Name: Pseudoroegneria spicata Sparsely Vegetated Alliance
Reference: Western Ecology Working Group of...
Description: This alliance is known only from eroded slopes in the Pryor Mountains of southern Montana, at elevations ranging from 1280-1525 m. Stands are commonly found on moderate to steep, highly eroded slopes with southern and western aspects. Soils are deep, alkaline with sandy clay to clay texture. They are derived from shale, bentonite, claystone or sandstone interbedded with clay. The soil surface has high cover of gravel and cobbles. Cryptogamic soil crusts may form on gentler, less disturbed slopes. These communities are characterized by a sparse herbaceous layer that is codominated by Pseudoroegneria spicata and Eriogonum brevicaule. Other characteristic forbs and grasses include Arenaria hookeri, Machaeranthera grindelioides, Achnatherum hymenoides (= Oryzopsis hymenoides), Poa secunda, and species of Astragalus and Cryptantha. Eriogonum pauciflorum is occasional. Scattered shrubby species, such as Ericameria nauseosa (= Chrysothamnus nauseosus), Gutierrezia sarothrae, Atriplex confertifolia, Artemisia tridentata, and an occasional Juniperus osteosperma tree, may also be present.
