This dogwood - willow shrub swamp community is found in the upper midwestern region of the United States and Canada. Stands are found along streams and lakes, or in upland depressions. Hydrology is variable but is typically seasonally flooded. Soils are wet, organic, and minerotrophic, with either highly decomposed peat or fine mineral soils. The vegetation is dominated by tall shrubs between 1 and 3 m tall, with at least 25% cover, and often very dense (>60% cover). More open stands may have high graminoid cover. Trees may be scattered but cover less than 25%. Composition of the shrub layer is quite diverse, primarily due to the diversity of <i>Salix</i> spp., which collectively share dominance with <i>Cornus sericea</i>. Willow species include <i>Salix bebbiana, Salix discolor, Salix eriocephala, Salix interior, Salix fragilis</i>, and <i>Salix petiolaris</i>. Other shrub associates include <i>Cephalanthus occidentalis</i> (southeastward), <i>Cornus amomum, Ribes americanum, Rosa palustris</i> (more common eastward), <i>Rosa blanda</i> and <i>Rosa woodsii var. woodsii</i> (more common westward), <i>Rubus pubescens</i> (northward), <i>Rubus idaeus ssp. strigosus, Sambucus nigra ssp. canadensis, Spiraea alba</i>, and <i>Viburnum lentago</i>. Woody vines present include <i>Clematis virginiana, Parthenocissus quinquefolia</i>, and <i>Toxicodendron radicans</i>. Characteristic herbs include <i>Asclepias incarnata, Symphyotrichum lanceolatum var. lanceolatum, Calamagrostis canadensis, Eutrochium maculatum, Glyceria striata, Impatiens capensis, Lycopus americanus, Lycopus uniflorus, Phalaris arundinacea, Solidago gigantea</i>, and <i>Thalictrum dasycarpum</i>. A variety of sedges may dominate more open stands, including <i>Carex lacustris</i> and <i>Carex stricta</i>. Tree species include <i>Acer rubrum, Fraxinus pennsylvanica</i>, and <i>Ulmus americana</i>. |

This hardstem bulrush - mixed bulrush community type is found mainly in the northeastern Great Plains and northern tallgrass prairie region of the United States and Canada. Stands occur on wetland sites that are flooded for most or all of the growing season. Soils can be largely mineral or contain significant organic matter. Tall graminoids, particularly <i>Schoenoplectus acutus</i> and, less frequently, <i>Bolboschoenus fluviatilis</i>, dominate the vegetation. These two species may grow taller than 2 m and sometimes nearly exclude other species. Other species that can be present include <i>Carex atherodes</i> (especially in the shallower parts of the community), <i>Lemna</i> spp., <i>Schoenoplectus tabernaemontani, Typha latifolia</i>, and <i>Utricularia macrorhiza</i>. <i>Schoenoplectus tabernaemontani</i> can be codominant in places. |

This community type is found in deep marshes throughout the midwestern United States and Canada. The vegetation is dominated by relatively pure stands of <i>Typha</i> spp., either <i>Typha latifolia</i> or <i>Typha angustifolia</i> or both. Many associates could occur. This type may simply be a less diverse variation of ~<i>Typha</i> spp. - <i>Schoenoplectus acutus</i> - Mixed Herbs Midwest Marsh (CEGL002229)$$, or is a ruderal type resulting from human disturbance to wetlands. |

This terrestrial, forb-dominated community is endemic to southeastern and east-central Texas outcrops of the Catahoula Formation. The herbaceous flora of this community is diverse and displays considerable seasonal variation. Occurrences may appear almost devoid of vegetation during the dry summers, while the spring and autumn are periods of peak flowering. The best known and studied examples are found in Jasper County on Angelina National Forest. The community is dominated by prairie-like vegetation with <i>Bigelowia nuttallii, Schizachyrium scoparium, Aristida dichotoma, Aristida longespica, Croton michauxii, Sporobolus silveanus</i>, and <i>Tridens strictus</i> as primary components. Key diagnostic species of this community are typically rare elsewhere in eastern Texas, including <i>Schoenolirion wrightii, Evolvulus sericeus, Callirhoe</i> sp., <i>Gratiola flava, Saxifraga texana, Bigelowia nuttallii, Liatris punctata var. mucronata, Krameria lanceolata</i> and others. Within the Pineywoods vegetation area this community occurs within a matrix of historically longleaf pine-dominated open woodlands. In Walker and Grimes counties (within the Post Oak Savanna vegetation area), this matrix vegetation is replaced by <i>Quercus stellata</i> woodland or savannas and may include a complex of exposed sandstone/mudstone flats and ledges, intermixed with dense, herbaceous patches, scattered, stunted trees and shrubs, and fruticose lichens. Much of the soil and rock is unvegetated. |

