Name: Festuca (calligera, arizonica, brachyphylla) Grassland Reference: NatureServe Biotics 2019 Description: This grassland association is currently described from Grand Canyon National Park in Arizona. More survey and classification work are needed to fully characterize this type. It occurs in high-elevation meadows typically in flat, low-level valley bottoms, or in wide open drainage bottoms, at 2550 to 2750 m (8350-9050 feet). Soils are silt loams and vary from dry to moist. This association is a purely herbaceous vegetation type and lacks tree and shrub cover. <i>Festuca</i> sp. (<i>Festuca calligera, Festuca arizonica, Festuca brachyphylla</i>) is the dominant component of the graminoid layer. <i>Muhlenbergia montana</i> consistently occurs and is more abundant on drier sites, while <i>Deschampsia cespitosa</i> can occur on more mesic sites. The presence of <i>Blepharoneuron tricholepis</i> is characteristic of this association as well. Forb species typically account for 15-20% total cover, and almost 50 different species may be present. <i>Potentilla hippiana, Achillea millefolium, Pseudocymopterus montanus</i>, and <i>Hymenoxys subintegra</i> are the most common forbs, while <i>Ranunculus cardiophyllus, Arenaria fendleri, Eriogonum racemosum, Antennaria rosulata</i>, and <i>Solidago nana</i> are also fairly common. Graminoids are typically dominant in this plant association; however, the forb component can be very well-developed and codominant on some sites. This plant community supports a uniquely southwestern floristic assemblage, but also hosts many higher-elevation or higher-latitude species from the Rocky Mountain region.  Accession Code: urn:lsid:vegbank.org:commConcept:34259-{0711FE33-8A81-4235-95E9-6241E5836590} Plot-observations of this Community Concept: 0
