Name:
Morella pensylvanica - Dasiphora fruticosa ssp. floribunda / Carex sterilis - Carex flava Shrub Herbaceous Vegetation
Reference:

Description:
This calcareous fen association is characterized by herbaceous vegetation maintained by groundwater springs. It is restricted to New Jersey, Pennsylvania, and perhaps New York. Peat accumulation is minimal, with mineral soil or marl often evident at the surface, particularly where groundwater emerges. Although the shrubs are generally sparse (less than 25%), they are characteristic of this vegetation, with <i>Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda)</i> and <i>Morella pensylvanica (= Myrica pensylvanica)</i> common and <i>Toxicodendron vernix, Acer rubrum</i>, and <i>Juniperus virginiana</i> as frequent associates. Wettest portions of these fens lack woody vegetation. The herbaceous cover is usually about 40%. It is rich and diverse and includes the sedges <i>Carex sterilis, Carex flava, Carex cryptolepis, Carex tetanica, Rhynchospora capillacea, Rhynchospora alba</i>, as well as <i>Parnassia glauca, Sanguisorba canadensis, Drosera rotundifolia, Sarracenia purpurea, Packera aurea (= Senecio aureus), Lobelia kalmii, Panicum flexile, Deschampsia caespitosa, Juncus brachycephalus, Juncus nodosus, Eleocharis tenuis, Muhlenbergia glomerata, Mentha x piperita</i>, and <i>Spiranthes cernua</i>. The invasive exotic shrubs <i>Berberis thunbergii</i> and <i>Rosa multiflora</i> may also be present. The diagnostic characteristic is the presence of <i>Morella pensylvanica</i> in the shrub layer.
