This wild rice marsh community is found in the upper midwestern United States and adjacent Canada. Stands are found in deeper, sheltered waters of slow-moving streams, protected bays, and flowage lakes, particularly at stream mouths. Water depths generally exceed 0.5 m. Substrate is rich sedimentary peat, or mucky, silty soils. A thick mat of rice stalks often covers the bottom. The marsh is dominated almost entirely by the tall emergent graminoids <i>Zizania aquatica</i> or <i>Zizania palustris</i>. Floating-leaved and submerged aquatic cover can be high, but species composition is variable. Species include <i>Ceratophyllum demersum, Nuphar variegata (= Nuphar lutea ssp. variegata), Potamogeton natans, Potamogeton zosteriformis, Spirodela polyrrhiza, Utricularia macrorhiza (= Utricularia vulgaris)</i>, and others. |

These forests occur mostly on the west side of the southern Oregon Cascades, but may also occur in California. Sites occur between 760-1520 m (2500-5000 feet) elevation on moderate slopes on all aspects. Most examples of this giant, low- to mid-elevation mixed-conifer forest association usually represent second- or third-growth logged forest stands. Old remnants are extremely rare. The tree canopy is codominated by Pseudotsuga menziesii, Calocedrus decurrens, Pinus lambertiana, and Abies concolor. Shrub cover averages 31-100%, and in most stands is very dense. Mahonia nervosa (= var. nervosa), Symphoricarpos mollis, Gaultheria shallon, Rosa gymnocarpa, and Rhododendron macrophyllum are common shrubs. Herbaceous cover ranges 4-77% with an average of 29%. Common herbs include Achlys triphylla, Linnaea borealis ssp. longiflora, Goodyera oblongifolia, Anemone deltoidea, and Synthyris reniformis. Grass cover is very low (1%). |

This community is known only from North Carolina but may possibly be found in Virginia, South Carolina or Georgia. These forests occur in very gently-sloped upper drainages in flat Piedmont terrain with dense clay hardpan soils that have restricted internal drainage. Restricted rooting depth, shallow ponding of water on the surface, and short-duration flood flows appear to be important environmental factors. The canopy is a mix that includes both wetland and upland species. Generally <i>Quercus phellos</i> or <i>Quercus michauxii</i> are abundant. The most abundant upland species tend to be <i>Quercus alba</i> and <i>Carya carolinae-septentrionalis</i>. <i>Liquidambar styraciflua</i> and <i>Acer rubrum</i> may also be common. Other canopy species may include <i>Carya ovata, Ulmus americana</i>, and <i>Fraxinus</i> sp. <i>Platanus occidentalis, Celtis laevigata</i>, or other alluvial species may be present but generally only in very small numbers. The understory consists of canopy species, plus <i>Nyssa sylvatica</i>. Shrubs are sparse, but vines, especially <i>Smilax rotundifolia</i>, may be prominent. The herbaceous layer is generally dense, though it may be locally sparse. Herb diversity is high and includes both wetland and upland species. Wetland <i>Carex</i> spp., <i>Danthonia spicata</i>, and <i>Glyceria striata</i> are abundant. Invasive exotic plants of floodplains, such as <i>Microstegium vimineum</i> and <i>Lonicera japonica</i>, are often present. The shallow stream channels are, at least sometimes, lined with <i>Isoetes</i> sp. |

The vegetation in this alliance occurs at middle elevations (800-2000 m) of the Intermountain West, usually in washes, on cliffs, or on steep, rocky terrain. Precipitation averages 20-45 cm annually. These communities occur on skeletal soils derived from granitic or sedimentary parent materials. In central Utah the alliance is associated with limestone. These shrublands are dominated by ~Purshia mexicana$, an erect evergreen shrub that grows up to 8 m tall, or ~Purshia stansburiana$. Associated shrubs include ~Ericameria nauseosa (= Chrysothamnus nauseosus), Coleogyne ramosissima, Artemisia tridentata$, and ~Yucca baccata$. The herbaceous ground layer is typically sparse, but can be moderately dense in stands which have been invaded by non-native annual grasses. Typical native species include ~Sporobolus cryptandrus, Poa secunda$, and ~Pseudoroegneria spicata$. Adjacent vegetation is usually ~Pinus - Juniperus$ woodlands, ~Quercus gambelii$ shrublands, or ~Artemisia tridentata$ shrublands. |
