Elaeagnus commutata Shrubland

This shrubland is a minor type forming narrow stringers on stream terraces and at the margins of riparian areas. Elevation ranges from about 610 m on the Great Plains to 1524 m (2000-5000 feet) along the front of the Rocky Mountains. Soils are silty and derived from alluvium. Surficial geology is glacial-fluvial or lacustrine-fluvial deposits. Litter and duff cover 70% of the ground. Stands in the foothills of the Rocky Mountains appear to be more mesic than those from the eastern plains. Consequently, the species composition is variable. Stands located closer to the mountains and larger riparian areas have more mesic species. Stands surrounded by plains or foothill grasslands tend to have more typical dry-mesic species. <i>Elaeagnus commutata</i> is the dominant shrub throughout. <i>Salix</i> spp., <i>Amelanchier alnifolia, Prunus virginiana, Rosa woodsii</i>, and <i>Artemisia cana</i> may also be present. Common introduced graminoid species include <i>Poa pratensis, Phleum pratense</i>, and <i>Agrostis gigantea (= Agrostis alba)</i>. Native abundant grasses include <i>Elymus lanceolatus (= Agropyron dasystachyum), Koeleria macrantha, Calamagrostis canadensis, Festuca campestris</i>, and <i>Hesperostipa comata (= Stipa comata)</i>. Forb cover can be variable and may include <i>Galium boreale, Ranunculus acriformis, Senecio triangularis, Pulsatilla patens ssp. multifida (= Anemone patens)</i>, and <i>Geum triflorum</i>. |

The shagbark hickory / prickly ash alvar woodland type is only known from the Flamborough Plains in southern Ontario west of Lake Ontario, where it is found on shallow soils over flat dolostone outcrops (pavements). Other examples may exist in the Lake Erie and Lake Ontario watersheds. This savanna community has scattered trees forming 10-25% canopy cover, and a variable understory with shrubby patches and grassy patches. The dominant tree is Carya ovata; other characteristic trees include Quercus macrocarpa, Quercus muehlenbergii, Fraxinus americana, and Ulmus thomasii. The most abundant shrub is Zanthoxylum americanum; other characteristic shrubs are Cornus racemosa (= Cornus foemina ssp. racemosa), Rhamnus cathartica, Prunus virginiana, and Symphoricarpos albus). Characteristic herbs of grassy patches in the ground layer are Danthonia spicata, Hieracium piloselloides, Panicum philadelphicum, Carex pensylvanica, Poa compressa, and Solidago nemoralis. Small outcrops of dolostone pavement are common; characteristic herbs on pavement patches include Isanthus brachiatus (= Trichostema brachiatum), Geranium bicknellii, and Panicum spp. |

This witch-hazel - dogwood gravel wash occurs in the Ozarks-Ouachita region of the United States. This shrubland occurs as narrow strips (1-10 m wide) in the upper scour zones of small to medium-sized streams. It is typically found in a substrate of loose cobble, but on larger streams and rivers may occur on bedrock shelves or alluvial silt, where it intergrades with other vegetation types. <i>Hamamelis vernalis, Cornus obliqua (= Cornus amomum ssp. obliqua)</i>, and <i>Hypericum prolificum</i> are common and characteristic. Several other species may be locally abundant in the diverse microhabitats of this shrubland, including <i>Salix caroliniana</i> in more open streambeds, <i>Leptopus phyllanthoides (= Andrachne phyllanthoides)</i> in drier scour zones, <i>Juniperus virginiana var. virginiana</i> in upper scour zones, <i>Ilex vomitoria</i> on bedrock and boulders on larger streams, and <i>Alnus serrulata</i> and <i>Cephalanthus occidentalis</i> in low, wet areas. On more stable substrates <i>Platanus occidentalis, Acer rubrum</i>, and <i>Liquidambar styraciflua</i> may be locally abundant. Other shrub and tree species that may occur include <i>Amorpha fruticosa, Amorpha ouachitensis, Betula nigra, Crataegus</i> spp., <i>Diospyros virginiana, Ulmus alata, Hypericum prolificum, Ilex decidua, Styrax grandifolius</i>, and <i>Vaccinium virgatum</i>. Herbaceous species include <i>Amsonia illustris, Amsonia hubrichtii, Ambrosia</i> spp., <i>Apios americana, Boltonia diffusa, Chasmanthium latifolium, Commelina erecta, Diodia virginiana, Eupatorium fistulosum, Ludwigia decurrens, Polygonum pensylvanicum, Vernonia lettermannii, Panicum virgatum, Panicum anceps</i>, and <i>Perilla frutescens</i> (exotic). <i>Trachelospermum difforme</i> is a common vine of this community. |

This alliance includes high-elevation, herb-dominated seepage slopes of the southern Blue Ridge. This alliance is currently defined for North Carolina and Tennessee but may extend into Virginia. Associations in this alliance are perennial wetlands on pronounced slopes at elevations over 5000 feet. The vegetation is graminoid-dominated and has coverage by Sphagnum sp. These seeps are open, although trees and shrubs can be present, particularly around the seep margins. Associations in this alliance are surrounded by, or were formerly surrounded by, forests dominated by Abies fraseri and Picea rubens or by the highest northern hardwood forests (forests dominated by Fagus grandifolia, Betula alleghaniensis, and Aesculus flava). They are influenced by the high rainfall and low evaporation rates in these high mountain landscapes. |

This alliance consists of tropical wet prairies dominated by Rhynchospora microcarpa. It has been reported from the Big Cypress area. This alliance is poorly defined and needs additional assessment and comparison to other vegetation types to confirm its distinctiveness. |

This putative vegetation type has been described from the western side of the Bighorn Mountains of north-central Wyoming, where it is found along stream channels (often dry) and around springs, in limestone canyons. The vegetation usually consists of patches of shrubs, up to 1 m tall, scattered in a dense herbaceous undergrowth. Composition of the vegetation varies from stand to stand, but <i>Ribes lacustre</i> dominates or codominates a medium-height shrub layer that often includes <i>Ribes oxyacanthoides, Rosa woodsii</i>, and <i>Rubus idaeus</i>. <i>Mertensia ciliata</i> contributes as much cover to the undergrowth as does any other species, and <i>Poa pratensis, Achillea millefolium, Actaea rubra, Taraxacum</i> spp., and <i>Fragaria virginiana</i> often are present and may contribute substantial cover. <i>Pseudotsuga menziesii var. glauca</i> forms an open tree overstory in some stands, and <i>Acer glabrum, Cornus sericea</i>, or <i>Salix bebbiana</i> may form a sparse tall-shrub layer. |
