Comm #411	Pinus taeda - Quercus (falcata, nigra) / Morella cerifera / Vitis rotundifolia Forest » more details accession code: urn:lsid:vegbank.org:commConcept:34690-{E409C4E1-5021-4CEE-9FB5-D3BDD569CE1A}	NatureServe Biotics 2019	46	This mid-Atlantic coastal upland loblolly pine forest occurs on the Outer Coastal Plain and on barrier islands in sheltered backdunes protected from salt spray and overwash. The substrate is rapidly drained, nutrient-poor sands or sandy loams. This community is dominated by <i>Pinus taeda</i>, which can be the sole canopy component or can be associated with <i>Quercus falcata, Prunus serotina var. serotina, Quercus nigra</i>, and <i>Sassafras albidum</i>. The tall-shrub layer, when present, is composed of <i>Morella cerifera</i> and <i>Vaccinium corymbosum</i>. Vines and lianas are nearly always present in abundance; <i>Vitis rotundifolia</i> is most common, but <i>Toxicodendron radicans, Smilax rotundifolia, Smilax glauca</i>, and <i>Parthenocissus quinquefolia</i> are often present in abundance as well. The herbaceous layer is typically sparse, particularly if shrubs and vines are dense, but <i>Chasmanthium laxum</i> may be fairly abundant in this community. Other herbs include <i>Panicum amarum var. amarulum, Eupatorium hyssopifolium</i>, and <i>Elephantopus nudatus</i>. In southern Virginia, <i>Quercus virginiana</i> and <i>Gelsemium sempervirens</i> may also be present, but <i>Quercus virginiana</i> is never abundant and when present is usually restricted to the understory. In the Chesapeake Marshlands, small patches of this community were observed on Smith Island and north of Bishops Head Point near the Chesapeake Bay Foundation lodge. Vegetation at Bishops Head occupied a small upland hummock which was presumably an old homesite and therefore very fragmented.
Comm #412	Alnus serrulata Appalachian Seepage Shrubland » more details accession code: urn:lsid:vegbank.org:commConcept:35378-{7AA089CD-CECE-4064-BCD0-E6E6DC022459}	NatureServe Biotics 2019	46	This type represents saturated vegetation dominated by <i>Alnus serrulata</i> from the Appalachian ecoregion of the southeastern United States. Stands are dominated by <i>Alnus serrulata</i>. In West Virginia, additional shrubs with less cover include <i>Cornus amomum, Rosa palustris, Ilex verticillata</i>, and <i>Spiraea alba</i>. There is usually high cover in the herb layer dominated by wetland indicators, including <i>Leersia oryzoides, Boehmeria cylindrica, Onoclea sensibilis, Scutellaria lateriflora, Glyceria striata, Polygonum sagittatum, Chelone glabra, Cinna arundinacea, Galium tinctorium, Impatiens capensis, Symplocarpus foetidus, Carex stricta, Carex gynandra, Osmunda regalis, Sagittaria latifolia</i>, and <i>Scirpus cyperinus</i>.

Comm #416	Adenostoma fasciculatum - Ceanothus crassifolius - Malosma laurina Shrubland » more details accession code: VB.CC.37406.CEGL003517		45	This shrubland association occurs on somewhat steep to steep slopes of variable aspect at low to mid elevations between 17 and 821 m. It is dominated by both <i>Adenostoma fasciculatum</i> and <i>Ceanothus crassifolius</i> in the shrub layer, although <i>Ceanothus crassifolius</i> has typically somewhat higher cover. The herbaceous layer is sparse except for occasional vines of <i>Marah macrocarpus</i>, which may sprawl over the shrubs. Trees are generally absent.

