CEGL005270 Eriogonum pauciflorum - Gutierrezia sarothrae Badlands Sparse Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Few-flower Buckwheat - Broom Snakeweed Badlands Sparse Vegetation
Colloquial Name: Wild Buckwheat - Snakeweed Badlands
Hierarchy Level: Association
Type Concept: 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 Eriogonum pauciflorum, Gutierrezia sarothrae, Opuntia polyacantha, Atriplex argentea, Cryptantha thyrsiflora, and the forb Grindelia squarrosa. Atriplex canescens dwarf-shrubs may be observed throughout the type but are typically short-statured and scattered in distribution.

Floristics: This badlands community type rarely exceeds 10% vegetative cover and is 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 Eriogonum pauciflorum, Gutierrezia sarothrae, Opuntia polyacantha, Atriplex argentea, and Cryptantha thyrsiflora, and the forb Grindelia squarrosa. Atriplex canescens dwarf-shrubs were observed throughout the type but were typically short-statured and scattered in distribution (Von Loh et al. 1999).

Environmental Description: In Badlands National Park, South Dakota, this type is typically found on silty/sandy outwash fans newly deposited by eroding badlands formations. These formations include Cretaceous Pierre shale, Oligocene Brule siltstone, Chadron clayey mudstone and shale, and Miocene Arickaree sandstone. Soils are undeveloped, poor, loose, and easily eroded. The topography is typically flat, and stands occur on erosional outwash fans. One stand, composed of four-wing saltbush, occupies a large badlands flat and erosion fan (Von Loh et al. 1999).
Geographic Range: This badlands type is found in the northwestern Great Plains in badlands topography.
