This montane shrubland association has been described from mountains of western Colorado and plateaus of southwestern Utah. Elevation ranges from 2000-2737 m (6560-8977 feet). Sites include nearly level mesas, talus slopes, hillslopes, benches, gullies and streambeds to steep mountain slopes (to 34°). North and northwest aspects are most frequent, but stands are reported from all aspects. Sites are often relatively mesic, occurring at the base of cliff bands and talus slopes, on concave slopes, near rivers and along drainages. Soils are often deep, well-drained clay loam derived from sandstone; however, substrates are variable and are derived from a variety of parent materials. The vegetation is characterized by an open to dense tall-shrub layer (2-5 m tall) that is dominated by <i>Quercus gambelii</i> with a open to moderately dense short-shrub layer dominated by <i>Prunus virginiana</i>,. Scattered trees ( especially <i>Pseudotsuga menziesii</i>) may be present with low cover. If <i>Amelanchier alnifolia</i> or <i>Amelanchier utahensis</i> are present, they are subdominant in the short-shrub layer, although they may have up to 25% cover. Other shrubs present with low cover (typically <5%) include <i>Acer glabrum, Artemisia tridentata, Chrysothamnus viscidiflorus, Cornus sericea, Mahonia repens, Paxistima myrsinites, Philadelphus microphyllus, Rhus trilobata, Ribes cereum, Ribes inerme, Rosa woodsii, Salix geyeriana, Salix scouleriana</i>, and <i>Symphoricarpos oreophilus</i>. <i>Holodiscus dumosus</i> is common on many of the talus sites, often forming its own community about the oak-choke cherry shrubland. <i>Salix exigua</i> is abundant in one streambed plot. The herbaceous layer varies from absent to moderate (0-30% cover). Common herbaceous species include graminoids, such as <i>Carex geyeri, Deschampsia caespitosa, Elymus elymoides, Hesperostipa comata</i>, and <i>Poa fendleriana</i>, and forbs, including <i>Artemisia ludoviciana, Galium boreale, Maianthemum stellatum, Solidago canadensis, Thalictrum fendleri, Vicia americana</i>, and <i>Wyethia amplexicaulis</i>. |

This association is described from sites located in the White Knob and Pioneer mountains of central Idaho (Challis Volcanics ecoregional section). The association occurs in alpine fell-field environments. The gently sloped ridgecrest sites occur at approximately 10,400-11,000 feet elevation. The association consists of a very low-growing, prostrate mat of herbaceous species and few graminoids. Ivesia gordonii is dominant and associated with Minuartia obtusiloba (= Arenaria obtusiloba), Phlox pulvinata, Smelowskia calycina, Selaginella densa, and Oxytropis parryi. |

This oak-palmetto bottomland forest is found in limited areas in the West Gulf Coastal Plain. Possibly the most characteristic feature of the community is the dense, almost continuous understory cover of Sabal minor. The canopy is dominated by Quercus phellos and Quercus nigra, typically with an admixture of species such as Quercus michauxii, Ulmus americana, and Pinus taeda. The subcanopy is dominated by Carpinus caroliniana ssp. caroliniana. In addition to the dense layer of Sabal minor, the shrub stratum includes Sebastiania fruticosa, Ilex vomitoria, Arundinaria gigantea, Crataegus marshallii, Ilex decidua, Toxicodendron radicans, Parthenocissus quinquefolia, small stems of Quercus phellos, and Campsis radicans. The herbaceous stratum tends to be sparse below the dense layer of Sabal minor, but may include Chasmanthium laxum, Carex louisianica, Justicia ovata, and Sphagnum spp. |

This maritime forest occurs on Grand Isle, Jefferson Parish, Louisiana. It is dominated by Quercus virginiana, with a minor component of Celtis laevigata var. laevigata. It is apparently unlike other chenier forests in southwestern Louisiana (L. Smith pers. comm.) and other maritime Quercus virginiana forests east of Louisiana. All known occurrences are degraded. |
