This wet meadow community occurs on gently sloping stream benches and terraces on small streams. All reported stands occur on alluvial surfaces. Elevation ranges from 1920 to 3570 m (6300-11,700 feet). Soils are mineral with fine textures ranging from sandy to silts to clayey. Some soils have an organic layer. This herbaceous meadow type is dominated by <i>Carex microptera</i>. Other sedges are typically present in lower abundances and include <i>Carex aquatilis, Carex utriculata, Carex praegracilis</i>, and <i>Carex pellita</i>. Other graminoids that can have significant cover include <i>Juncus hallii, Juncus longistylis, Deschampsia cespitosa, Festuca idahoensis</i>, and <i>Poa pratensis</i>. Forbs are few and include <i>Symphyotrichum foliaceum, Fragaria virginiana, Geum macrophyllum, Argentina anserina, Arnica chamissonis var. andina, Eurybia integrifolia</i>, and <i>Hymenoxys hoopesii</i>. Disturbed stands can have <i>Agrostis scabra, Phleum pratense</i>, and <i>Taraxacum officinale</i>. |

Habitat is depressions and seepy alluvial fans in subalpine heath. Stands of this association occur in transitional areas between the slightly wetter ~<i>Carex nigricans</i> Wet Meadow (CEGL001816)$$ and slightly drier associations of <i>Carex spectabilis</i> and upland <i>Phyllodoce</i> heath, and intergrade with both. Stands on alluvial fans occur below springs and seeps and may be laced with rivulets and or irrigated by sheetflow. Trees are absent. Shrubs are sparse, <i>Salix commutata</i> being the most abundant in 25% of the plots, but with a very low cover. <i>Carex scopulorum</i> is the primary herbaceous species with an average cover of 49% and ranging from 10-90%. Other species with significant patches include <i>Deschampsia cespitosa, Eleocharis quinqueflora, Muhlenbergia filiformis, Eleocharis palustris</i>, and <i>Juncus arcticus ssp. littoralis</i>. The other 40 species occur at low constancy and cover and are mostly wetland taxa indicative of perennial saturation. |

This sago pondweed - water-milfoil pond community is found in glacial ponds in the northwestern Great Plains of the United States and Canada. These ponds occur at elevations ranging from 1250 to 1525 m (4100-5000 feet). Stands occur in the permanently inundated, deep water zone of glacial ponds in gently rolling, glacial terrain. Water is usually 15-100 cm deep. The type can occur in fresh to brackish water, but is characteristic of mildly brackish water. Underlying parent material is mixed sedimentary (partly calcareous) glacial till or lacustrine deposits. Pond bottoms are composed of clayey mud or mud mixed with gravel and stones. The vegetation is characteristically poor in species, and canopy cover is low to moderate, being occasionally up to 70% . Submerged aquatic macrophytes dominate the vegetation. <i>Stuckenia pectinata</i> is present in all stands sampled; <i>Myriophyllum spicatum</i> or <i>Myriophyllum sibiricum</i> can be locally dominant and was present in most stands. <i>Ranunculus aquatilis, Utricularia macrorhiza, Sagittaria cuneata</i>, and <i>Potamogeton richardsonii</i> are occasionally present. <i>Chara</i> sp., a calciphile macroalga, is often present. |

This white pine - red maple swamp forest is found in the southern Great Lakes region of the United States and Canada, ranging east in scattered locations. Stands occur on sites with at least a thin layer of organic material on the surface. Glacially deposited sand usually lies beneath the organic layer. The overstory is dominated by <i>Pinus strobus</i> and may contain <i>Acer rubrum, Betula alleghaniensis, Tsuga canadensis</i>, and <i>Ulmus americana</i>. Shrubs can be sparse but include <i>Alnus incana</i> and <i>Ilex verticillata</i>. Understory species include <i>Carex</i> spp., <i>Osmunda cinnamomea, Osmunda regalis</i>, and <i>Symplocarpus foetidus</i>. <i>Sphagnum</i> spp. may occur as a ground cover. In Wisconsin, common species include <i>Carex folliculata</i> and <i>Thelypteris simulata</i>, which are more common in the eastern United States. |

