CEGL002416 Carex interior - Carex lurida - Andropogon gerardii - Parnassia grandifolia Seepage Fen
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Inland Sedge - Shallow Sedge - Big Bluestem - Largeleaf Grass-of-Parnassus Seepage Fen
Colloquial Name: Ozark Prairie Fen
Hierarchy Level: Association
Type Concept: This prairie fen community type is found in the Ozarks region of the United States. Stands occur on the valley terraces of larger streams and rivers. Soils are moist to wet, and seasonally saturated by calcareous internal groundwater seepage. Soils are muck or mucky peat, alkaline (pH above 6.5), and shallow (40-100 cm), or, locally, very shallow with gravel at the surface. The parent material is a gravelly alluvium or colluvium over dolomite bedrock. The bedrock strata are detectable. Fires are possible in some of the larger fens. A mix of tallgrass and herbaceous calciphiles dominate the vegetation. Scattered shrubs may occur. Dominant graminoids include Andropogon gerardii, Sorghastrum nutans, and Spartina pectinata. Other characteristic graminoids include Carex interior, Carex lurida and Panicum virgatum. Characteristic forbs include Castilleja coccinea, Helianthus grosseserratus, Helianthus mollis, Lysimachia quadriflora, Lythrum alatum, Oxypolis rigidior, Pycnanthemum tenuifolium, Pycnanthemum virginianum, Rudbeckia fulgida var. umbrosa, Silphium integrifolium, Silphium terebinthinaceum, and Veronicastrum virginicum. More rarely, Platanthera leucophaea may occur.
