FORECO Daily: Disturbance happens.


Thin vegetation mats grow in shallow depressions on granitic dome communities south of the Asheville basin. Soil accumulates in shallow depressions, collecting rainwater and providing habitat for spikemosses like Selaginella tortipela. Over time, soil and nutrients accumulate, and grasses and shrubs gain a foothold. These are fragile communities, at ricsk from trampling, ice, and flooding. Here on Little Green, a sizeable mat has torn off, rolling up like sod or shag carpet and leaving the depression bare and exposed where succession will start anew. This cycle of succession and disturbance keeps these granite domes open.
