Name: Acer spicatum - Thuja occidentalis - Betula papyrifera / Taxus canadensis Shrubland
Reference: Midwestern Ecology Working Group...
Description: This boreal cliff forest is found in the boreal regions of the midwestern United States and in adjacent Canada. At Isle Royale National Park in Michigan, this community occupies sites on very steep talus slopes or cliffs, typically facing northwest, and thus is relatively moist. Bedrock is igneous/metamorphic and may be either granite or basalt/diabase. The vegetation forms a closed canopy forested scrub, with about 80% canopy cover. Acer spicatum is dominant in the canopy, with over 50% cover; other tree species present include Thuja occidentalis, Betula papyrifera, and Picea glauca. There is about 30% cover of short shrubs; Taxus canadensis and Rubus parviflorus are the most abundant shrubs. Cover of herbs is about 30%; the most abundant herbs are Gymnocarpium dryopteris and Mitella nuda. Cover of nonvascular plants is about 20%; Pleurozium schreberi is a common moss.
