This regional endemic grassland association occurs in the Wallowa Mountains, Hells Canyon, Seven Devil Mountains, and Salmon River Mountains of eastern Oregon, Washington and Idaho. The association occurs on gentle to steep southeast-, north-, to southwest-facing, lower, mid, and upper slopes and ridgetops at 460-1830 m (1500-6000 feet) elevation in highly dissected foothills and canyon slope terrain. The grassland vegetation is codominated by <i>Festuca idahoensis</i> and <i>Pseudoroegneria spicata</i>. These species form a relatively dense bunchgrass canopy. <i>Poa secunda</i> is consistently present in the understory. Important herbaceous species include <i>Sedum stenopetalum, Eriophyllum lanatum, Arnica sororia, Castilleja</i> spp., <i>Allium acuminatum, Calochortus</i> spp., <i>Achillea millefolium, Balsamorhiza sagittata, Crepis acuminata</i>, and <i>Lupinus</i> spp. |

This association is known from sites in the lower Snake River basin and northern Wallowa Mountains. Stands also appear to occur in the upper Hells Canyon region within Idaho. The association is transitional to ridgetop habitats that do not support <i>Pseudoroegneria spicata</i> (<i>Poa secunda - Danthonia unispicata</i> sites) and those that support <i>Festuca idahoensis</i> (e.g., <i>Festuca idahoensis - Koeleria macrantha</i> sites). The association occurs on gentle to moderately steep, south- to southwest-facing convex ridgetops at 1120 to 1585 m (4000-5200 feet) elevation. Shallow soils are derived from basalt bedrock. <i>Pseudoroegneria spicata</i> dominates these scabland bunchgrass stands. <i>Poa secunda</i> is codominant. Principal indicator forbs include <i>Lomatium cous, Erigeron chrysopsidis, Balsamorhiza incana, Sedum lanceolatum</i>, and <i>Sedum stenopetalum</i>. |

This grassland association occurs in the Columbia Basin and Great Basin across north-central Wyoming east to the Big Horn Mountains into the northwestern Great Plains. Stands occur on a variety of sites that include windswept slopes and ridges. Sites range from gentle to steep slopes on all aspects. Bare soil, leaf litter, and gravel cover most of the ground surface. The vegetation is characterized by an open to moderately dense bunchgrass layer codominated by <i>Pseudoroegneria spicata</i> and <i>Hesperostipa comata</i>. The dwarf-shrubs <i>Artemisia frigida</i> and <i>Gutierrezia sarothrae</i> occur with sparse cover. Other graminoids include <i>Bouteloua gracilis, Carex</i> spp., <i>Koeleria macrantha, Leymus cinereus, Poa fendleriana</i>, and <i>Poa secunda</i>. Associated forbs include <i>Astragalus</i> spp., <i>Comandra umbellata, Phlox hoodii</i>, and <i>Sphaeralcea munroana</i>. The exotic annual grass <i>Bromus </i><i>tectorum</i> is present to abundant on some sites. |

This herbaceous association is currently only known from El Malpais National Monument in New Mexico and Great Sand Dunes National Park and Preserve in Colorado, and the following description is based on occurrences there. Additional information will be added as it becomes available. At El Malpais, this association occurs between 1950 and 1960 m (6410-6430 feet) in elevation in swales and broad, shallow drainages in gently rolling, old lava plateaus. A prairie dog colony is present at one location, with the attendant soil disturbance and vegetation cropping. At Great Sand Dunes, it generally occurs on valley floors but can be found on sandsheets and bolsons. Elevations range from 2300 to 2335 m. Terrain is flat and stands can be intermittently flooded. Soils are somewhat to moderately drained silt, sandy loam, or loamy sand and derived from alluvial deposits. Bare soil is the dominant ground surface cover ranging from 0-88%. Many of the surveyed stands have experienced heavy grazing by bison, cattle and elk. Total herbaceous vegetation ranges from 35-85% and is dominated by graminoid species. <i>Sporobolus airoides</i> is abundant to luxuriant (up to 40% relative cover) and typically the dominant species in these monotypic grasslands. Species richness is moderately high, but few species have significant cover or are found consistently across all surveyed stands. <i>Juncus balticus</i> and <i>Cleome serrulata</i> are the only two other species that occur in the majority of the stands at Great Sand Dunes, but have low cover. At El Malpais, other species are present, but not abundant; they include <i>Tamarix ramosissima</i> and <i>Opuntia imbricata (= Cylindropuntia imbricata)</i>, among others. |

