Name: Redbeds (Siltstone, Sandstone, Gypsum) Sparse Vegetation
Reference: NatureServe Biotics 2019
Description: The Redbeds rock outcrop type is found in the Black Hills region of the United States. Stands occur on outcrops of the Permo-Triassic Spearfish Formation, composed of red siltstones and shales. Gypsum lenses are common and often cap the slopes, small hills and buttes where redbeds are exposed. Due to the softness of the parent rock material, exposures are often eroded to produce badlands-like topography. Occasionally, small cliff-like outcrops develop where strata are more resistant to erosion. This is a sparse vegetation type with total vegetative cover usually less than 10%. Graminoids and forbs typically are equally represented. Frequently found species include <i>Artemisia frigida, Hesperostipa comata, Schizachyrium scoparium, Achnatherum hymenoides, Tetraneuris acaulis, Oxytropis lambertii, Heterotheca villosa, Paronychia depressa, Eriogonum pauciflorum, Hymenopappus filifolius</i>, and many other prairie forbs. Lichens and cryptogamic soils may be present.
