CEGL006103 Morella pensylvanica - Dasiphora fruticosa / Carex sterilis - Carex flava Fen
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Northern Bayberry - Shrubby-cinquefoil / Dioecious Sedge - Yellow Sedge Fen
Colloquial Name: Northern Piedmont Rich Fen
Hierarchy Level: Association
Type Concept: 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 Dasiphora fruticosa ssp. floribunda and Morella pensylvanica common and Toxicodendron vernix, Acer rubrum, and Juniperus virginiana 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 Carex sterilis, Carex flava, Carex cryptolepis, Carex tetanica, Rhynchospora capillacea, Rhynchospora alba, as well as Parnassia glauca, Sanguisorba canadensis, Drosera rotundifolia, Sarracenia purpurea, Packera aurea, Lobelia kalmii, Panicum flexile, Deschampsia cespitosa, Juncus brachycephalus, Juncus nodosus, Eleocharis tenuis, Muhlenbergia glomerata, Mentha x piperita, and Spiranthes cernua. The invasive exotic shrubs Berberis thunbergii and Rosa multiflora may also be present. The diagnostic characteristic is the presence of Morella pensylvanica in the shrub layer.

Floristics: Although the shrubs are generally sparse (less than 25%), they are characteristic of this vegetation, with Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda) and Morella pensylvanica (= Myrica pensylvanica) common and Toxicodendron vernix, Acer rubrum, and Juniperus virginiana 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 Carex sterilis, Carex flava, Carex cryptolepis, Carex tetanica, Rhynchospora capillacea, Rhynchospora alba, as well as Parnassia glauca, Sanguisorba canadensis, Drosera rotundifolia, Sarracenia purpurea, Packera aurea (= Senecio aureus), Lobelia kalmii, Panicum flexile, Deschampsia cespitosa, Juncus brachycephalus, Juncus nodosus, Eleocharis tenuis, Muhlenbergia glomerata, Mentha x piperita, and Spiranthes cernua. The invasive exotic shrubs Berberis thunbergii and Rosa multiflora may also be present. The diagnostic characteristic is the presence of Morella pensylvanica in the shrub layer.
Dynamics: No Data Available
Environmental Description: This community is a spring-fed calcareous fen generally with minimal peat accumulation over mineral soil or marl. Marl is actively deposited, the result of precipitation of calcium carbonate in supersaturated groundwater seepage upslope. Flowing rivulets are common, and the substrate is typically marl and calcium carbonate-coated stones and woody debris.
Geographic Range: This association is limited to New Jersey and Pennsylvania and possibly southwestern New York.
