This grassland association is known to occur in the mountains of northern New Mexico. It most commonly occurs on gently rolling mesatops, terraces, and occasionally along canyon footslopes (4-10% slopes) on sites with moderate solar exposure. Elevation ranges from 1670 to 2230 m (5470-7310 feet). Soils are primarily fine-textured Alfisols derived from eolian or slope alluvium deposits over rhyolitic tuff residuum, or occasionally well-developed Mollisols derived from pumice slope alluvium. The ground surface is characterized by bunchgrass patches in a matrix of exposed soil and litter with little or no gravel or rock. The vegetation within this association is characterized by abundant to luxuriant grass cover dominated by <i>Bouteloua gracilis</i> (30-60%). Other common grasses may include <i>Elymus elymoides, Pleuraphis jamesii</i>, and <i>Sporobolus cryptandrus</i>. While forbs are typically poorly represented, the ruderal subshrub <i>Gutierrezia sarothrae</i> can be dominant and reach up to 30% cover. Ruderal succulents such as <i>Opuntia phaeacantha</i> or <i>Opuntia polyacantha</i> may also be common. Trees are absent or represented by scattered individuals of <i>Juniperus monosperma</i> or <i>Pinus edulis</i>, mostly as seedlings or saplings. |

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. |

This pinyon-juniper woodland association is currently described from Grand Canyon-Parashant National Monument in Arizona. More survey and classification work are needed to fully characterize this type. It typically occurs at 1875 to 1925 m (6150-6300 feet) elevation on gently sloping (1-7°) high-level plateaus and sideslopes, and occurs across all aspects. Soils are moderately- to well-drained silty clays derived from basalt parent material. This association typically supports an open tree canopy consisting of <i>Juniperus osteosperma</i> and <i>Pinus monophylla</i>. In half of the stands, there is a notable subcanopy comprised also of <i>Pinus monophylla</i> and <i>Juniperus osteosperma</i>. Beneath the tree canopy is an extremely sparse short-shrub layer of <i>Ceanothus greggii</i> and <i>Artemisia tridentata</i>. Dwarf-shrubs such as <i>Gutierrezia sarothrae</i> and <i>Opuntia</i> sp. often occur at trace covers. <i>Bouteloua gracilis</i> dominates a well-developed graminoid component, while <i>Poa fendleriana, Elymus elymoides</i>, and <i>Aristida purpurea</i> are frequent at lower covers. Common forbs include <i>Penstemon linarioides, Eriogonum umbellatum</i>, and <i>Hymenoxys richardsonii</i>. |
