Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Greasewood Dune Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This greasewood dune shrubland occurs in the mountains of Colorado and Columbia Plateau and Great Basin of Nevada and possibly Utah. 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 found in dunefields, sandsheets, and stabilized dunes at 2300 to 2390 m elevation. Stands are generally on flat terrain, but slopes can be up to 17°. The majority of stands are characterized by large patches of bare soil with shrubs interspersed. Sand and bare soil dominate the ground cover, although some stands have significant cover of litter. Vegetative cover is extremely variable for this association. Sarcobatus vermiculatus is always present, typically in combination with other short shrubs such as Atriplex canescens, Chrysothamnus greenei, Ericameria nauseosa, and Krascheninnikovia lanata. Herbaceous cover is sparse. Species present in some stands include Bassia americana, Achnatherum hymenoides, Artemisia frigida, Chenopodium leptophyllum, and Opuntia polyacantha.

Floristics: Vegetative cover is extremely variable for this association. Total cover can range from 1-85%. Sarcobatus vermiculatus is always present (20-80%), typically in combination with other short shrubs such as Atriplex canescens, Chrysothamnus greenei, Ericameria nauseosa, and Krascheninnikovia lanata with cover ranging from 0-10%. Herbaceous cover is sparse, generally 20% or less. Species present in some stands with up to 5-10% cover include Bassia americana (= Kochia americana), Achnatherum hymenoides, Artemisia frigida, Chenopodium leptophyllum, and Opuntia polyacantha.
