Tsuga canadensis - (Betula alleghaniensis) Forest
Reference:
NatureServe Biotics 2019
Description:
This mesic hemlock evergreen forest is found in the Great Lakes region of the United States and Canada. Stands occur on deep, acidic soils that may be poorly drained. The overstory of this community is strongly dominated by <i>Tsuga canadensis</i>, typically around 25 m tall. <i>Betula alleghaniensis</i> is often present in the canopy and subcanopy, but at less than 25% cover. Other species that are a minor component of the canopy include <i>Abies balsamea, Acer rubrum, Acer saccharum, Pinus strobus, Tilia americana</i>, and <i>Thuja occidentalis</i>. The sapling layer may also contain <i>Abies balsamea</i> and <i>Thuja occidentalis</i>, especially in canopy gaps. Shrubs are rare and herbaceous species only moderately abundant under the dense evergreen canopy; however, where gaps occur, <i>Acer pensylvanicum, Acer spicatum, Amelanchier</i> spp., <i>Gaultheria procumbens, Lonicera canadensis</i>, and <i>Rubus idaeus</i> may be moderately abundant. The herbaceous layer is poor under drier, more evergreen stands, and richer under more moist and somewhat deciduous stands. Herbaceous species found in this community include <i>Aralia nudicaulis, Clintonia borealis, Coptis trifolia, Cornus canadensis, Dryopteris carthusiana, Huperzia lucidula, Maianthemum canadense, Oxalis montana, Pteridium aquilinum, Streptopus lanceolatus var. longipes</i>, and <i>Trientalis borealis</i>. A sparse to dense moss layer includes <i>Brachythecium reflexum, Callicladium haldanianum, Dicranum flagellare, Dicranum montanum, Mnium marginatum, Plagiothecium laetum, Polytrichum commune, Ptilidium pulcherrimum</i>, and <i>Tetraphis pellucida</i>.
