Name: Ceanothus fendleri / Poa fendleriana Shrub-Steppe Reference: NatureServe Biotics 2019 Description: This Fendler's buckbrush shrubland 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 areas that have experienced somewhat recent high-intensity fires, and typically occurs within a matrix of live <i>Pinus ponderosa</i> woodlands. It occurs from 2440 to 2575 m (8000-8422 feet) elevation on the high-level plateau or upper sideslopes, typically on south- or southeast-facing aspects. Slopes are usually gentle (1-7°) but can occasionally be much steeper (up to 27°). Soils are characterized by silty or sandy loams. Tree cover is essentially absent in this association, as sites have experienced stand-replacing fire events; however, scattered <i>Pinus ponderosa</i> occasionally persist. <i>Ceanothus fendleri</i> dominates the shrub component and can occur as either a short shrub or dwarf-shrub. No other shrub species are consistently present or comprise significant cover. <i>Poa fendleriana</i> dominates the herbaceous layer, while <i>Bromus tectorum</i> and <i>Elymus elymoides</i> also occur frequently. A variety of forbs occur at low cover, including the fire-loving <i>Erigeron divergens, Gayophytum diffusum, Chenopodium</i> sp., <i>Conyza canadensis</i>, and <i>Epilobium brachycarpum</i>. <i>Heterotheca villosa</i> and <i>Solidago velutina</i> occur fairly consistently and with substantial cover values.  Accession Code: urn:lsid:vegbank.org:commConcept:34260-{090A117C-5C65-4841-9323-B5031A45D32C} Plot-observations of this Community Concept: 0
