This association is a semi-natural type, consisting of <i>Typha latifolia</i> as an essentially monospecific stand, especially in artificial wetlands, such as borrow pits or ponds. The water table is at or above the soil surface for at least part of the growing season. The dominant species, <i>Typha latifolia</i>, often forms dense, almost monotypic stands. <i>Carex</i> spp. and <i>Schoenoplectus</i> spp. often found in this community, especially on the margins. Other co-occurring species of this association are not fully understood. It is a widespread type. In the Interior Low Plateau of Tennessee, <i>Typha latifolia</i> is commonly found with <i>Scirpus cyperinus</i> in roadside ditches and on the margins of ponds and reservoirs. |

This community type occurs in the northwestern Great Plains of the United States. Stands occur in upland ravines and broad valleys or on moderately steep slopes. They also occurs along small permanent or ephemeral streams, including deep mesic ravines and canyon bottoms that are not flooded or saturated. On these sites, soil and topography permit greater than normal moisture. The soils are clay loams, sandy clay loam, and sandy loam, dry to moist, and moderately well-drained. The parent material is typically colluvium or alluvium. This community is an open- to closed-canopy woodland dominated by <i>Fraxinus pennsylvanica</i>. <i>Ulmus americana</i> or <i>Acer negundo</i> sometimes achieve codominance. In undisturbed stands, the understory is composed of two layers. The taller and more conspicuous layer is a shrub layer 2-3 m tall. This layer is dominated by <i>Prunus virginiana</i> with smaller amounts of <i>Symphoricarpos occidentalis</i> or more rarely <i>Ostrya virginiana</i>. The lower layer is dominated by grasses and sedges such as <i>Elymus virginicus, Elymus villosus</i>, and <i>Carex sprengelii</i>. Common herbaceous species include <i>Aquilegia canadensis, Cerastium arvense, Thalictrum dasycarpum, Galium boreale, Galium aparine, Maianthemum stellatum</i>, and <i>Thalictrum dasycarpum</i>. The continuation of the status of <i>Ulmus americana</i> as a prominent part of this community is uncertain due to the effects of Dutch elm disease. |

This Rocky Mountain juniper community type is found in the western Great Plains of the United States. Stands occur almost exclusively on steep (30-70%) north-facing slopes. The soils are shallow and poorly developed; loamy sands and sandy loams predominate. The vegetation is an evergreen woodland with moderately open to dense cover of <i>Juniperus scopulorum, Juniperus virginiana</i>, or introgressant hybrids of the two. Woody species other than <i>Juniperus scopulorum</i> or <i>Juniperus virginiana</i> occur sporadically, but none achieves prominence. Most of the trees are small (10-20 cm dbh) and few exceed 6 m. Where the density of the tree canopy is high, the short-shrub and herbaceous strata are not well-developed. In more open places <i>Piptatheropsis micrantha</i> is often abundant. Other common herbaceous species include <i>Campanula rotundifolia, Galium boreale</i>, and <i>Maianthemum stellatum</i>. Mosses and lichens can cover much of the ground. |

This mesic buffaloberry shrubland is found in the northern Great Plains of the United States and Canada, and on the western slope of Colorado south to the Paunsaugunt Plateau, Utah. Stands occur on stream terraces, rolling uplands, and badlands, and where moisture is more plentiful than the surrounding landscape, such as in swales, ravines, near streams and ditches, and on northwest- to east-facing slopes. The vegetation is dominated by a moderate to dense canopy of medium-tall shrubs. The most abundant of these, <i>Shepherdia argentea</i>, is typically 1.5-3 m tall. Other common shrub species are <i>Juniperus horizontalis, Prunus virginiana, Ribes</i> spp., <i>Rhus aromatica, Rosa woodsii</i>, and <i>Symphoricarpos occidentalis</i>. Graminoids and forbs may have only half the cover of the shrub layer and are quite variable. Graminoids include <i>Poa pratensis, Pascopyrum smithii</i>, and <i>Bromus</i> spp. Common forbs are <i>Achillea millefolium, Artemisia ludoviciana</i>, and <i>Parietaria pensylvanica</i>. This community occurs in the landscape as either narrow bands along streams or in small thickets. |

