Name: Eriogonum pauciflorum - Gutierrezia sarothrae Badlands Sparse Vegetation Reference: Midwestern Ecology Working Group... Description: This badlands type is found in the northwestern Great Plains, in badlands topography. In Badlands National Park, South Dakota, stands occur on eroded formations of Cretaceous Pierre shale, Oligocene Brule siltstone and Chadron clayey mudstone and shale, and Miocene Arickaree sandstone. Brule formation siltstone is often capped by Rocky Ford volcanic ash and may also contain veins of chalcedony. Soils are undeveloped, poor, loose, and easily eroded. The topography is typically flat, and stands occur on erosional outwash fans. Structurally, stands rarely exceed 10% vegetative cover (often less than 5%). On level terrain, the vegetation is relatively evenly distributed, but on steeper slopes and cliffs the vegetation may grow in patches and in rows or seams. In Badlands National Park, plant species that are nearly always present include the dwarf-shrubs <i>Eriogonum pauciflorum, Gutierrezia sarothrae, Opuntia polyacantha, Atriplex argentea, Cryptantha thyrsiflora</i>, and the forb <i>Grindelia squarrosa</i>. <i>Atriplex canescens</i> dwarf-shrubs may be observed throughout the type but are typically short-statured and scattered in distribution.  Accession Code: VB.CC.36965.CEGL005270 Plot-observations of this Community Concept: 0
