CEGL005998 Artemisia cana / Juncus arcticus ssp. littoralis Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Silver Sagebrush / Baltic Rush Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This silver sagebrush shrubland is only known from Fossil Butte National Monument in southwestern Wyoming. Stands occur in low-lying riparian and wetland sites. It occupies first terraces of principle drainages, in tributary channels, or mesic swales that seasonally flood or are saturated. Sites are generally flat to gently sloping and between 2039 and 2388 m elevation, with stands occurring in swales found on steeper slopes (to 14°). The unvegetated surface has low to moderate exposure of bare soil, high cover of litter, and sparse cover of downed wood. Soils are somewhat poorly to moderately well-drained and texturally are silty clay, clay loam, or clay derived from the Angelo Member of the Wasatch Formation, and sandstones and shale that have eroded and deposited as either new alluvium or secondary stream alluvium. The vegetation is characterized by a moderate to dense short-shrub layer dominated by Artemisia cana and sparse to moderately dense cover of Juncus arcticus ssp. littoralis. Total vegetation cover ranges from 49-99%. The short shrub Rosa woodsii is typically present with sparse cover. The herbaceous layer is dominated by graminoids and has low species diversity, with Carex praegracilis providing low to moderate cover, while the grasses Deschampsia cespitosa, Leymus cinereus, Poa glauca, and Poa secunda provide low cover. Forbs present with sparse to low cover include Achillea millefolium, Argentina anserina, Astragalus agrestis, Descurainia pinnata, Glyceria striata, Senecio integerrimus, Solidago gigantea, and Solidago velutina. Disturbed stands may be codominated by Poa pratensis, along with other common introduced species, such as Ceratocephala testiculata, Iva axillaris, and Taraxacum officinale.

Floristics: The vegetation is characterized by a moderate to dense short-shrub layer dominated by Artemisia cana (15-68% cover) and sparse to moderately dense cover of Juncus arcticus ssp. littoralis (= Juncus balticus) (4-45% cover). Total vegetation cover ranges from 49-99%. The short shrub Rosa woodsii is typically present with sparse cover. The herbaceous layer is dominated by graminoids and has low species diversity, with Carex praegracilis providing low to moderate cover, while the grasses Deschampsia cespitosa, Leymus cinereus, Poa glauca, and Poa secunda provide low cover. Forbs present with sparse to low cover include Achillea millefolium, Argentina anserina (= Potentilla anserina), Astragalus agrestis, Descurainia pinnata, Glyceria striata, Senecio integerrimus, Solidago gigantea, and Solidago velutina (= Solidago sparsiflora). Disturbed stands may be codominated by Poa pratensis, along with other common introduced species, such as Ceratocephala testiculata, Iva axillaris, and Taraxacum officinale.

Environmental Description: This silver sagebrush shrubland is only known from Fossil Butte National Monument in southwestern Wyoming. Stands occur in low-lying riparian and wetland sites. It occupies first terraces of principle drainages, in tributary channels, or mesic swales that seasonally flood or are saturated. Sites are generally flat to gently sloping (<5%) and between 2039 and 2388 m elevation, with stands occurring in swales found on steeper slopes (to 14°). The unvegetated surface has low to moderate exposure of bare soil, high cover of litter, and sparse cover of downed wood. Soils are somewhat poorly to moderately well-drained and texturally are silty clay, clay loam, or clay derived from the Angelo Member of the Wasatch Formation, and sandstones and shale that have eroded and deposited as either new alluvium or secondary stream alluvium.
Geographic Range: This silver sagebrush shrubland is only known from Fossil Butte National Monument in southwestern Wyoming and likely is more widespread in southern Wyoming.
