Fraxinus nigra - Mixed Hardwoods - Conifers / Cornus sericea / Carex spp. Forest
Reference:
Midwestern Ecology Working Group...
Description:
This black ash - mixed hardwoods and conifer swamp forest is found widely in the northern midwestern region of the United States and into the hemi-boreal region of central Canada. Sites are found on well-decomposed woody peat or fine mineral soil. The type is found where perched wet pockets occur on fine sandy, clay loamy to fine loamy soils in valleys with impeded drainage or near shores. Hydrology can vary from seasonally flooded to saturated. Conditions are often transitional to uplands. Canopy structure is variable, ranging from 30-90% cover. The canopy is dominated by <i>Fraxinus nigra</i> (at least 50% cover), with a diverse mix of hardwoods and conifers in the main and subcanopies, including <i>Abies balsamea, Acer rubrum, Betula papyrifera, Betula alleghaniensis, Fraxinus pennsylvanica, Picea glauca, Populus balsamifera, Populus tremuloides, Thuja occidentalis, Tilia americana</i>, and <i>Ulmus americana</i>. Shrub and sapling species include <i>Abies balsamea, Acer spicatum, Cornus sericea, Corylus cornuta, Lonicera canadensis, Prunus virginiana, Ribes triste, Rubus idaeus</i>, and <i>Rubus pubescens</i>. Herbaceous species include <i>Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Athyrium filix-femina, Carex gracillima, Carex intumescens, Cinna latifolia, Circaea alpina, Clintonia borealis, Dryopteris carthusiana, Equisetum sylvaticum, Fragaria virginiana, Maianthemum canadense, Mitella nuda, Streptopus lanceolatus var. longipes (= Streptopus roseus), Thalictrum pubescens</i>, and <i>Trientalis borealis</i>. Mosses include <i>Climacium dendroides, Plagiomnium</i> spp. A floodplain variant may also occur, with more hardwood dominance, with wetter species present, such as <i>Alnus incana, Calamagrostis canadensis</i>, and <i>Caltha palustris</i>. Diagnostic features include the dominance by <i>Fraxinus nigra</i>.
