click to update datacart
Name: Artemisia tridentata / Bouteloua gracilis Shrubland Reference: NatureServe Biotics 2019 Description: This shrubland has only been described from the plateaus and mesas of Grand Canyon and Zion national parks in northwestern Arizona and southwestern Utah, but it is more widespread and likely occurs in New Mexico and Nevada. Sites range from valley bottoms and drainages to rolling hills, mesa tops and terraces. Substrates are alluvial soils derived from limestone or volcanic flows or sandy-textured soil derived from sandstone or sandy limestone. Stands have an open, short-shrub canopy (less than 1 m tall) that is dominated by the evergreen microphyllous shrub <i>Artemisia tridentata</i> usually with greater than 20% cover. Other common shrubs and dwarf-shrubs may include <i>Gutierrezia sarothrae, Chrysothamnus viscidiflorus, Atriplex canescens, Krascheninnikovia lanata</i>, or <i>Ephedra viridis</i>. The sparse herbaceous layer is dominated by the short perennial bunchgrass <i>Bouteloua gracilis</i> with <i>Achnatherum hymenoides, Pascopyrum smithii</i>, or <i>Sporobolus cryptandrus</i> often present. Forbs are sparse. Scattered <i>Juniperus osteosperma</i> trees and succulents such as <i>Opuntia</i> spp. may also be present.  Accession Code: urn:lsid:vegbank.org:commConcept:29904-{93FA00F7-4BAC-4136-BC2A-7208B476084A} Plot-observations of this Community Concept: 1
