In this nonriverine swamp forest, <i>Liquidambar styraciflua, Nyssa biflora</i>, and <i>Acer rubrum var. trilobum</i> are the constant and dominant species, with lesser amounts (and lower constancy) of <i>Ulmus rubra, Ulmus americana, Fraxinus pennsylvanica, Nyssa aquatica, Populus heterophylla, Quercus laurifolia, Quercus pagoda, Quercus shumardii, Quercus lyrata, Taxodium distichum</i>, and <i>Taxodium ascendens</i>. Subcanopy species can include <i>Ilex opaca, Fraxinus caroliniana</i>, and <i>Magnolia virginiana</i>. <i>Clethra alnifolia</i> is the characteristic shrub species, and often grows densely. Typical herbs (none with high cover) are <i>Carex gigantea, Carex louisianica, Lobelia inflata</i>, and <i>Saururus cernuus</i>. This association occurs at Roquist Pocosin, near the mouth of the Roanoke River, and in other wet nonriverine flats. the species composition suggests a higher nutrient status than some other nonriverine swamp associations. |

This is a very broadly distributed association occurring in the major ranges of northern Utah, Wyoming, Idaho, eastern Washington and Montana into at least west-central Alberta. In drier climates it is a small-patch type, but with higher precipitation regimes; it can expand to large patches in valley locations. Elevations range from 1250 m in the north to 3355 m at the highest in the south. In the southern portion of this type's distribution, parent materials are largely alluvium, soils are loamy to silty in texture, derived from the local country rock, which ranges from sandstone to basalt to granitics in the vicinity of major batholiths. In the north, sedimentary and metasediments are the rule with silty clay loams and loams predominating. Mottling and rust pockets are found in many soil pits, indicating high water tables or subirrigation for a portion of the year. Subirrigation is reflected by landscape positions on lower terraces and stringers of lower order streams, toeslopes and side-hill seeps. Most of the indicator forbs present are associated with the decidedly rich end of the soil-nutrient regime. The canopy for the most part is open, the modal cover ranging between 40-60%, dominated by <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i>. <i>Pinus contorta</i> is the major seral species in the middle Rockies, whereas in the northern Rockies <i>Pseudotsuga menziesii, Larix occidentalis, Pinus monticola</i>, and <i>Abies grandis</i> are additional seral species. The dominant aspect of the undergrowth is an abundance of medium to tall forbs, though shrub cover can at times approach 50%; shrubs are a more important component in the northern distribution of the association. Shrubs with the highest constancy and cover include <i>Ribes lacustre, Vaccinium membranaceum, Alnus viridis ssp. sinuata, Lonicera utahensis, Cornus sericea</i>, and <i>Menziesia ferruginea</i>. The graminoid component is negligible. Of the forbs diagnostic for the association four, <i>Streptopus amplexifolius, Senecio triangularis, Heracleum maximum</i> and <i>Mitella pentandra</i>, are distributed across the breadth of the type, though there are numerous ancillary high-constancy forbs spanning the type's range including <i>Thalictrum occidentale, Geranium richardsonii, Osmorhiza berteroi, Maianthemum stellatum, Orthilia secunda</i>, and <i>Arnica cordifolia</i> (or <i>Arnica latifolia</i> at higher elevations). <i>Aconitum columbianum, Saxifraga odontoloma, Mertensia ciliata</i>, and <i>Mertensia arizonica</i> are wet-site taxa occurring with relatively high constancy in the southerly portion of the association. The forb component of diagnostic species is more diverse from central Idaho northward. |

This is a sparsely vegetated shrubland found on seasonally wet, alkaline playas, intermittent floodplains or along washes in saline overflow areas below 1680 m (5500 feet) elevation. The dominant species, and playa communities in general, are widely distributed throughout the Intermountain West, ranging from southeastern Oregon south to Texas. These shrublands or barrens are flat to extremely low-gradient, almost always in desert ecosystems with less than 18 cm (7 inches) of rain per year, and usually in areas with very poor drainage that flood during rare rainstorms. Playas and washes dominated by <i>Allenrolfea occidentalis</i> generally appear to be small, rare, and poorly understood throughout their range. <i>Allenrolfea occidentalis</i> dominates the shrub layer, but cover is often quite low, ranging from 20% to less than 1%. Most stands have barren playa forb understories, but grasses, including <i>Leymus cinereus, Distichlis spicata, Sporobolus airoides</i>, and <i>Sporobolus wrightii</i>, and succulent forbs, such as <i>Suaeda suffrutescens var. detonsa, Salicornia</i> spp., and <i>Nitrophila</i> spp., are occasionally found. Most stands occur in a matrix of <i>Sarcobatus vermiculatus</i>- or <i>Atriplex canescens</i>-dominated shrublands, and in small stands, either <i>Sarcobatus vermiculatus</i> or <i>Atriplex canescens</i> can occur throughout the community. |

