Name: Pseudoroegneria spicata - Eriogonum brevicaule Sparse Vegetation
Reference: Western Ecology Working Group of...
Description: This sparse vegetation association occurs within the Bighorn Basin of south-central Montana. The habitat consists of very arid, steep, highly eroded and eroding slopes with southern or western aspects. These 'badland' environments form a band on the slopes of the Pryor Mountains from 1280-1525 m elevation. This community likely occurs in similar 'badlands' habitats in adjacent areas in Wyoming. Soils are deep, alkaline sandy clay or clay 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. The total vegetation cover is typically less that 25% and is typically codominated by the cool-season, medium-tall bunchgrass <i>Pseudoroegneria spicata</i> (7% mean cover) and the warm-season, perennial forb <i>Eriogonum brevicaule</i> (8% mean cover). Other species may include scattered shrubs, such as <i>Ericameria nauseosa (= Chrysothamnus nauseosus), Gutierrezia sarothrae, Atriplex confertifolia</i>, the grasses <i>Achnatherum hymenoides (= Oryzopsis hymenoides)</i> and <i>Poa secunda</i>, and the forbs <i>Arenaria hookeri, Cryptantha</i> spp. and <i>Machaeranthera grindelioides</i>. Stands are characterized by a sparse herbaceous layer that is codominated by <i>Pseudoroegneria spicata</i> and <i>Eriogonum brevicaule</i>.
