Description:
This tall-shrub rich fen community type is found in northeastern Ohio and western Pennsylvania, particularly in the Allegheny region and probably elsewhere in the eastern Great Lakes area of the northeastern United States. Stands are found on moraines, especially where gravels permit calcareous seepage, and occur both in lake basins and stream valleys. Soils are organic, with strongly to weakly minerotrophic woody, saturated peat. Shrubs dominant the stands, with over 50% cover, including both tall (>1 m) and short shrubs (<1 m). Tall shrubs include <i>Alnus incana, Aronia melanocarpa, Betula pumila, Cornus amomum, Cornus sericea, Salix candida, Salix serissima</i>, and <i>Viburnum lentago</i>. Low shrubs include <i>Lonicera oblongifolia, Dasiphora fruticosa ssp. floribunda, Rhamnus alnifolia</i>, and <i>Toxicodendron vernix</i>. More nutrient-poor stands may contain <i>Chamaedaphne calyculata, Gaylussacia baccata, Ilex verticillata</i> and <i>Vaccinium corymbosum</i>. Trees, such as <i>Acer rubrum</i> or <i>Larix laricina</i>, may be present as saplings or stunted trees. Characteristic herbs include the graminoids <i>Carex aquatilis, Carex lacustris, Carex lasiocarpa</i>, and <i>Schoenoplectus acutus</i>, and forbs and ferns, such as <i>Iris versicolor, Osmunda regalis, Sarracenia purpurea</i>, and <i>Thelypteris palustris</i>. Characteristic mosses include <i>Campylium stellatum</i> and <i>Sphagnum warnstorfii</i>, though <i>Sphagnum</i> cover varies from absent to patchy.
