CEGL002698 Artemisia nova / Poa fendleriana Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Black Sagebrush / Muttongrass Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This short-shrub association occurs locally in southern Utah and western Colorado on the slopes and tops of ridges and plateaus, as well as the sides of drainages. Stands are usually small to medium-sized patches in a mosaic of other types of shrubland. Elevations range from 1830 to 3000 m (6000-9840 feet). Stands occur on gentle to moderately steep slopes with a tendency toward north and east aspects. Soils and substrates are variable but generally are rocky and shallow. The vegetation is characterized by a shrub layer dominated by Artemisia nova with between 5 and 25% cover; associated species such as Amelanchier utahensis, Artemisia tridentata, Tetradymia canescens, Symphoricarpos oreophilus, and Purshia tridentata contribute another 10-25%. The herbaceous layer is diverse, but Poa fendleriana is among the dominants with between 5 and 20% cover. Other common grasses include Koeleria macrantha, Bouteloua gracilis, Elymus elymoides, and Poa secunda. Forbs contribute relative little cover and are inconsistent among sites.

Floristics: This short-shrub association occurs in small patches, usually surrounded by other types of shrublands. Total vegetation cover ranges from 10 to 60%. The shrub layer is dominated by Artemisia nova with between 5 and 25% cover; associated species such as Amelanchier utahensis, Artemisia tridentata, Tetradymia canescens, Symphoricarpos oreophilus, and Purshia tridentata contribute another 10-25%. The herbaceous layer is diverse, but Poa fendleriana is among the dominants with between 5 and 20% cover. Other common grasses include Koeleria macrantha, Bouteloua gracilis, Elymus elymoides, and Poa secunda. Forbs contribute relative little cover and are inconsistent among sites.
Dynamics: Fire removes Artemisia nova from this community, converting it to a sparse mixed grassland.
Environmental Description: This short-shrub association occurs locally in southern Utah and western Colorado on the slopes and tops of ridges, mesas and plateaus, as well as the sides of drainages. Elevations range from 1830 to 3000 m (6000-9840 feet). Stands occur on gentle to moderately steep slopes (3-35%) with a tendency toward north and east aspects. Soils and substrates are variable but generally are rocky and shallow, with bare ground, gravel and rock providing a high percentage of the unvegetated ground cover. There is a slight tendency for Artemisia nova shrublands to occur on calcareous substrates such as limestone, marlstone and some types of volcanic rock.
Geographic Range: This association has been documented from Zion and Capitol Reef national parks in southern Utah and from Curecanti National Recreation Area in western Colorado.