Comm #419	Populus angustifolia / Cornus sericea Riparian Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:31572-{721C7C28-7603-4913-AAA1-920699C00EE5}	NatureServe Biotics 2019	45	This narrowleaf cottonwood forest type is found in the western Great Plains and western mountain regions of the United States, north into Alberta, Canada. Elevations range from 2360 to 2720 m (7750-8900 feet) in northern New Mexico to 945 to 2044 m (3100-6700 feet) in Montana (east of the Continental Divide). Stands occur along major streams and small to moderate-sized rivers in the foothill-montane zone and northern plains and in the grassland zone of Alberta. Sites include narrow valleys (10 m) with swift, steep streams (4% gradient) where it occurs on narrow benches, and on wide valleys (150 m) on broad floodplains along, moderately steep, meandering rivers (2% gradients). Soils are highly variable and stratified. The vegetation is characterized by a closed to open canopy of deciduous trees dominated by <i>Populus angustifolia</i> and a thick understory of <i>Cornus sericea</i>. The tree canopy composition is highly variable but typically has less than 10% cover of other tree species, including conifers <i>Picea pungens, Pseudotsuga menziesii, Pinus ponderosa, Abies concolor, Abies lasiocarpa</i>, and deciduous trees such as <i>Populus tremuloides</i> in mountains and <i>Populus deltoides</i> in lower foothills and on plains. <i>Populus x acuminata</i> may codominate stands in the Great Basin and in Alberta. In northern plains, stands may have <i>Populus deltoides</i> and/or <i>Populus balsamifera ssp. trichocarpa</i> present. The introduced tree <i>Elaeagnus angustifolia</i> may be common on disturbed stands. The moderately dense to dense shrub layer consists mostly of <i>Cornus sericea</i> (10-80%) but may be diverse. Other shrub species can be abundant, but rarely more than <i>Cornus sericea</i>, and may include <i>Acer glabrum, Alnus incana, Amelanchier</i> spp., <i>Crataegus rivularis, Betula occidentalis, Lonicera involucrata, Prunus virginiana, Quercus gambelii, Ribes</i> spp., <i>Rosa woodsii, Rubus</i> spp., many species of <i>Salix</i>, and <i>Symphoricarpos</i> spp. The herbaceous cover can be abundant (&gt;50% cover) and diverse. Forb species may include <i>Equisetum arvense, Heracleum maximum, Maianthemum stellatum, Rudbeckia laciniata, Osmorhiza</i> spp., <i>Solidago canadensis</i>, and <i>Symphyotrichum foliaceum</i>. Graminoid cover can also be abundant and includes <i>Bromus anomalus, Carex pellita, Elymus glaucus, Glyceria striata</i>, and <i>Phalaris arundinacea</i>. Introduced species, such as <i>Agrostis gigantea, Agrostis stolonifera, Alopecurus pratensis, Bromus inermis, Cirsium arvense, Dactylis glomerata, Medicago sativa, Phleum pratense, Poa compressa, Poa palustris</i>, and <i>Poa pratensis</i>, are often abundant.
Comm #420	Quercus montana - Pinus virginiana - (Pinus pungens) / Schizachyrium scoparium - Dichanthelium depauperatum Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:36596-{9B589FC9-B604-44AE-8DAF-A62059BEF147}	NatureServe Biotics 2019	45	This community is a mixed oak-pine woodland with a canopy of stunted, often gnarled trees, varying from semi-open to very open. It occurs on steep convex slopes, ridge spurs, and clifftops which have high solar exposure. Most are on moderate to steep slopes with much exposed mineral soil. Sites are confined to lower elevations (&lt;770 m [2500 feet]), are distinctly xeric, and usually have southeast to southwest aspects. Underlying bedrock includes quartzite, metasandstone and sandstone, granite, shale, and other acidic rocks. Surface cover of outcrops and loose stones is relatively high. Soils are extremely acidic. The canopy is typically codominated by <i>Quercus montana</i> and <i>Pinus virginiana</i> in variable proportions; in some slightly more mesic occurrences, <i>Quercus rubra</i> may occur with or in place of <i>Quercus montana</i>. <i>Pinus pungens</i> is an important, even dominant, associate in a minority of stands. Minor but relatively constant tree associates include <i>Carya glabra, Amelanchier arborea</i>, and <i>Sassafras albidum</i>. Minor, inconstant tree associates include <i>Quercus coccinea, Quercus velutina, Quercus stellata, Quercus marilandica, Quercus alba, Carya tomentosa, Carya ovata, Juniperus virginiana, Pinus strobus</i>, and <i>Fraxinus americana</i>. The shrub layer varies from moderately dense to sparse, with <i>Vaccinium pallidum</i> and <i>Vaccinium stamineum</i> the most constant and abundant species. <i>Quercus ilicifolia, Kalmia latifolia, Rhus copallinum, Rhus aromatica, Rosa carolina, Castanea pumila, Viburnum acerifolium</i>, and <i>Toxicodendron pubescens</i> are inconstant, but occasionally common, in the type. Herbaceous composition and density vary with shrub density. Graminoid-rich openings dominated by <i>Schizachyrium scoparium, Dichanthelium depauperatum, Carex pensylvanica, Danthonia spicata</i>, and <i>Dichanthelium commutatum</i> are frequent. Also present is a surprising variety of low-cover forbs, among the most characteristic of which are <i>Hieracium venosum, Solidago erecta, Potentilla canadensis, Campanula divaricata, Viola sagittata, Houstonia longifolia, Antennaria plantaginifolia, Aureolaria laevigata, Helianthus divaricatus, Cunila origanoides, Symphyotrichum undulatum, Coreopsis verticillata, Tephrosia virginiana, Lespedeza frutescens, Polygonatum biflorum var. biflorum, Taenidia integerrima, Asplenium platyneuron</i>, and <i>Clitoria mariana</i>.
