Name: Lasallia papulosa - Lasallia caroliniana Nonvascular Vegetation
Reference: NatureServe Biotics 2019
Description: This association is known from the steeply sloping exfoliation dome faces on Grandfather Mountain, North Carolina, and probably at Roan Mountain, Tennessee and North Carolina. As defined, this association and its alliance are intended to cover vertical cliffs and sometimes more gently sloping large outcrops (often as large as 1 hectare) which have extremely few or no vascular plants and are relatively dry. In the Southern Appalachians, these generally occur because of a combination of outcrop geometry (few or no suitable crevices, as in exfoliation domes) and hydrology (inadequate seepage moisture to support vascular plants). A few crevice vascular plants are allowed. Moister cliffs without crevices support ~<i>Umbilicaria mammulata</i> Cliff Vegetation (CEGL004387)$$.
