Dasiphora fruticosa / Carex interior - Carex flava - Sarracenia purpurea Fen
Translated Name: Shrubby-cinquefoil / Inland Sedge - Yellow Sedge - Purple Pitcherplant Fen
Common Name: Western Allegheny Shrubby-cinquefoil / Sedge Rich Fen
Unique Identifier: CEGL005140
Classification Approach: International Vegetation Classification (IVC)
Summary: This rich fen community is found in the Allegheny region and Lake Erie-Lake Ontario plains of the United States and Canada. Stands occur on level to sloping seepage areas. Sites are minerotrophic and alkaline to circumneutral in character, with groundwater flowing through shallow peats and marls on glacial deposits. Graminoids dominate, though forbs and dwarf-shrubs can be prominent. A tall-shrub layer swamp often surrounds the core fen area. Typical graminoids include the sedges Carex aquatilis, Carex flava, Carex interior, Carex leptalea, Carex lacustris, Carex hystericina, Carex sterilis, and Carex stricta, as well as Cladium mariscoides, Eleocharis rostellata, Eriophorum viridicarinatum. Other herbaceous species include Symphyotrichum puniceum, Doellingeria umbellata, Cypripedium reginae, Muhlenbergia glomerata, Oxypolis rigidior, Platanthera dilatata, Pycnanthemum virginianum, Solidago patula, Solidago uliginosa, Thalictrum dasycarpum, and Thelypteris palustris. Shrubs most characteristic of this type include Dasiphora fruticosa ssp. floribunda and Rhamnus alnifolia, but Aronia melanocarpa, Alnus incana, Cornus amomum, Cornus foemina, Salix candida, Salix sericea, and Viburnum lentago can also be found. A moss layer is commonly well-developed, and may or may not contain species of Sphagnum. The open marl area is often sparsely vegetated, but can contain Chara spp., Juncus brachycephalus, Lobelia kalmii, Parnassia glauca, Rhynchospora capillacea, Sarracenia purpurea, Triglochin maritima, and Triglochin palustris.



Classification

Classification Confidence: Low - Poorly Documented
Classification Comments: This type allows for considerable variability in the shrub component, allowing for as much as 50% shrub cover. Compare with Dasiphora fruticosa / Carex (sterilis, hystericina, flava) Fen (CEGL006326), which may be the same type, but see also Cornus racemosa / Carex (sterilis, aquatilis, lacustris) Fen (CEGL006123). Note that the tall-shrub rich fen equivalent is treated as Cornus sericea - Cornus amomum - Aronia melanocarpa - Viburnum lentago Fen (CEGL005088), but some states, such as Ohio, simply treat these two types as zones within their fen (Schneider and Cochrane 1997). There, the type is restricted to the glaciated Allegheny Plateau in the northeast. In New York it is found in the glaciated Finger Lakes region. In Ontario, the shrubby-cinquefoil type is only reported from Site Region 6, suggesting that the type may not be the same.

NatureServe Conservation Status
Global Status: G3 (24Oct2002)
Rounded Global Status: G3 - Vulnerable
Reasons: This type is found as small patches with somewhat restricted environmental conditions, although it can range from Canada to Ohio. It is found primarily on minerotrophic sites with groundwater flowing through peats and marl on glaciated deposits. In New York, the specific environmental conditions restrict this type to the Central Appalachian and Finger Lake Highlands where it is characterized by cold water fed by small springs or groundwater that is constantly flowing through the community (Reschke 1990). In Ohio, it is primarily found on seepage areas associated with minerotrophic springs atop glacial deposits (Anderson 1996). Few Element Occurrences have been attributed to this type; however, it may be considered a zone within a state type thus making it difficult to document as an independent type.

Environmental Setting

Wetland Indicator: Y
Environmental Summary: Sites are minerotrophic and alkaline to circumneutral in character, with groundwater flowing throughout shallow peats and marls on glacial deposits. In New York, the sloping fens are fed by small springs of groundwater seepage; these are headwater wetlands with cold water constantly flowing through them (Reschke 1990). In Ohio, sites are found in seepage areas of minerotrophic springs associated with gravel deposits in terminal moraines and other glacial forms (Anderson 1996).