This seasonally flooded shrubland association occurs in the upper subalpine-lower alpine zones in the southern Rocky Mountains at elevations from 2600-3500 m (8500-11,760 feet). Stands occur along the drier periphery of broad, glaciated basins and along first- and second-order streams in the subalpine zone. Stream channels are wide and shallow, or narrow, deep and sinuous. Sites are gentle to steep, well-drained mesic slopes and elevated hummocks above wetter areas and drainages vegetated with <i>Salix planifolia</i> associations. Substrates are silty clay loams to sandy loams with some mottling. Many stands grow among rocky substrates and have high cover of exposed bedrock and large and small rock on the ground surface. The vegetation is characterized by a moderate to dense low-shrub canopy strongly dominated by <i>Salix brachycarpa</i>, with an understory dominated by mesic forbs. <i>Salix planifolia</i>-dominated associations occur within the same riparian/wetland mosaic in lower, poorly drained areas and intermix with the <i>Salix brachycarpa</i> association at their ecotone. Within this association <i>Salix planifolia</i> has less than 30% cover. Other shrubs may include <i>Salix wolfii</i> (present to codominant), <i>Betula glandulosa</i> (in high, subalpine/alpine stands), <i>Salix monticola</i> (present to codominant), and <i>Salix drummondiana</i> (in more montane stands). Alpine dwarf-shrubs and scattered krummholz <i>Picea engelmannii</i> may also be present. The herbaceous layer is dominated by a diversity of mesic forbs, which exceeds total graminoid cover, and no single forb species is dominant or present in every stand. Associated forb species include <i>Caltha leptosepala, Cardamine cordifolia, Fragaria virginiana, Hymenoxys hoopesii, Mertensia ciliata, Senecio triangularis</i>, and <i>Thalictrum alpinum</i>. Graminoid species may include <i>Calamagrostis canadensis, Carex aquatilis, Carex microptera, Carex utriculata</i>, and <i>Deschampsia cespitosa</i>. Alpine stands have higher frequency of more characteristic tundra species. Lichen- and moss-covered boulders are often present. |

This association occurs on the Western Slope and Front Range of the southern Rocky Mountains and is documented from over 20 locations in Colorado at an elevational range of 2300-3150 m (7700-10,320 feet). Stands occur on broad alluvial floodplains with steep sideslopes. This riparian shrubland has a tall, mixed, deciduous shrub canopy that is codominated by <i>Salix geyeriana</i> and <i>Salix monticola</i> with an understory altered by livestock grazing. The herbaceous layer consists of dense grasses and forbs on a hummocky ground surface. Season-long grazing has increased the non-native grass component of this association. Stands with their native herbaceous undergrowth intact are extremely rare. |

This wet grassland association occurs widely throughout mountainous areas of the western United States and Canada. These grasslands are a relatively small, meadow association that occurs in broad glaciated valleys, openings in moist forests, silted-in beaver ponds, and narrow floodplains of lower montane canyons. Elevations range from 670 to 3415 m (2200-11,200 feet). Parent material is generally coarse alluvium or fine glacial tills. Soils are Inceptisols, Entisols, and occasionally Mollisols. Textures range from clay loam, silty clay and silt loam to sand. Occurrences may have an organic layer on the surface as well as significant amounts of sand and rock in the lower layers, and are poorly to moderately well-drained. Stands generally stay relatively wet to moist throughout the growing season, are often flooded in the spring, and the water table drops 50-80 cm from the surface by late summer. This association is typically a dense sward of graminoid cover dominated by <i>Calamagrostis canadensis</i>. Other graminoid species usually present include <i>Carex aquatilis</i> and <i>Glyceria</i> spp. Other <i>Carex</i> spp. that can be present in low amounts, depending on geographic location, include <i>Carex utriculata, Carex nebrascensis, Carex canescens</i> and <i>Carex saxatilis</i>. Forb cover is variable, from nearly absent to over 25%. Species include <i>Caltha leptosepala, Senecio triangularis, Heracleum maximum, Mentha arvensis, Geum macrophyllum, Epilobium</i> spp., plus many other species, depending on location. Shrubs may be present with 1-5% cover and may include <i>Alnus incana, Symphoricarpos</i> spp., and <i>Salix</i> spp. Trees are rare but can include 1-3% cover of <i>Pinus contorta, Abies lasiocarpa</i>, and <i>Picea engelmannii</i>. |
