Name: Picea mariana - Populus tremuloides / Mixed Herbs Forest Reference: NatureServe Biotics 2019 Description: This black spruce - aspen forest community type is found in the boreal regions of east-central Canada. Stands occur on flat to gently sloping sites with fresh to moist mineral soils. Soil texture is most often coarse loam, but can be clay, silt, or sand. In Ontario, this community often occurs on calcareous soil. The tree layer is dominated by a moderately closed to closed canopy of mixed coniferous and deciduous species. <i>Populus tremuloides</i> is the only common deciduous tree, but scattered <i>Betula papyrifera</i> and <i>Populus balsamifera</i> are also found. <i>Picea mariana</i> is the most abundant coniferous species, and often the most abundant canopy species. <i>Abies balsamea, Picea glauca</i>, and <i>Pinus banksiana</i> are typical associated conifers. The shrub layer ranges from open to dense. Species found in this layer include <i>Diervilla lonicera, Ledum groenlandicum, Linnaea borealis, Rosa acicularis, Rubus pubescens, Vaccinium angustifolium</i>, and <i>Vaccinium myrtilloides</i>. The herbaceous layer has great diversity. <i>Aralia nudicaulis, Eurybia macrophylla, Cornus canadensis, Coptis trifolia, Maianthemum canadense, Petasites frigidus, Trientalis borealis</i>, and <i>Viola renifolia</i> are common herbaceous species. Mosses also cover a substantial portion of the forest floor.  Accession Code: urn:lsid:vegbank.org:commConcept:31424-{E681A404-EF5A-41F5-A3F5-8FC2574FF930} Plot-observations of this Community Concept: 32