This association is characteristic of rocky slopes in the Colorado Plateau and extends into the southern Rocky Mountains in western Colorado and northeastern Arizona. Elevations and aspects are variable. Stands occurring at lower elevations (1406-2006 m) on the Colorado Plateau and northwestern Colorado tend to occur on northerly aspects, whereas stands occurring in west-central and southwestern Colorado occur at higher elevations (2481-2510 m) and have southerly aspects. Stands throughout the range may be on gentle to steep slopes (7-160%). Soils are rapidly drained, but texture and parent materials vary from clay to sandy loam and from marine shale to sandstone and granite. The unvegetated ground surface is composed primarily of exposed bedrock, rocks, gravel and bare ground. This woodland association has an open to relatively closed tree canopy and sparse to dense total vegetation cover. <i>Juniperus osteosperma</i> and <i>Pinus edulis</i> comprise the tree canopy, but individually do not exceed 25% cover. There is a tall-shrub stratum with up to 25% cover dominated by <i>Amelanchier utahensis</i>. Other shrubs that may be present with low cover include <i>Artemisia tridentata, Cercocarpus montanus, Fraxinus anomala, Ephedra viridis, Fendlera rupicola, Quercus gambelii, Rhus trilobata</i>, and <i>Symphoricarpos oreophilus</i>. Dwarf-shrubs may include <i>Yucca harrimaniae, Gutierrezia sarothrae</i>, and <i>Chrysothamnus viscidiflorus</i>. The herbaceous layer has sparse to low cover and contains graminoids, such as <i>Achnatherum hymenoides, Carex geyeri, Leymus salinus</i>, and <i>Poa fendleriana</i>, and forbs, such as <i>Antennaria parvifolia, Erigeron peregrinus, Eriogonum ovalifolium, Heterotheca villosa, Lathyrus lanszwertii, Lepidium montanum, Phlox austromontana</i>, and <i>Streptanthella longirostris</i>. Disturbed stands may contain <i>Bromus tectorum</i>. |

Sporobolus flexuosus - Paspalum setaceum Herbaceous Vegetation

This is a desert grassland association, known from one occurrence, in southwestern New Mexico. The association occurs in a desert valley between isolated desert mountain ranges. Most of the annual precipitation of about 35 cm occurs during the summer months as the result of convectional thunderstorms and during winter as occasional rains. Late spring and early summer are typically dry. Summers are hot, and winters can have periods of cold weather and occasional snows. This association is found on the edge of a sandy playa bottom, where there is a slight slope. The elevation of the single occurrence is 1580 m (5180 feet). <i>Sporobolus flexuosus</i> generally occurs in loose and/or blowing sands. The edge of the playa is probably inundated less often than the center of the playa, consequently salinity on the edge could be high. There is no shrub layer; the herbaceous layer averages 20-40% cover and is dominated by the perennial bunchgrass <i>Sporobolus flexuosus</i>. Several other species common to sandy substrates are present, the best indicator being the bunchgrass <i>Paspalum setaceum</i>. Forbs are moderately sparse, averaging less than 15% total cover, and in the Gray Ranch occurrence the perennial forb <i>Chamaesyce albomarginata (= Euphorbia albomarginata)</i> is the most abundant with 10% cover. Other species include <i>Bouteloua parryi</i> and <i>Aristida divaricata</i>. This plant association is presently known from extreme southwestern New Mexico on the Gray Ranch, Hidalgo County. Other possible locations include Texas, but the association has not been documented from there. |

This community occurs in isolated small depressions in Piedmont upland settings, holding water much or all of the growing season and wet enough that trees are excluded from the interior or at least sparsely scattered there. The vegetation is an open mix of shrubs and herbs, with <i>Cephalanthus occidentalis</i> or <i>Leucothoe racemosa</i> generally dominating. <i>Carex joorii</i> is most typically the dominant herb, but other wetland graminoids may occur. The flora is depauperate and does not include large numbers of plants with Coastal Plain affinities. <i>Quercus phellos</i> generally occurs along the edge, and <i>Liquidambar styraciflua</i> or <i>Acer rubrum</i> may also be present. |