This limestone - dolostone moist cliff community occurs in localized areas throughout the central midwestern-interior United States and southern Ontario, Canada. The cliffs are often very steep and found along rivers and strongly dissected hills. The aspect is typically northern and east, but is variable. Soils are generally absent, except on ledges or shelves. The cliff is moist due to seepage or shading due to aspect. The vegetation is generally quite sparse (<25% cover). Trees, when present, are scattered. Shrubs, herbs, and nonvascular species are more often present. Characteristic trees include <i>Acer saccharum</i>. Characteristic shrubs include <i>Hydrangea arborescens</i> and <i>Staphylea trifolia</i>. Common ferns include <i>Adiantum pedatum, Asplenium rhizophyllum</i>, and <i>Cystopteris bulbifera</i>, as well as <i>Asplenium ruta-muraria</i> and <i>Asplenium resiliens</i>. Other herbs include <i>Aquilegia canadensis, Chenopodium simplex, Lysimachia quadriflora, Parnassia grandifolia, Pilea pumila, Selaginella apoda, Solidago caesia</i>, and <i>Solidago flexicaulis</i>. Mosses, liverworts and lichens are also present. |

This type represents bald-cypress - water tupelo swamp forests found in the Mississippi River Alluvial Plain and adjacent areas of the Gulf Coastal Plain of the southern United States, apparently extending northeast to the Interior Low Plateau. Stands are characterized by the presence of shallow standing water all or most of the year. The vegetation contains mixed dominants of <i>Taxodium distichum</i> and <i>Nyssa aquatica</i>. <i>Taxodium</i> is often emergent in the overstory above shorter individuals of <i>Nyssa aquatica</i>. In some instances <i>Carya aquatica</i> and (rarely) <i>Quercus lyrata</i> may also be present. Dominant trees exhibit tall, straight growth and swelled buttresses. The subcanopy is sparse, consisting primarily of <i>Forestiera acuminata, Cephalanthus occidentalis</i>, and <i>Planera aquatica</i>. Shrubs may include <i>Cephalanthus occidentalis</i> and <i>Itea virginica</i> with a variety of other species, such as <i>Acer rubrum var. drummondii, Acer negundo, Cornus obliqua, Fraxinus pennsylvanica, Ilex decidua</i>, and <i>Liquidambar styraciflua</i>, mostly occurring around the slough margins. Woody vines are uncommon but may include <i>Nekemias arborea</i> and <i>Berchemia scandens</i>. The herbaceous layer is also very sparse, being restricted to rotting logs, buttresses of trees, and small mounds and ridges which remain dry most of the growing season. |

This northern hardwoods community type occurs in the western and central Great Lakes area of the United States and Canada. Stands are found on moderate to deep (60->150 cm) sandy loam, clay loam, or loamy sand soils. The soils are typically slightly acidic to circumneutral, dry-mesic to wet-mesic and moderately nutrient rich. Most stands develop on flat to moderate slopes over glacial till. The community is dominated by deciduous trees with scattered conifers in some stands. <i>Acer saccharum</i> is a dominant throughout the range of this community. It may form nearly pure stands. Other common canopy trees include <i>Acer rubrum, Betula alleghaniensis, Fraxinus americana</i>, and <i>Tilia americana</i>. Boreal conifers such as <i>Abies balsamea</i> and <i>Picea glauca</i> are essentially lacking, but <i>Pinus strobus, Thuja occidentalis</i>, and <i>Tsuga canadensis</i> can be found in some stands. The shrub layer is typically sparse; however, it can be moderately developed where the tree canopy is not fully closed. Typical shrubs include <i>Acer spicatum, Corylus cornuta, Lonicera canadensis</i>, and <i>Taxus canadensis</i>. The herbaceous stratum includes <i>Clintonia borealis, Dryopteris carthusiana, Lycopodium</i> spp., <i>Maianthemum canadense, Maianthemum racemosum, Osmorhiza claytonii, Polygonatum pubescens, Streptopus lanceolatus var. longipes</i>, and <i>Viola</i> spp. Diagnostic features include the deciduous hardwood dominance, the lack of <i>Fagus grandifolia</i>, and the presence of a typical northern hardwood ground layer. |

This subboreal aspen - birch forest type is found in the north-central United States and southern Canada on a variety of mesic upland locations. This community has been found on rich sites over clay or silt loam soils. Deciduous trees dominate the canopy and tree reproduction layers of this community. Conifers, when present, are widely scattered. Tree density is moderate to high, but substantial light penetrates the canopy due to the growth form of the dominant species, <i>Betula papyrifera</i> and <i>Populus tremuloides</i>. Other northern hardwoods may be found in the canopy but are more common in the sapling layer. These include <i>Acer rubrum, Acer saccharum, Betula alleghaniensis, Fraxinus pennsylvanica, Ostrya virginiana, Quercus rubra, Tilia americana</i>, and <i>Ulmus americana</i> (in more mesic sites). <i>Fagus grandifolia</i> and <i>Tsuga canadensis</i> become more common in eastern examples of this type. The shrub stratum is usually not well-developed due to shading from the canopy and subcanopy trees. Scattered <i>Acer spicatum, Corylus cornuta, Diervilla lonicera</i> and <i>Rubus pubescens</i> are typical shrubs. <i>Taxus canadensis</i> and <i>Acer pensylvanicum</i> are present on some sites. The herbaceous layer contains species such as <i>Aralia nudicaulis, Eurybia macrophylla, Clintonia borealis, Maianthemum canadense, Oryzopsis asperifolia</i>, and <i>Streptopus lanceolatus var. longipes</i>. Mosses include <i>Dicranum flagellare, Dicranum montanum</i>, and others. |
