CEGL000742 Juniperus scopulorum / Artemisia nova Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Rocky Mountain Juniper / Black Sagebrush Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This Juniperus scopulorum-dominated open woodland has been described from dry rocky ridges and upper slopes in the Pryor Mountains in Montana. Elevation ranges from 1830-1980 m. Sites have shallow, rocky soils derived from calcareous parent materials. Ground surface usually exceeds 50% cover of gravel and rock (combined) with bare soil exceeding 5%. Stands typically have a relatively sparse tree canopy (10% cover) of Juniperus scopulorum with scattered Pseudotsuga menziesii. The sparse short-shrub layer (15% canopy cover) is dominated by Artemisia nova with scattered Petrophytum caespitosum, Gutierrezia sarothrae, and Ribes cereum. The sparse herbaceous layer (<25% cover) is dominated by the graminoids Poa secunda, Pseudoroegneria spicata, and Koeleria macrantha. Forb cover is generally very sparse (<10%) but may be relatively diverse and includes species such as Allium sp., Antennaria microphylla, Eriogonum ovalifolium, Phlox hoodii, Packera cana, and the cactus Opuntia polyacantha. Adjacent vegetation includes ~Pseudotsuga menziesii / Symphoricarpos oreophilus Forest (CEGL000462)$$ in relatively moist drainages. In the Great Basin, there are two common woodland types, ~Juniperus osteosperma / Artemisia nova Woodland (CEGL000728)$$ and ~Juniperus osteosperma / Artemisia nova / Rock Woodland (CEGL000729)$$, that are similar except for being dominated by a different species of Juniperus.
