Name: Carex atherodes Seasonally Flooded Herbaceous Alliance
Reference: Midwestern Ecology Working Group...
Description: This alliance, found in the northern Great Plains, typically forms a central core of a wetland or bands along more permanent water. Vegetation cover is usually high but can vary in wet or dry years. Dominant species are herbaceous and typically between 0.5 and 1 m tall. Forb diversity is moderate to high. Carex atherodes can either form almost monotypic stands or be the dominant species. Common associated species include Alisma triviale, Eleocharis palustris, Glyceria grandis (in drier stands), Mentha arvensis, Phalaris arundinacea, Polygonum amphibium, Schoenoplectus fluviatilis (= Scirpus fluviatilis), Scolochloa festucacea (especially on mildly saline sites), Sium suave, and Sparganium eurycarpum. Shrubs, including Salix spp., can invade stands of this alliance, especially in the eastern portions of its range. Stands of this alliance occur on lowland sites that have standing water for several weeks each year. These sites are typically in depressions or basins but can be along streams and rivers. The water may be fresh to mildly saline. Soils can be mineral but mucks often form through the buildup of organic material.
