CEGL000728 Juniperus osteosperma / Artemisia nova Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Utah Juniper / Black Sagebrush Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs on the slopes of ridges, saddles and benches below 2200 m elevation in the Colorado Plateau and Great Basin. Substrates and soils are variable but tend to be coarse and contain a calcareous element. Juniperus osteosperma forms an open canopy, with a sparse to moderate understory of Artemisia nova. The herbaceous layer tends to be sparse and dominated by graminoids, including Poa secunda.

Floristics: This woodland association is characterized by an open canopy (10-40% cover) of Juniperus osteosperma. Pinus edulis is occasionally present with less than 1% cover. Artemisia nova dominates the sparse to moderate shrub layer (2-25% cover); other shrubs that may contribute to the shrub layer include Ephedra viridis, Gutierrezia sarothrae, Amelanchier utahensis, and Purshia tridentata. The herbaceous layer is variable and generally sparse, with few species exceeding 1% cover. The most common herbaceous species include Poa secunda, Leymus salinus, Pleuraphis jamesii, and Phlox spp.
Dynamics: Calcareous substrates and shallow soils discourage competition by shrubs such as Artemisia tridentata. While most stands are woodlands with a shrub understory, occurrences in Nevada are arranged as a tight mosaic, with Artemisia nova on ridgelines and Juniperus osteosperma in swales (Blackburn et al. 1968c).
Environmental Description: This association occurs in small to moderate patches (<1 to approximately 10 ha) on saddles, benches and ridges within the Colorado Plateau and Great Basin. Stands occur on gentle to moderate slopes oriented to any aspect between 1500 and 2200 m (4920-7220 feet) elevation. The substrate is often a calcareous shale, sandstone, or volcanic tuff. Soils are generally shallow sandy loams with a high percentage of bare ground or desert pavement accounting for most of the non-vegetated surface.
Geographic Range: This association is known to occur in Idaho, western Colorado, northeastern Utah, and northern and central Nevada. It is suspected to occur in eastern California but has not yet been documented from there.
