Name: Tsuga canadensis - Fraxinus nigra / Carex bromoides - Geum rivale Forest [Provisional] Reference: Eastern Ecology Working Group of... Description: This is a northern hardwood - conifer seepage forest of central New England. They typically occur in basins or along streamsides that are associated with groundwater discharge or seeps at the wetland margin. They often form at stream headwaters. Soil substrate is well-decomposed peat of variable thickness, ranging from 1-15 feet thick. The canopy is dominated by Acer rubrum or codominated with Fraxinus nigra, which is generally indicative of mineral enrichment from ground water in this region. Other canopy associates include Betula alleghaniensis, Tsuga canadensis, Pinus strobus, and Ulmus americana. The shrub layer includes saplings of canopy tree species plus Rhamnus alnifolia, Vaccinium corymbosum, Ilex verticillata, and Toxicodendron radicans. In the southern extent of the range, Toxicodendron vernix and Lindera benzoin become more abundant. Common herbs include Onoclea sensibilis, Osmunda cinnamomea, Impatiens capensis, Chrysosplenium americanum, Mitella nuda, Saxifraga pensylvanica, Geum rivale, Tiarella cordifolia, Carex leptalea, Carex interior, Glyceria striata, and Dryopteris cristata. Nonvascular layer is usually well-developed and includes Thuidium delicatulum, Rhytidiadelphus triquetrus, and Climacium dendroides with Calliergon cordifolium in hollows.  Accession Code: VB.CC.18812.TSUGACANADENSIS Plot-observations of this Community Concept: 0
