This herbaceous wetland association is found throughout much of the western U.S. Stands occur in montane and subalpine areas around the edges of lakes and beaver ponds, along the margins of slow-moving reaches of streams and rivers, and in marshy swales and overflow channels on broad floodplains. Sites are flat to undulating, often with a hummocky microtopography. The water table is usually near the surface for most of the growing season. There are a wide variety of soil types for this association. The vegetation is characterized by a moderately dense to dense perennial graminoid layer dominated or codominated by <i>Carex utriculata</i> (20-99% cover). Stands often appear to be nearly pure <i>Carex utriculata</i>, but a variety of other graminoid species may be present as well. Other <i>Carex</i> species present include <i>Carex aquatilis, Carex canescens, Carex lenticularis, Carex aquatilis</i>, and <i>Carex microptera</i>, but usually with low cover. Other graminoid species that may be present include <i>Calamagrostis canadensis, Eriophorum angustifolium, Glyceria striata</i>, and <i>Juncus arcticus ssp. littoralis</i>. The sparse forb cover can include <i>Geum macrophyllum, Fragaria virginiana, Mentha arvensis</i>, and <i>Mimulus guttatus</i>. Scattered <i>Salix</i> spp. shrubs may be present because these riparian shrublands are often adjacent. <i>Salix</i> species vary depending on elevation and geography. This association is distinguished from <i>~Carex aquatilis - Carex utriculata</i> Wet Meadow (CEGL001803)$$ by the dominance of <i>Carex utriculata</i>. <i>Carex aquatilis</i>, if present, is not more than one-third of the total cover. |

This association represents upland depression swamps found in the Piedmont of the Carolinas, Virginia, and the Potomac Valley region of Maryland. It also occurs in limited areas of the adjacent Inner Coastal Plain of the Carolinas. Examples are usually dominated by an almost pure canopy of <i>Quercus phellos</i>, sometimes with codominant <i>Quercus lyrata</i> or <i>Liquidambar styraciflua</i>; scattered individuals of other tree species may be present. Shrubs are generally sparse and not particularly diagnostic of this community. The most characteristic component of the understory are wetland sedges such as <i>Carex albolutescens, Carex intumescens</i>, and <i>Carex joorii</i>, but a number of other species may also be encountered. <i>Sphagnum lescurii, Climacium americanum</i>, and <i>Polytrichum</i> spp. are important moss species. These ponds are important amphibian breeding areas. |

This shrubland association occurs on moderately steep to very steep northwest- and northeast-facing slopes at low elevations between 24 and 472 m. It is characterized by a codominance of <i>Artemisia californica</i> and <i>Salvia leucophylla</i> in the shrub layer, with no distinguishing species in the herbaceous layer. The emergent tree layer is generally absent but can include <i>Quercus agrifolia, Quercus lobata</i>, or <i>Juglans californica</i>. |

This association represents intermediate and basic, mesic, mixed hardwood forests of the Piedmont, ranging from south-central Virginia south to Georgia. Stands of this association are closed-canopy forests dominated by <i>Fagus grandifolia</i> and <i>Quercus rubra</i> with <i>Liriodendron tulipifera, Quercus alba, Carya ovata</i>, and <i>Fraxinus americana</i>. In addition, <i>Acer floridanum</i> or <i>Acer leucoderme</i> may be present within their ranges. <i>Acer floridanum</i> dominates the canopy of some stands. Prominent understory species include <i>Aesculus sylvatica, Ostrya virginiana</i>, and <i>Asimina triloba</i>. Herbs which appear to be abundant or characteristic include <i>Polystichum acrostichoides, Asarum canadense, Actaea racemosa, Adiantum pedatum, Sanguinaria canadensis, Tiarella cordifolia var. collina, Carex laxiflora var. laxiflora, Carex grisea, Desmodium pauciflorum, Uvularia sessilifolia, Maianthemum racemosum, Polygonatum biflorum, Tipularia discolor, Dicentra canadensis, Podophyllum peltatum, Cardamine concatenata, Erythronium americanum</i>, and <i>Erythronium umbilicatum ssp. umbilicatum</i>. |

This shrubland association occurs on moderately steep to very steep slopes of variable aspect at low elevations between 0 and 460 m. It is characterized by <i>Artemisia californica</i> and <i>Eriogonum cinereum</i> in the shrub layer. The herbaceous layer is generally insignificant but does include several native species of grasses. The emergent tree layer is generally absent but may include <i>Quercus agrifolia</i> and <i>Juglans californica</i>. |
