CEGL001555 Artemisia cana ssp. cana / Calamovilfa longifolia Shrub Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Plains Silver Sagebrush / Prairie Sandreed Shrub Wet Meadow
Colloquial Name: Silver Sagebrush / Prairie Sandreed Shrub Prairie
Hierarchy Level: Association
Type Concept: This upland vegetation type has been described from the Cheyenne River Basin in northeastern Wyoming and has been reported from the Powder River Basin in north-central Wyoming and from the Ferris Mountains and Seminoe Mountains areas in central Wyoming. In all of these areas, it occupies stabilized sand dunes. Artemisia cana ssp. cana forms an open shrub layer to about 50 cm tall, which often contains Artemisia tridentata and Ericameria spp. as well. Common herbaceous species are Calamovilfa longifolia, Hesperostipa comata, Cryptantha spp., and Eriogonum spp., and other plants (especially Bouteloua gracilis, Pascopyrum smithii, and Andropogon hallii) may be conspicuous and contribute substantial cover. Bromus tectorum and other exotics may be common.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Information on the composition and structure of this association seems to be limited. A summary table with quantitative (though incomplete) information has been published for 6 stands in the Cheyenne River Basin. Only species lists or anecdotal information are available for the other areas in Wyoming where the association is thought to occur on the sands range site. Consequently the association is only poorly known. Its relationship to ~Artemisia cana ssp. cana / Hesperostipa comata Shrub Wet Meadow (CEGL001553)$$ is particularly unclear. The two would seem to differ in the relative amounts of Calamovilfa longifolia and Hesperostipa comata present, but both species occur in both of the associations, and the diagnostic differences between the two associations is unclear.

Floristics: Artemisia cana ssp. cana forms an open shrub layer to about 50 cm tall, which often contains Artemisia tridentata and Ericameria spp. (= Chrysothamnus spp.) as well. Common herbaceous species are Calamovilfa longifolia, Hesperostipa comata, Cryptantha spp., and Eriogonum spp., and other plants (especially Bouteloua gracilis, Pascopyrum smithii, and Andropogon hallii) may be conspicuous and contribute substantial cover. Bromus tectorum and other exotics may be common.

Environmental Description: It occupies stabilized sand dunes.
Geographic Range: This upland vegetation type has been described from the Cheyenne River Basin in northeastern Wyoming and has been reported from the Powder River Basin in north-central Wyoming and from the Ferris Mountains and Seminoe Mountains areas in central Wyoming. Artemisia cana ssp. cana and Calamovilfa longifolia both are widespread in the Great Plains, so this association may well extend beyond the areas of Wyoming where it is now thought to occur.
