Name: Bouteloua gracilis - Sporobolus cryptandrus Grassland Reference: NatureServe Biotics 2019 Description: This herbaceous association is currently only known from El Malpais National Monument in New Mexico, and the following description is based on occurrences there. Additional information will be added as it becomes available. This association occurs between 2085 and 2200 m (6840-7230 feet) elevation on a variety of landforms including valley bottoms, gentle shoulders or footslopes of low hills, and occasionally kipukas and depositional areas in lavaflows. Substrates are mainly derived from alluvium or sometimes from volcanics or sandstone formations. Typically, ground surface cover is dominated by soil, with gravel, rock, litter, and coarse woody debris as minor components. In some areas, pocket gopher mounds and kangaroo rat burrows have disturbed the soil. In this shortgrass prairie grassland, graminoids dominate (generally &gt;25% cover) with <i>Bouteloua gracilis</i> and <i>Sporobolus cryptandrus</i> the most frequent and abundant species. Forbs are scattered and most frequently include <i>Sphaeralcea coccinea</i> and <i>Artemisia carruthii</i>, along with the non-native <i>Salsola tragus</i>. Among trees, <i>Juniperus monosperma</i> and <i>Pinus edulis</i> are scattered about this grassland association, along with the shrubs <i>Ericameria nauseosa</i> and <i>Gutierrezia sarothrae</i>, but seldom exceed 1 or 2% cover.  Accession Code: urn:lsid:vegbank.org:commConcept:30670-{A4DC4328-637A-45EF-B5F2-3BBE8E2A16BB} Plot-observations of this Community Concept: 0
