Name: Eriogonum leptophyllum Sparse Vegetation Reference: NatureServe Biotics 2019 Description: This sparsely vegetated badland association occurs at Petrified Forest National Park in northern Arizona and likely occurs elsewhere in the southern Colorado Plateau. Elevations at the national park range from 1710 to 1770 m (5620-5810 feet). Stands are found on gentle to moderately steep slopes and range between 4 and 65%. This association occurs on various landforms, including lower slopes, sideslopes, midslopes, bajadas, slick rock, buttes, cliffs, and plateaus. Substrates are clays derived from shale. The ground surface has high cover of bare soil. A few stands have surface rocks with substrates including petrified wood, sandstone, and mudstone. The vegetation cover is characterized by generally sparse (&lt;10%) total vegetation cover that ranges from 7-23% cover that is composed of scattered low shrubs (5-17% cover) dominated by <i>Eriogonum leptophyllum</i>. Other shrubs present with low cover may include <i>Atriplex confertifolia, Atriplex obovata, Ephedra torreyana, Eriogonum subreniforme, Gutierrezia sarothrae</i>, and <i>Yucca angustissima</i>. A sparse herbaceous cover may be present with scattered <i>Eriogonum divaricatum, Parryella filifolia, Pleuraphis jamesii</i>, and <i>Sporobolus airoides</i>. Exotic species are present on some stands, such as <i>Bromus tectorum</i> and <i>Sisymbrium altissimum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:32861-{7B0F7A73-4EE7-45EB-B621-A180B520D53B} Plot-observations of this Community Concept: 0
