This is a moist but well-drained forested association located primarily on north-facing toeslopes, lower and midslopes, near riparian areas and sideslope seepages. It is documented from Idaho, northern Utah, western Wyoming, and Montana. It may occur as a relict in Arizona, but it has not been documented there. This association is found at elevations from 1829 to 3201 m (6000-10,500 feet). Soils are deep and moist. The vegetation is dominated by <i>Abies lasiocarpa</i> and /or <i>Picea engelmannii</i>. <i>Pseudotsuga menziesii</i> and <i>Populus tremuloides</i> are often present. <i>Picea pungens</i> may also co-occur. Stands are typically shrubby (with 5-15% total cover), but no shrub species are consistently present. Common shrub species include <i>Amelanchier, Lonicera, Acer glabrum, Rubus parviflorus, Prunus virginiana</i>, and <i>Symphoricarpos oreophilus</i>. The herbaceous undergrowth is clearly dominated by lush forbs; <i>Actaea rubra</i> is almost always present and abundant, often in small clumps scattered throughout the stand. Other forbs typically present are <i>Arnica cordifolia, Galium triflorum, Osmorhiza berteroi, Aconitum columbianum, Equisetum arvense, Geranium richardsonii, Senecio triangularis, Streptopus amplexifolius</i>, and <i>Thalictrum fendleri</i>. |

This red maple - southern hardwoods bottomland forest type is found in the Mississippi River Alluvial Plain of the United States. Stands occur on the seasonally flooded bottomlands along rivers and large streams. Soils which support this forest are predominantly medium- and fine-textured, clayey, slowly permeable, alluvial sediments deposited in slackwater areas of floodplains. The water regime is characterized by seasonal shallow flooding, although hydrologic conditions are often extremely variable. This variability results in high species diversity at these sites. Acer rubrum and Fraxinus profunda are the dominant overstory species in this community, but Liquidambar styraciflua, Quercus lyrata, Quercus bicolor, and Ulmus rubra occur almost as frequently. Populus heterophylla is an uncommon associate. Acer rubrum and Fraxinus profunda dominate the subcanopy. The shrub layer can include a diverse mixture including Cephalanthus occidentalis, Forestiera acuminata, and Ilex decidua, but Itea virginica is characteristic of this community. Even with dense shading, the herbaceous layer is usually well-developed, displaying a preponderance of Carex spp., Leersia spp., Glyceria spp., with Boehmeria cylindrica, Laportea canadensis, and Pilea pumila. Vitis spp. are characteristic vines of this community, but Toxicodendron radicans and Campsis radicans are also prominent. |

This spruce-fir riparian forest occurs in the southern Rocky Mountains in Colorado. It occurs on heavily forested reaches of first- and second-order streams above 2440 m (8000 feet) in elevation where <i>Abies lasiocarpa - Picea engelmannii</i> forests also occur on adjacent hillslopes. It is found on stream benches and banks in narrow, V-shaped valleys most commonly within 4.6-6.1 m (15-20 feet) of the channel edge and rarely more than 0.6 m (2 feet) above the streambank. Stream channels vary in their morphology; they can be narrow to wide and steep to flat and sinuous. Soils are shallow, dark-colored layers of loamy sands, silty loams, and sandy clay loams over cobbly alluvium with high organic matter content in the top 50.8 cm (20 inches) and mottles at 101.6 cm (40 inches). Stands have an evergreen needle-leaved tree canopy dominated by <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i>. Occasional canopy associates can include <i>Picea pungens, Pinus contorta</i>, or <i>Populus tremuloides</i>. Tall <i>Alnus incana</i> and <i>Salix drummondiana</i> grow in a thick band along the edge of the stream. At lower elevations, <i>Alnus incana</i> is more abundant than <i>Salix drummondiana</i>. At mid elevations, the two shrubs can be codominant. At higher elevations, <i>Salix drummondiana</i> becomes dominant and <i>Alnus incana</i> drops out, forming ~<i>Abies lasiocarpa - Picea engelmannii / Salix drummondiana</i> Forest (CEGL000327)$$. In stands where <i>Alnus incana</i> and <i>Salix drummondiana</i> codominate the shrub layer, the stand should be classified as ~<i>Abies lasiocarpa - Picea engelmannii / Salix drummondiana</i> Forest (CEGL000327)$$. Additional tall shrubs that can occur in this association include <i>Cornus sericea, Salix geyeriana, Salix monticola, Lonicera involucrata</i>, and <i>Acer glabrum</i>. The herbaceous layer is usually rich in forb species, with total herb cover ranging from 20-70%. Species often include <i>Corydalis caseana ssp. brandegeei, Heracleum maximum, Oxypolis fendleri, Mertensia ciliata, Mertensia franciscana, Maianthemum racemosum ssp. amplexicaule, Streptopus amplexifolius, Pyrola asarifolia, Cardamine cordifolia, Hydrophyllum fendleri</i>, among many others. Graminoids commonly include <i>Calamagrostis canadensis, Carex aquatilis, Glyceria striata, Elymus glaucus, Carex disperma</i>, and <i>Bromus ciliatus</i>. Bryophyte cover is often moderate. |

This association has only been documented at two sites on the western slope of the southern Rocky Mountains in Colorado. It is found associated with cold freshwater springs originating on hillsides and at the heads of small draws producing this characteristic assemblage of species. The springs can be found at all elevations within the Piceance Basin, 1370-2600 m (4500-8800 feet). Carex nebrascensis and Catabrosa aquatica are the dominant, constant species of this community, although Carex microptera, Juncus balticus, and Poa pratensis may also be important in some stands. Associated species include Hippuris vulgaris, Hordeum jubatum, Ranunculus cymbalaria, and Zannichellia palustris. |
