastern U.S., but are poorly documented. Additional data are needed to clarify the range.