This paper birch / beaked hazelnut forest type is found in the northwestern Great Plains and Black Hills of the United States. Stands occur on nearly level ground to steep north-facing slopes with silt loam soil. This community has a predominantly closed canopy dominated by <i>Betula papyrifera</i>. Other trees that may contribute significantly to the canopy are <i>Quercus macrocarpa, Populus tremuloides</i>, and, in the Bear Lodge Mountains, <i>Pinus ponderosa</i>. <i>Fraxinus pennsylvanica</i> may be present, especially as small trees or saplings. There is a tall-shrub layer that usually reaches 2 m or more. The most abundant shrub is <i>Corylus cornuta</i>. Other species found in this layer are <i>Amelanchier alnifolia</i> and <i>Prunus virginiana</i>. There is a low-shrub layer that consists of <i>Symphoricarpos</i> spp., <i>Spiraea betulifolia, Shepherdia argentea</i>, and <i>Ribes</i> spp. Common herbaceous species include <i>Actaea rubra, Maianthemum canadense, Carex</i> spp., <i>Aralia nudicaulis, Apocynum androsaemifolium</i>, and <i>Schizachne purpurascens</i>. |

This swamp chestnut oak - hardwood forest is a bottomland community found in the central and south-central United States along borders and first bottoms of rivers, streams, and swamps, particularly along the Mississippi River, Ohio River, Tennessee River and their tributaries. Soils which support this association are deep, moist, rich, loamy, typically somewhat acidic to circumneutral, and well-drained. Short periods of inundation in the fall and winter can occur. Canopy diversity can be high in this community. Stands are typically dominated by <i>Quercus michauxii, Quercus shumardii, Liquidambar styraciflua</i>, and <i>Carya laciniosa</i>. Other hickories which can be present include <i>Carya ovata</i> and <i>Carya tomentosa</i>. Canopy closure is at or near 100%. The subcanopy is dense and dominated by <i>Carpinus caroliniana</i> and <i>Ulmus alata</i>. Dominant shrubs include <i>Ilex decidua, Cornus foemina</i>, and <i>Viburnum dentatum</i>. The herbaceous layer is dense and dominated by <i>Carex</i> spp. and a diverse and varied assemblage of grasses and forbs, including <i>Arundinaria gigantea</i> which often forms dense, almost impenetrable stands particularly where canopy openings allow sunlight to reach the forest floor. Vines are prevalent in the subcanopy and understory of this community; the most commonly encountered are <i>Toxicodendron radicans, Campsis radicans</i>, and <i>Parthenocissus quinquefolia</i>. |

These upland <i>Pinus taeda - Quercus stellata</i>-dominated communities occur in the Gulf Coastal Plain, most frequently west of the Mississippi River. Depending upon management history, these stands range from open and woodland-like to fairly closed and dense. The understory varies accordingly from viney (<i>Toxicodendron radicans, Gelsemium sempervirens, Parthenocissus quinquefolia</i>, etc.) to herbaceous (<i>Schizachyrium scoparium</i>, with plentiful legumes and asters). Several <i>Crataegus</i> spp. are often present in the shrub layer of these stands, possibly indicating the rich nutrient status of the soils. |

This association occurs in the Rolling Plains over deeper soils and is likely to occur also in the northern Edwards Plateau and Lampasas Cutplain of Texas. This association is dominated by <i>Prosopis glandulosa</i>. <i>Rhus lanceolata</i> may codominate, especially after fire. Other woody species, such as <i>Sideroxylon lanuginosum</i>, may be present in low abundance. <i>Nassella leucotricha</i> grows primarily under the shade of the <i>Prosopis glandulosa</i>, along with <i>Bouteloua</i> and other grasses (composition dependent on grazing pressure). Other woody species, such as <i>Sideroxylon lanuginosum</i>, may be present in low abundance. The understory is usually dominated by <i>Nassella leucotricha</i>; <i>Bouteloua curtipendula</i> is often uncommon or absent. Other common understory species include <i>Ruellia nudiflora, Croton monanthogynus, Rhynchosia senna, Schizachyrium scoparium, Symphyotrichum ericoides, Desmanthus leptolobus, Stenaria nigricans, Indigofera miniata</i>, and <i>Liatris punctata var. mucronata</i>. This is apparently a natural type, but it may closely resemble semi-natural vegetation in composition and structure. |
