Name: Muhlenbergia montana - Schizachyrium scoparium Grassland Reference: NatureServe Biotics 2019 Description: This association is only known to occur at Bandelier National Monument in north-central New Mexico. The current description is based on data received from there and will be updated when additional inventory data are available. This mid-elevation association occurs on sites with moderate solar exposure (mostly northerly aspects). Stands generally occur on gently rolling mesatops (4-10%) and occasionally on moderately steep mesa toeslopes (25%). Soils are primarily mapped as well-developed Mollisols derived from rhyolitic tuff or pumice slope alluvium, or occasionally as fine-textured Alfisols derived from eolian deposits over rhyolitic tuff residuum. The ground surface is typically characterized by bunchgrasses with inter-grass spaces covered with leaf litter or some exposed soil. Elevation ranges between 2200 and 2360 m (7220-7740 feet). This montane grassland association is characterized by abundant to luxuriant growth of <i>Muhlenbergia montana</i> with <i>Schizachyrium scoparium</i> as a codominant. <i>Bouteloua gracilis</i> and <i>Andropogon gerardii</i> are also common associates. Total grass cover can approach 50%. Forbs are typically well-represented in these grasslands and most frequently include <i>Artemisia carruthii</i> and <i>Heterotheca villosa</i>. Among trees, scattered <i>Pinus ponderosa</i> saplings and mature trees can occur, but cover is less than 10%. Shrubs are also poorly represented, but <i>Quercus gambelii</i> and <i>Robinia neomexicana</i> may be common.  Accession Code: urn:lsid:vegbank.org:commConcept:34141-{F325C212-9E23-4086-8714-75D252CDE81B} Plot-observations of this Community Concept: 0
