Description:
This basalt bedrock shore community is found along the Lake Superior shorelines of the United States and Canada. Stands occur between the open basalt bedrock and the inland forests. Soils are thin and exposed areas of bedrock are common. This community consists of scattered, open-grown trees, scattered shrubs or shrub thickets, and a partial layer of graminoids, mosses, and lichens. The scattered, and often stunted, tree layer contains <i>Abies balsamea, Betula papyrifera, Picea glauca, Pinus resinosa, Pinus strobus, Quercus rubra, Sorbus decora</i>, and <i>Thuja occidentalis</i>. The shrub layer is very sparse and may contain <i>Amelanchier</i> spp. and <i>Juniperus communis</i>. More prominent is the dwarf-shrub layer, which contains <i>Arctostaphylos uva-ursi, Epigaea repens, Juniperus horizontalis, Lonicera dioica, Rosa acicularis</i>, and <i>Vaccinium angustifolium</i>. The herbaceous layer is characterized by <i>Achillea millefolium, Calamagrostis canadensis, Danthonia spicata, Festuca saximontana var. saximontana, Fragaria virginiana</i>, and <i>Sibbaldiopsis tridentata</i>. Mosses and lichens occur in localized patches throughout the stand.
