CEGL001523 Artemisia arbuscula ssp. longiloba / Poa secunda Shrub Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Alkali Sagebrush / Sandberg Bluegrass Shrub Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This short shrub-steppe association is found between 1450 and 2600 m (4750-8530 feet) elevation in northern Nevada, southwestern Idaho, southwestern Wyoming and north-central Colorado. It is located on gentle to moderate slopes or rolling uplands, ridges, alluvial fans, and basin bottoms on most aspects. Soils tend to be a heavy clay loam. Artemisia arbuscula ssp. longiloba dominates the shrub overstory. Traces to low cover of Purshia tridentata, Chrysothamnus viscidiflorus, and Ericameria nauseosa may also be present. Elymus elymoides and Festuca idahoensis are consistently present along with Poa secunda. Common forbs include Allium acuminatum, Eriogonum caespitosum, and Phlox hoodii.

Floristics: This association has an open to moderately dense short-shrub layer dominated by Artemisia arbuscula ssp. longiloba with sparse to moderate cover of Poa secunda consistently present in the herbaceous layer. Other shrubs often present with low cover include Artemisia tridentata, Chrysothamnus viscidiflorus, Ericameria nauseosa, Purshia tridentata, Symphoricarpos spp., and Tetradymia canescens. Grass associates include Elymus elymoides and Poa fendleriana along with Poa secunda. Pseudoroegneria spicata is usually absent or has low cover. Other associated graminoids include Achnatherum hymenoides, Achnatherum lettermanii, Elymus lanceolatus, Festuca idahoensis, and Poa glauca. Forbs provide sparse to low cover and include Agoseris glauca, Allium acuminatum, Arenaria kingii, Antennaria dimorpha, Collinsia parviflora, Eriogonum caespitosum, Eriogonum umbellatum, Lomatium spp., Mertensia oblongifolia, Phlox hoodii, Phlox longifolia, Phlox multiflora, Pteryxia terebinthina (= Cymopterus terebinthinus), Stenotus acaulis, and Trifolium gymnocarpon. Exotics such as Alyssum desertorum, Bromus tectorum, Ceratocephala testiculata (= Ranunculus testiculatus), Iva axillaris, and Taraxacum officinale are common on disturbed sites.

Environmental Description: This short shrub-steppe association is found between 1450 and 2600 m (4750-8530 feet) elevation in northern Nevada, southwestern Idaho, southwestern Wyoming and north-central Colorado. Stands occur on gentle to moderate slopes or rolling uplands, ridges, alluvial fans, and basin bottoms on most aspects. The unvegetated surface has moderate to high exposure of bare soil, low to moderate cover of small rocks, and low to moderate cover of litter. Soils tend to be heavy clay loams and clays derived from alluvium and the Troublesome Formation (Colorado) or Wasatch Formation (Wyoming) but also include well-drained to rapidly drained loamy sand.
Geographic Range: This low-shrub association is found on the Owyhee Plateau in southwestern Idaho, north-central Colorado (Middle Park), and northeastern Nevada (Elko County). It is also believed to be present to fairly common in the southwestern quarter of Wyoming.
