CEGL005087 Cornus amomum - Salix spp. - Toxicodendron vernix - Rhamnus lanceolata Fen
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Silky Dogwood - Willow species - Poison-sumac - Lanceleaf Buckthorn Fen
Colloquial Name: Dogwood - Willow - Poison-sumac Shrub Fen
Hierarchy Level: Association
Type Concept: This tall-shrub fen community type is found in the central midwestern 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 calcareous seepage causing saturated conditions. The vegetation is dominated by tall shrubs 1-3 m in height, with a mixture of herbaceous species in the ground layer. Tall shrubs include Cornus amomum, Cornus sericea, Toxicodendron vernix, Rhamnus lanceolata, Salix discolor, Salix sericea, and Viburnum lentago. Vaccinium corymbosum may also be present. Herbaceous species include Cypripedium reginae, Filipendula rubra, Solidago patula, and Woodwardia virginica. The prairie species component in this tall-shrub fen is a diagnostic characteristic.

Classification Comments: This type is found in western Ohio prairie shrub fens, as well as northern Indiana and Illinois tall-shrub circumneutral fens. It is the tall-shrub counterpart to the low-shrub/herb prairie fen, ~Dasiphora fruticosa / Carex sterilis - Andropogon gerardii - Arnoglossum plantagineum Fen (CEGL005139)$$. This type is very similar to the more circumneutral shrub fen/bog, ~Cornus spp. - Salix spp. - Vaccinium corymbosum - Rhamnus alnifolia - Toxicodendron vernix Fen (CEGL005083)$$ and the two types could probably be combined. It is also similar to ~Cornus sericea - Salix spp. - (Rosa palustris) Shrub Swamp (CEGL002186)$$, but that type is a shrub swamp rather than fen. However, these tall shrub swamps are difficult to distinguish in terms of fen versus swamp. This type is found in southern Wisconsin and southern Michigan. However, although the type is fairly distinctive, it is often a relatively small zone on the edge of low shrub/graminoid fens, and is not always recognized or tracked.
