Hierarchy Level:  Association

Type Concept: This wetland herbaceous association is found in the Rocky Mountains and Great Plains of Colorado and Oklahoma. This description is based on information from Great Sand Dunes National Park and Preserve in Colorado. Additional global information will be added as it becomes available. This association is located in swales and floodplains of basins surrounded by sand dunes at 2335 m elevation. Surveyed sites are most often semipermanently to temporarily flooded. Soils are poorly drained sandy loams or very poorly drained muck. Ground cover is dominated by either litter and duff (68%) or bare soil (75%). The surveyed areas experience heavy use by bison, elk, and deer. Herbaceous vegetation is dominated by Schoenoplectus americanus with 20-40% cover. Iris missouriensis can be a codominant, but does not occur in every surveyed stand. Additionally, Carex praegracilis can occur at high cover levels, but does not have a consistent dominant presence. Other commonly occurring species that can have variable percent covers, ranging from 10-20%, include Carex utriculata, Argentina anserina, and Hordeum jubatum.
