This association is known from the Point Reyes National Seashore and from Suisun Marsh in California. Information about its global characteristics is not available without additional inventory. Other anecdotal observations in San Pablo Bay and San Francisco Bay suggest that it regularly occupies the outer edges of tidal mudflats in the areas with deepest tidal water. <i>Salicornia depressa</i> typically occupies the landward edges of the stands. This association is found on flat, linear/even basins/wetlands with no slope. It occurs on medium silt soil textures and silty alluvium parent material. Typically stands are monotypes with <i>Spartina foliosa</i> comprising most or all of the vegetative cover, occasionally with some minor cover of <i>Salicornia depressa</i> and algae. |

This red maple swamp forest type is found in the northern parts of the Great Lakes region of the United States and in adjacent Canada. Stands are typically found on muck and shallow peat on lakeplains and floodplains. The canopy structure is variable, with cover ranging from open (25-60%) to closed (60-100%). Common canopy dominants include <i>Acer rubrum, Betula alleghaniensis, Betula papyrifera, Fraxinus nigra, Fraxinus pennsylvanica</i>, and occasional <i>Larix laricina, Pinus strobus</i>, and <i>Ulmus americana</i> (at least historically). <i>Pinus strobus</i> may form a patchy supercanopy above the hardwood canopy. Common shrubs include <i>Alnus incana</i>. <i>Toxicodendron vernix</i> may be common in parts of the range. Other associates include <i>Ilex verticillata, Ribes</i> spp., and <i>Rubus idaeus ssp. strigosus</i>. The herbaceous layer contains <i>Carex stipata, Impatiens capensis, Mitella nuda, Onoclea sensibilis, Osmunda cinnamomea, Osmunda claytoniana, Saxifraga pensylvanica</i>, and others. A seepage swamp subtype can occur where steep sandy slopes and gravelly slopes merge with a river or stream terrace. The ground layer can be exceptionally diverse, with characteristic seepage species including <i>Angelica atropurpurea, Carex bromoides, Hydrocotyle americana, Poa paludigena, Saxifraga pensylvanica</i>, and <i>Symplocarpus foetidus</i>. |

This community occurs on gently sloping to nearly flat areas in the eastern Edwards Plateau and Crosstimbers of Texas and ranges into southern Oklahoma. <i>Quercus fusiformis</i> is the canopy dominant, occurring from locally dense mottes to very open woodland (savanna) structure. With fire suppression, grazing, and other disturbances, <i>Juniperus ashei</i> has increased and forms a dense lower tree stratum in many sites. Other characteristic shrubs and small trees include <i>Diospyros texana, Mahonia trifoliolata, Forestiera pubescens</i>, and <i>Celtis laevigata var. reticulata</i>. In areas with no or mild grazing pressure, <i>Schizachyrium scoparium var. scoparium</i> is typically the dominant grass, often admixed with <i>Bouteloua rigidiseta, Bouteloua curtipendula, Bouteloua hirsuta var. pectinata, Aristida purpurascens</i>, and <i>Nassella leucotricha</i>. Other herbs include <i>Chaetopappa bellidifolia, Evolvulus sericeus, Lygodesmia</i> sp., and others. When impacted by intense grazing, the grass dominants may shift toward the mid to short grasses that are less desirable forage. The herbaceous layer in some areas is increasingly becoming dominated by the exotic grass <i>Bothriochloa ischaemum</i>. |

These mixed woodlands occur on the higher terraces along floodplains of larger streams and in the riparian corridors of smaller intermittent or ephemeral streams, primarily within the Edwards Plateau, South Texas Plains, and eastern Trans-Pecos of Texas. <i>Quercus fusiformis</i> is usually dominant, but other important species may include <i>Celtis laevigata var. reticulata, Carya illinoinensis, Fraxinus albicans, Fraxinus berlandieriana</i> (within its range), <i>Ulmus crassifolia, Quercus macrocarpa, Juniperus ashei</i>, and <i>Diospyros texana</i>. More mesic floodplains are dominated by <i>Carya illinoinensis - Celtis laevigata</i> woodlands or <i>Celtis laevigata - Ulmus crassifolia</i> woodlands. Adjacent slopes may be dominated by woodlands, savanna, and shrublands. |

This bluestem tallgrass prairie type is found in the unglaciated regions of the northwestern Great Plains of the United States. Stands occur on lower slopes and bottomlands of narrow gullies and draws. It requires more moisture than is generally provided by direct precipitation. The extra water comes from runoff from upslope areas and meltwater from snow which often accumulates in drifts on this community. The soil is loam to sandy loam and moderately deep to deep. The vegetation is dominated by moderately dense to dense tall and mid grasses. Most of the species are 0.7-1.5 m tall. Common grasses are <i>Andropogon gerardii, Bouteloua curtipendula, Schizachyrium scoparium, Sporobolus heterolepis</i>, and <i>Hesperostipa spartea</i>. Other grasses that may occur include <i>Elymus trachycaulus, Carex pensylvanica</i>, and <i>Panicum virgatum</i>. Forbs such as <i>Artemisia ludoviciana, Echinacea angustifolia, Helianthus pauciflorus ssp. pauciflorus, Avenula hookeri, Juncus arcticus ssp. littoralis, Liatris scariosa</i>, and <i>Lilium philadelphicum</i> are common. Shrubs, especially <i>Symphoricarpos occidentalis</i>, are often present but never abundant. |

This community is found throughout the central and upper midwestern United States where it is found along large rivers and lakeshores. Sites are subject to seasonal flooding that typically draws down by late summer. The diagnostic dominant is <i>Bolboschoenus fluviatilis</i>, which often forms almost mono-dominant patches. Other marsh associates include <i>Typha angustifolia, Typha latifolia, Schoenoplectus tabernaemontani</i>, and <i>Sparganium eurycarpum</i>. |

This sedge - reedgrass wet meadow is found in the northern Great Plains. Stands occur on level ground in shallow depressions and other lowlands on poorly drained sandy, loamy, or silty clay soils. Standing water may be present for a few to several weeks during most years. Soil pH is circumneutral to somewhat alkaline and organic content can be moderately high. The vegetation of this community provides approximately 100% cover and the dominant vegetation is graminoids, typically 0.5-1.0 m tall. Forbs can be common, but shrubs are rarely found in this type. The most abundant species are <i>Calamagrostis stricta, Carex pellita, Carex sartwellii, Anemone canadensis, Apocynum cannabinum, Symphyotrichum lanceolatum, Eleocharis compressa, Juncus arcticus ssp. littoralis, Phalaris arundinacea, Polygonum amphibium</i>, and <i>Schoenoplectus americanus</i>. <i>Carex buxbaumii</i> may be common, except in North Dakota. |
