Name: Picea glauca Woodland Alliance Reference: Midwestern Ecology Working Group... Description: This alliance, found in northern Michigan and northwestern Ontario, occurs on rocky ridges and hills. The discontinuous tree canopy is dominated by Picea glauca, sometimes with Betula papyrifera codominant. Populus tremuloides can be present, as well. The trees are relatively short, typically under 13 m tall. Shrubs under 2 m tall are often abundant. Amelanchier spp., Corylus cornuta, Prunus virginiana, Rhus spp., and Rosa spp. are common shrubs. The herbaceous layer is dominated by graminoids, especially Danthonia spicata. Poa spp. and Hieracium spp. can be found, especially in disturbed stands. Lichens and mosses are also abundant. Stands of this alliance are found on hilltops and ridges with thin soils. Slope and aspect are variable, but most stands are on gentle to moderate slopes. Exposed bedrock is common.  Accession Code: VB.CC.19577.PICEAGLAUCAWOOD Plot-observations of this Community Concept: 0
