Name: Encelia resinifera Shrubland Reference: NatureServe Biotics 2019 Description: This sticky brittlebush shrubland association is currently described from Grand Canyon National Park and Grand Canyon-Parashant National Monument in Arizona. More survey and classification work are needed to fully characterize this type. It typically occurs on low and mid sideslopes at 1025 to 1450 m (3375-4750 feet) elevation, but can be found as low as 600 m (1950 feet). It chiefly occurs on moderate to steep gradients (25-40°), but is also found on gentler slopes (10-20°). Soils are well- to rapidly-drained silty or sandy loams or clays, and the underlying geology can vary from limestone to sandstone or shale. Vegetation is characterized and dominated by the short shrub <i>Encelia resinifera</i>. A sparse tall-shrub layer that includes <i>Acacia greggii</i> is infrequently present. The short-shrub layer occasionally supports <i>Ephedra torreyana</i>. A fairly sparse dwarf-shrub layer of <i>Gutierrezia sarothrae</i> and <i>Thamnosma montana</i> occasionally occurs. The exotic <i>Bromus rubens</i> is very common in a relatively well-developed graminoid layer. <i>Muhlenbergia porteri, Achnatherum speciosum</i>, and <i>Aristida purpurea</i> are also somewhat common. A variety of species, including <i>Sphaeralcea grossulariifolia, Gilia</i> sp., <i>Galium stellatum</i>, and <i>Eriogonum inflatum</i>, occur in the forb understory.  Accession Code: urn:lsid:vegbank.org:commConcept:33846-{C0DA8D20-3345-459F-AE7E-275A06B0EDBE} Plot-observations of this Community Concept: 0
