This herbaceous alpine vegetation type has been described from Carter Mountain along the eastern side of the Absaroka Mountains in northwestern Wyoming. The sites on which stands of this association grow are the middle parts of steep, lee (easterly) slopes where snow accumulates early and remains until mid-summer. Soils on these sites are deep. The vegetation is dense and two-layered, with Lupinus argenteus forming a tall (40 cm) herbaceous layer above a shorter herbaceous layer of Poa spp., Geum rossii, the cushion forb Arenaria congesta, and other species. The species of Poa found in this type are unidentified in the literature. |

Picea pungens / Poa pratensis Woodland

This association is found in the Pecos and Rio Grande basins of north-central New Mexico. Preliminary data suggest that it occurs on high, flat terraces of narrow montane streams. Terrace formation is usually between low riverbars and higher, drier, upland hillslopes. Soils of this type are loamy and silty over a gravelly-cobbly matrix. Soils have high plant-available water, and they can have wetness (hydric) indicators, but these are deep in the soil profile. On sites near the active stream channels, soils can be relatively moist (coarse-silty Oxyaquic Ustifluvents); others are drier and more developed (Fluventic Dystrochrepts), particularly on older terraces. Most sites are estimated to flood infrequently (75- to 100-year flood-recurrence interval). The type is known to occur at upper elevations ranging between 2350 and 2775 m (7725-9100 feet). It is characterized by an open canopy of <i>Picea pungens</i> with a grassy understory dominated by <i>Poa pratensis</i>, with only scattered, if any, shrubs. Overall species diversity is moderately high with 67 species recorded for the type, of which 14 are introduced exotics, and 12 are native wetland indicators. |

This type is known only from interdune swales of gypsum dunelands of the Tularosa Basin in south-central New Mexico at elevations around 1220 m (4000 feet) and may also occur in the Trans-Pecos region of Texas. In the interdune areas, water accumulates during the summer rainy season, and the water table remains near the surface (0.5 m). Mature <i>Populus deltoides</i> trees form very open canopies (30% or less cover) with a grassy understory dominated by the gypsophile <i>Schizachyrium scoparium var. scoparium (= Schizachyrium neomexicanum)</i> along with <i>Sporobolus airoides</i> as a common associate. Scattered <i>Baccharis salicina</i> and <i>Tamarix ramosissima</i> are often present in the shrub layer. Although overall diversity is relatively low (29 species), there are six wetland indicators and only one exotic. |