This riparian willow shrubland is found in the montane regions and western plains of the United States, and also along the eastern Front Range of the Rocky Mountains in Alberta. This community is a briefly flooded scrub-shrub wetland on slightly to moderately alkaline soils, usually near low-gradient streams. This shrubland is typically dominated by a dense growth of shrubs 0.5-3 m tall. The most abundant species in the shrub layer are <i>Salix bebbiana, Salix scouleriana</i>, and <i>Salix lucida ssp. caudata</i>. Other species found in this stratum include <i>Betula occidentalis, Cornus sericea ssp. sericea, Salix exigua, Salix melanopsis, Salix lutea, Salix prolixa, Amelanchier alnifolia</i>, and <i>Prunus virginiana</i>. A shorter shrub layer is sometimes present, with <i>Symphoricarpos occidentalis, Ribes inerme, Lonicera involucrata</i>, and <i>Rosa acicularis</i>. The herbaceous layer can be very abundant and predominantly graminoids; common species include <i>Schoenoplectus</i> spp. and/or <i>Scirpus</i> spp., <i>Carex</i> spp., <i>Triglochin palustris, Calamagrostis canadensis, Bromus carinatus, Poa palustris</i>, and <i>Equisetum</i> spp. along the wetter margins of the community. Forbs can be abundant and variable in composition, ranging from mesic-site forbs to ones adapted to drier conditions. Species include <i>Heracleum maximum, Cicuta maculata, Geranium richardsonii, Geum macrophyllum, Gentianella amarella ssp. acuta, Prunella vulgaris, Pyrola asarifolia, Zizia aptera, Sanicula marilandica, Viola canadensis, Vicia americana</i>, and <i>Ranunculus macounii</i>. |

This is a widespread mountainous riparian association known from lakeshores, floodplains, riparian zones, and wet meadows at elevations ranging from 707 to 3110 m (2320-10,200 feet). This association occurs from Colorado to Montana west to Washington and most often occurs in valley bottom positions, ranging from relatively narrow montane valleys to wide glacial troughs. Stands can be long narrow strings along steep-gradient streams or wide willow shrublands. Soils are usually well-developed but poorly drained, dark-colored silty clay loams. These soils often have much organic material intermixed and overlie deposits of gravel and rocks. Soils can occasionally be well-drained, gravelly loamy sands. It is characterized by a dense canopy of <i>Salix drummondiana</i> and a thick undergrowth of <i>Calamagrostis canadensis</i>. Stands are often associated with beaver activity. |

This community includes non-alluvial, wetland vegetation at very high elevations (1170-1490 m [3850-4900 feet]) in the southern Appalachian Mountains. It is known only from the valley of Long Hope Creek, Ashe and Watauga counties, North Carolina, where about 20 examples occur, and from Mount Rogers, Grayson County, Virginia. This palustrine shrubland is known to occur over amphibolite (a mafic metamorphic rock) and over rhyolite (a felsic igneous rock), on slight to fairly steep slopes (1-15%), is slightly to strongly seepage-fed, and generally has shallow soils over bedrock. Examples are structurally variable, but usually have greater than 25% shrub cover (ranges to 100%). The vegetation generally consists of a mosaic of shrub thickets and small herb-dominated areas, much of it underlain by <i>Sphagnum</i> mats. <i>Sphagnum</i> coverage is 50-100%. Trees such as <i>Picea rubens, Abies fraseri, Pinus strobus</i>, and <i>Tsuga canadensis</i> may be scattered throughout or may dominate in patches or on the edges. Dominant shrubs include <i>Salix sericea, Viburnum nudum var. cassinoides, Ilex collina, Rhododendron catawbiense</i>, and <i>Rhododendron maximum</i>. Other characteristic species include <i>Taxus canadensis</i> (Long Hope Valley only), <i>Picea rubens, Rosa palustris, Salix humilis, Carex atlantica, Carex baileyi, Carex echinata, Carex gynandra, Carex leptalea, Carex lurida, Carex trisperma, Eriophorum virginicum, Galium asprellum, Houstonia serpyllifolia, Juncus effusus, Osmunda cinnamomea, Oxypolis rigidior, Rhynchospora capitellata, Scirpus cyperinus, Scirpus expansus, Scirpus polyphyllus, Packera aurea, Solidago patula var. patula, Sphagnum fuscum, Sphagnum recurvum</i>, and <i>Rhizomnium appalachianum</i>. |
