click to update datacart
Name: Picea mariana / Kalmia angustifolia Woodland Reference: NatureServe Biotics 2019 Description: This black spruce woodland of east coastal Maine and adjacent maritime Canada occurs on rock outcrops and headlands. Soils are acidic, thin and patchy, composed of organic duff over sand or loam, with exposed bedrock common. The open and stunted tree canopy overlies a well-developed dwarf-shrub layer. (Rarely, the canopy may be more closed, up to 85% cover.) A few taller shrubs or small trees may be present. The herb layer is sparse, and the bryoid layer is patchy and may be locally extensive, with prominent reindeer lichens. The canopy is strongly dominated by <i>Picea mariana</i>, with occasional associates including <i>Picea rubens, Pinus strobus</i>, or <i>Abies balsamea</i>. The dwarf-shrub layer is characterized by <i>Kalmia angustifolia, Vaccinium angustifolium</i>, and <i>Gaylussacia baccata</i> with other associates including <i>Picea mariana</i> and <i>Aronia melanocarpa</i>. Other dwarf-shrubs may include <i>Empetrum nigrum, Vaccinium vitis-idaea, Gaultheria hispidula</i>, or <i>Morella pensylvanica</i>. The herbaceous layer is composed mostly of <i>Pteridium aquilinum</i> and <i>Cornus canadensis</i>. The bryophyte layer is characterized by <i>Cladonia</i> lichens as well as <i>Pleurozium schreberi, Polytrichum commune, Dicranum polysetum</i>, and <i>Leucobryum glaucum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:34939-{49B532DF-9DDD-41A3-989C-4AD46862A399} Plot-observations of this Community Concept: 5
