Name:
Calamagrostis canadensis - Carex spp. Laurentian & Northeast Wet Meadow
Reference:
NatureServe Biotics 2019
Description:
This wet meadow vegetation is widespread in the Laurentian-Acadian and northeast regions of Canada and the United States. Stands occur on the floodplains of small streams, in poorly drained depressions, beaver meadows, levees and lakeshores. Soils are typically mineral soil or well-decomposed peat, with a thick root mat. Water regime varies between temporarily and seasonally flooded. Graminoid cover is typically dense and can form hummocky microtopography. <i>Calamagrostis canadensis</i> is dominant, often occurring in almost pure stands or with tall sedges, such as <i>Carex aquatilis, Carex lacustris, Carex utriculata</i>, and <i>Carex stricta</i>. In fen transitions, <i>Carex lasiocarpa</i> can be present. <i>Agrostis gigantea, Glyceria grandis, Poa palustris, Poa compressa, Scirpus cyperinus</i>, and <i>Typha latifolia</i> are sometimes abundant. Forbs include <i>Campanula aparinoides, Epilobium leptophyllum, Eutrochium maculatum, Eupatorium perfoliatum, Impatiens capensis, Iris versicolor, Polygonum amphibium</i>, and <i>Comarum palustre</i>. Scattered shrubs, such as <i>Viburnum nudum, Viburnum dentatum, Spiraea alba, Cornus amomum, Alnus incana</i>, or <i>Alnus serrulata</i>, may be present. <i>Phalaris arundinacea</i> and/or <i>Lythrum salicaria</i> may be present, especially in disturbed examples.
