Name:
Campanula rotundifolia - Packera paupercula - (Aquilegia canadensis) Riverscour Sparse Vegetation
Reference:
NatureServe Biotics 2019
Description:
This sparsely vegetated community is found on outcrops of circumneutral or calcareous rock along rivershores in the northern Appalachian Mountains and perhaps adjacent Canada. Substrates are usually dolomite, limestone, or slate. Most are flooded annually at high water; this helps to maintain open conditions and also provides silt that accumulates in the rock crevices. The annual disturbance pattern of flooding and ice-scour restricts the vegetation to tough crevice-rooting herbs and low shrubs. Total vegetation cover is often less than 20%. Floristic composition can vary considerably, but characteristic species include <i>Campanula rotundifolia, Aquilegia canadensis, Packera paupercula, Allium schoenoprasum var. sibiricum, Carex eburnea, Carex granularis, Erigeron hyssopifolius, Houstonia longifolia, Viola novae-angliae, Lobelia kalmii, Trisetum spicatum</i>, and <i>Dasiphora fruticosa ssp. floribunda</i>. Associated species that are also common in other habitats include <i>Thalictrum pubescens, Solidago bicolor, Antennaria</i> spp., <i>Ionactis linariifolius, Deschampsia cespitosa, Toxicodendron rydbergii, Vaccinium angustifolium, Vaccinium cespitosum, Cornus amomum</i>, and <i>Cornus sericea</i>. <i>Grimmia</i> spp., <i>Tortella tortuosa</i>, and <i>Tortula ruralis</i> are characteristic mosses.
