Name: Dasiphora fruticosa ssp. floribunda / Clinopodium arkansanum - Argentina anserina - Primula mistassinica Sparse Vegetation
Reference: Midwestern Ecology Working Group...
Description: This community occurs along Great Lakes shores of the United States and Canada where broad, flat, horizontally bedded limestone or dolostone are exposed along or near the shoreline. Limestone cobble may be present. These lakeshores are characterized by a zonal gradation of plant communities, changing in response to distance from the lake. The width of the zone varies with fluctuations in the Great Lakes water level. The splash/scrape zone, which averages 10 m in width, is very sparsely vegetated, with small pools of standing water. Plant species are typically found in protected bedrock cracks. Typical species in this zone include <i>Juncus balticus, Argentina anserina (= Potentilla anserina)</i>, and <i>Populus balsamifera</i>. The vegetated zone occurs more inland as soil accumulates in and adjacent to bedrock cracks. Vegetation is still patchy. Common species include <i>Clinopodium arkansanum (= Calamintha arkansana), Deschampsia caespitosa, Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda), Dichanthelium acuminatum var. lindheimeri (= Panicum lindheimeri)</i>, and species from the previous zone. A variety of mosses, including <i>Campylium stellatum</i>, are common throughout this zone. Further inland, sand accumulations or cobble ridges on the bedrock surface provide a suitable substrate for the establishment of woody and herbaceous plants. Scattered trees and shrubs are common, including <i>Abies balsamea, Picea glauca, Populus balsamifera</i>, and <i>Thuja occidentalis</i>.
