Name: Brickellia longifolia Shrubland
Reference: Western Ecology Working Group of...
Description: This brickellbush 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 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 besides north-facing. Soils are rapidly-drained sandy loams and/or sand. Rocks (often cobble-sized), gravel, and sand strongly dominate the ground cover. 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 associate species, although <i>Ephedra fasciculata</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 particular species regularly occur.
