Name: Brickellia longifolia Shrubland Reference: NatureServe Biotics 2019 Description: This association is currently known from the Colorado Plateau in Grand Canyon National Park in northern Arizona and Glen Canyon National Recreation Area in southern Utah. This sparse association is characterized and dominated by the short shrub <i>Brickellia longifolia</i>. Trees are lacking, but the exotic <i>Tamarix ramosissima</i> occurs in the tall-shrub stratum somewhat frequently. The short-shrub layer is almost devoid of associated species, although <i>Ephedra aspera</i> and <i>Acacia greggii</i> rarely occur. The dwarf-shrub layer is also essentially lacking, but <i>Gutierrezia sarothrae</i> does occur in the majority of stands. Annuals, particularly non-native annuals, constitute the majority of the sparse graminoid layer. <i>Bromus rubens, Bromus tectorum</i>, and <i>Vulpia octoflora</i> frequently occur. The forb understory is particularly variable in this association; no one species regularly occurs. This association occurs in cobble-filled, rocky drainage bottoms, most commonly in low-level, low-gradient (1-3°) drainages which experience intermittent flooding events. It chiefly occurs at 700 to 1250 m (2350-4100 feet) elevation, and across all aspects except north-facing. Soils are rapidly drained sandy loams and/or sand. Rocks (often cobble-sized), gravel, and sand often dominate the ground cover.  Accession Code: urn:lsid:vegbank.org:commConcept:34152-{C69A67AF-212C-4DC0-B7AD-539687E76235} Plot-observations of this Community Concept: 0
