Name: Betula alleghaniensis - (Acer saccharum, Picea glauca) Forest Reference: NatureServe Biotics 2019 Description: This yellow birch forest type is provisionally reported from Isle Royale, Michigan, but its rangewide status is still unclear. It may extend to the east, until <i>Picea rubens</i> enters into the range. At Isle Royale National Park, this community occupies gentle to steep slopes at elevations from 190-240 m (630-780 feet). Soils are moderately well-drained to rapidly drained sandy loams. The vegetation forms a closed-canopy, deciduous forest. Canopy cover is usually about 70-80% cover (sometimes less); the most abundant trees are <i>Betula alleghaniensis, Picea glauca</i> and <i>Betula papyrifera</i>. There is often a subcanopy with 5-30% cover (same species as in the canopy). Cover of tall shrubs is about 5-10% cover; the most abundant tall shrubs are saplings of <i>Picea glauca</i> and <i>Abies balsamea</i>, and <i>Sambucus racemosa</i>. Cover of short shrubs varies from 10-70% cover; the most abundant short shrubs are <i>Rubus parviflorus, Sorbus decora, Diervilla lonicera, Lonicera canadensis</i>, and <i>Rubus idaeus</i>. There is a sparse cover of dwarf-shrubs, mainly <i>Rubus pubescens</i>. Cover of herbs varies from 40-80% cover; the most abundant herbs are <i>Aralia nudicaulis, Cornus canadensis, Clintonia borealis, Lycopodium annotinum, Streptopus lanceolatus var. roseus, Athyrium filix-femina</i>, and <i>Oxalis montana</i>. Cover of nonvascular plants is sparse (0-10% cover); <i>Pleurozium schreberi</i> is characteristic.  Accession Code: urn:lsid:vegbank.org:commConcept:34008-{E935EC63-D4E6-42F9-8329-DB3E671E729E} Plot-observations of this Community Concept: 0
