This association is a characteristic back-beach community of ocean beaches of the West Gulf Coast Prairies and Marshes, west of the Mississippi River to Texas and adjacent Mexico. <i>Ipomoea pes-caprae</i> and <i>Ipomoea imperati</i> dominate as sparse to moderately dense trailing vines. Other species that may be present as scattered individuals include <i>Cakile geniculata, Croton punctatus, Erigeron procumbens, Heliotropium curassavicum, Heterotheca subaxillaris, Oenothera drummondii, Physalis viscosa, Sesuvium portulacastrum, Spartina patens, Tidestromia lanuginosa</i>, and <i>Uniola paniculata</i>. |

This low sagebrush association occurs from 1830 to 2750 m (6000-9000 feet) elevation, on slopes from 10-42%, often on northern aspects, in concave snowpockets in northern Nevada, and generally on southern exposures in eastern Idaho. Soils are deep Mollisols (average 117 cm), of fine loam texture with gravel fragment up to 30%. This low-stature shrubland is dominated by a combination of <i>Artemisia tridentata ssp. vaseyana</i> and <i>Symphoricarpos oreophilus</i>, sometimes one more dominant than the other, but both always present with at least 10% cover. Other shrubs that may be present include <i>Chrysothamnus viscidiflorus, Ribes</i> spp., and <i>Purshia tridentata</i>. The understory is sparsely to occasionally thickly dominated by grasses. <i>Pseudoroegneria spicata</i> is always present and usually the most abundant grass with 2-10% cover. Other grasses commonly present include <i>Festuca idahoensis, Poa fendleriana, Achnatherum nelsonii ssp. dorei (= Stipa columbiana), Achnatherum lettermanii (= Stipa lettermanii), Bromus tectorum</i>, and <i>Melica bulbosa</i>. Common forbs include <i>Lupinus caudatus, Achillea millefolium, Balsamorhiza sagittata, Collinsia parviflora</i>, and <i>Helianthella uniflora</i>. |

This sagebrush shrubland is known only from Grand Teton National Park but is expected to occur in the surrounding area in southeastern Idaho and elsewhere in Wyoming. One stand occurs on the valley floor, with a 4% slope at an elevation of 2060 m (6749 feet), on a dry southeastern aspect. The soil is a loam with gravel and cobble. The shrub layer is dominated by <i>Artemisia tridentata ssp. vaseyana</i> and <i>Symphoricarpos oreophilus</i>. Graminoids include <i>Hesperostipa comata</i> and <i>Poa pratensis</i>. The most abundant forb is <i>Balsamorhiza sagittata</i>. Other forbs present include <i>Eriogonum umbellatum, Lupinus sericeus, Geranium viscosissimum, Lithospermum ruderale</i>, and <i>Helianthella uniflora</i>. Similar vegetation types have been described in the literature with an <i>Artemisia tridentata</i> canopy and an undergrowth of <i>Hesperostipa comata (= Stipa comata)</i>. However, these do not refer to <i>Artemisia tridentata ssp. vaseyana</i>, nor do they mention any <i>Symphoricarpos</i> spp. as present. |

This subalpine conifer forest association occurs in the southern Rocky Mountains extending to high mountains and plateaus of central and southwestern New Mexico, southeastern and eastern Arizona and southeastern Utah at elevations between 2713 and 3500 m (8900-11,460 feet). This type is characterized by deep snowpack and brief, cool summers. Stands are common in the middle to upper subalpine zones in the southern extent on all aspects and slopes, but are more common in upper montane and lower subalpine zones in the northern portion of its range. Sites are relatively mesic and are typically on mid to lower slopes with cooler northerly or easterly aspects, e.g., less xeric and cold than forests with understories dominated by <i>Vaccinium scoparium</i> or <i>Ribes</i> spp., but less mesic stands with <i>Carex rossii</i>- or <i>Carex geyeri</i>-dominated understories. Soils are typically shallow (sometimes deeper than 60 cm), rocky and loamy. Litter and duff cover a significant portion of the ground surface (25-40%). Bedrock, large rock, and small rock combined cover 15-50%. Moss and lichen cover is 3-35%. The vegetation has a moderately dense to dense tree canopy codominated by <i>Picea engelmannii</i> and <i>Abies lasiocarpa</i>, with an understory characterized by a dwarf-shrub layer dominated by <i>Vaccinium myrtillus</i>. <i>Populus tremuloides</i> and <i>Pinus contorta</i> (northern stands only) are the most common seral species, though <i>Pseudotsuga menziesii</i> occurs at lower elevations. In the understory, <i>Vaccinium scoparium</i> may be present but is usually trace to less than half the cover of <i>Vaccinium myrtillus</i>. Other shrubs may be present at low cover such as <i>Acer glabrum, Linnaea borealis, Lonicera involucrata, Mahonia repens, Paxistima myrsinites</i>, and <i>Ribes montigenum</i>. Herbaceous species such as <i>Arnica cordifolia, Bromus ciliatus (= Bromopsis ciliata),Carex rossii, Erigeron eximius</i> (warm, moist sites), <i>Geranium richardsonii, Lathyrus</i> spp., <i>Orthilia secunda, Osmorhiza berteroi (= Osmorhiza chilensis), Pedicularis racemosa, Orthilia secunda (= Pyrola secunda)</i>, and <i>Thalictrum fendleri</i> are species which are commonly present with low cover values. |
