Name: Erodium cicutarium Ruderal Annual Grassland Reference: NatureServe Biotics 2019 Description: This small-patch annual exotic herbaceous association occurs on ridges and valley bottoms in highly disturbed sites in the Colorado Plateau. Sites occupied by this association are generally associated with severe disturbance, such as annual grazing by sheep and/or cattle, mining or a very hot fire. Elevations range from 1692 to 2306 m (5550-7565 feet), and sites occur on level to moderate slopes with south to west exposures. Soils are generally sandy and derived from eolian or alluvial deposits. Cryptobiotic crusts may cover much of the unvegetated surface in sites that have not been grazed recently. Total vegetation cover is sparse to moderate (16-40%), depending on the amount of winter/spring precipitation and the time of year a site is sampled. The exotic annual forb <i>Erodium cicutarium</i> provides most of the vegetative cover, but other weedy and exotic species are also generally present, including <i>Bromus tectorum, Descurainia pinnata, Sisymbrium altissimum, Carduus nutans</i>, and <i>Tragopogon dubius</i>. A few scattered shrubs typical of sandy alkaline conditions may be present, including <i>Atriplex canescens, Opuntia polyacantha, Ephedra viridis, Lycium pallidum</i>, and <i>Quercus gambelii</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:30994-{EB8A0EC9-C235-4AA5-BFDB-0B5DAA9750FC} Plot-observations of this Community Concept: 0
