Name: Artemisia longifolia Sparsely Vegetated Alliance
Reference: Western Ecology Working Group of...
Description: This vegetation is known from badlands in the northwestern Great Plains on acid-shale barrens. Elevation in Montana is approximately 1000 m. Stands occur on dry scree slopes, as well as acid-shale barrens. Sites are common on moderate to steep, highly eroded slopes with southern and western aspects. Substrates may be deep, but are poorly developed, fine-textured soils derived from acid marine shales. Because of a large coarse fraction of shale fragments, these soils may be better drained than expected. The sparse vegetation layer is less than 1 m tall and is dominated by the perennial forb Artemisia longifolia with Eriogonum pauciflorum sometimes codominating. Scattered graminoids and other forbs are also typically present and may include Achnatherum hymenoides (= Oryzopsis hymenoides), Calamagrostis montanensis, Calamovilfa longifolia, Schizachyrium scoparium, Solidago missouriensis, Stellaria media, and Thermopsis rhombifolia. Occasional Rosa arkansana shrubs are often present.
