CEGL001477 Spartina pectinata - Carex spp. Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Prairie Cordgrass - Sedge species Wet Meadow
Colloquial Name: Prairie Cordgrass - Sedge Wet Meadow
Hierarchy Level: Association
Type Concept: This cordgrass wet prairie type is found in the northwestern Great Plains of the United States. Stands occur in drainage bottoms where the soil is wet for at least part of the growing season, or in poorly drained depressions within floodplains of major rivers. At Wind Cave National Park in South Dakota, this type has dense herbaceous cover, greater than 75%. Species dominance is patchy within stands, with various graminoids locally abundant, often to the exclusion of other species. In the single sampled stand, Spartina pectinata, Carex nebrascensis, and Eleocharis palustris were locally dominant. Epilobium ciliatum was common in shallow water. At Theodore Roosevelt National Park in North Dakota, Spartina pectinata is the dominant species. Species richness is generally low. Hordeum jubatum and Pascopyrum smithii are the most prominent secondary species. Elsewhere Carex pellita may be dominant.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: It is possible that ~Panicum virgatum - (Pascopyrum smithii) Wet Meadow (CEGL001484)$$ could be considered a variant of this type. This type is restricted to the Great Plains ecoregions and is not found in the tallgrass prairie regions of the Midwest, where ~Spartina pectinata - Calamagrostis stricta - Carex spp. Wet Meadow (CEGL002027)$$ is found.

Floristics: At Wind Cave National Park in South Dakota, this type has dense herbaceous cover, greater than 75%. Species dominance is patchy within stands, with various graminoids locally abundant, often to the exclusion of other species. In the single sampled stand, Spartina pectinata, Carex nebrascensis, and Eleocharis palustris were locally dominant. Epilobium ciliatum was common in shallow water (H. Marriott pers. comm. 1999). At Theodore Roosevelt National Park in North Dakota, Spartina pectinata is the dominant species. Species richness is generally low. Hordeum jubatum and Pascopyrum smithii are the most prominent secondary species (J. Butler pers. comm. 1999). At Badlands National Park in South Dakota, prairie cordgrass stands are small, but dense. Aerial cover of the entire herbaceous layer is typically estimated at 75-100%. Spartina pectinata is the dominant species. The stands occupy moist soils and occur adjacent to Eleocharis palustris, Polygonum amphibium, Typha angustifolia, Typha latifolia, and Schoenoplectus pungens (= Scirpus pungens) stands; the latter stands occupy saturated to inundated soils. Adjacent uplands are typically vegetated by Pascopyrum smithii. Elsewhere in the region Carex pellita may be common.
Dynamics: Sites may occasionally flood from rivers or ponding up of depressions.
Environmental Description: At Wind Cave National Park in South Dakota, stands occur in drainage bottoms where the soil is wet for at least part of the growing season (H. Marriott pers. comm. 1999). At Theodore Roosevelt and Badlands national parks, stands occur in poorly drained depressions within floodplains of major rivers.
Geographic Range: This cordgrass wet prairie type is found in the northwestern Great Plains of the United States, particularly in the western Dakotas, Wyoming and eastern Montana.
