Comm #1731	Planera aquatica Floodplain Forest » more details accession code: urn:lsid:vegbank.org:commConcept:35639-{43A28773-4FE5-469A-AFBB-EC5597C6BAE1}	NatureServe Biotics 2019	8	This association consists of forests of the southeastern United States Coastal Plain in which <i>Planera aquatica</i> is dominant and may form an essentially monospecific canopy. Relatively few additional species are present in other vegetational strata, although these short-statured forests sometimes have a scattered emergent canopy of other tree species typical of flooded swamps. The herbaceous and vine/liana strata are sparse, and no species are known to be diagnostic of this type relative to other bottomlands. Due in part to extreme periods of inundation, this habitat is typically very low in species diversity.
Comm #1732	Quercus texana - Quercus lyrata Floodplain Forest » more details accession code: urn:lsid:vegbank.org:commConcept:35648-{3F7C4762-B972-4946-BF8C-7F9E60D359A0}	NatureServe Biotics 2019	8	This bottomland forest occurs in the floodplain of rivers and possibly large streams in parts of the West Gulf Coastal Plain and in the Mobile-Tensaw Delta and the Mississippi River Alluvial Plain. Canopy dominants are <i>Quercus lyrata, Quercus texana, Quercus nigra, Liquidambar styraciflua, Celtis laevigata var. laevigata, Ulmus americana, Fraxinus pennsylvanica</i>, and <i>Carya aquatica</i>. Depressions within the community may contain <i>Taxodium distichum</i> and <i>Nyssa aquatica</i>. Understory and shrub strata are sparse and include <i>Diospyros virginiana, Carpinus caroliniana, Ilex decidua</i>, and <i>Acer rubrum</i>. Common woody vines include <i>Bignonia capreolata, Parthenocissus quinquefolia, Berchemia scandens, Toxicodendron radicans, Vitis rotundifolia</i>, and <i>Campsis radicans</i>. Ground cover is very sparse; species include <i>Carex</i> spp., <i>Saururus cernuus, Boehmeria cylindrica, Chasmanthium</i> sp., <i>Mitchella repens</i>, and <i>Polygonum</i> spp. Soils are organic dark brown silt loams including Perry clay. Duration of flooding is relatively long with lower spots being permanently saturated. Mature examples of this community have sparse shrub strata and a very sparse herbaceous layer.
Comm #1733	Nyssa biflora / Itea virginica - Cephalanthus occidentalis Swamp Forest » more details accession code: urn:lsid:vegbank.org:commConcept:35665-{BF3B703D-192F-4C07-86BC-B7ED2A189036}	NatureServe Biotics 2019	8	This community occupies peaty or mucky, acidic, semipermanently wet depressions in the Atlantic and East Gulf coastal plains. This community is strongly dominated by <i>Nyssa biflora</i>. Other bottomland species, including <i>Taxodium distichum</i> and <i>Taxodium ascendens</i>, may also be present, but combined usually contribute less than 30% of the canopy. Shrubs are scarce to scattered on hummocks and become more common with peat accumulation. Shrub species include <i>Itea virginica</i> and <i>Cephalanthus occidentalis</i>, with <i>Clethra alnifolia, Lyonia lucida, Cliftonia monophylla</i>, and <i>Cyrilla racemiflora</i> being common in the East Gulf and Atlantic coastal plains. Floating logs and stumps provide habitat for the sparse herbaceous stratum. Species include <i>Woodwardia virginica, Woodwardia areolata, Osmunda cinnamomea, Eriocaulon</i> spp., <i>Xyris</i> spp., <i>Rhynchospora</i> spp., <i>Schoenoplectus</i> spp., and <i>Juncus</i> spp. The moderately to strongly acidic sandy soils are overlain by organic muck and leaf litter. This community occurs in depressions on the Coastal Plain of Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, and Mississippi; and sparingly on the Piedmont of South Carolina, Georgia, and Alabama.
Comm #1734	Pinus taeda - Quercus alba - (Fagus grandifolia) / Smilax pumila - Mitchella repens Forest » more details accession code: urn:lsid:vegbank.org:commConcept:35725-{35722E1E-701A-4AC2-BF4A-08E94F455312}	NatureServe Biotics 2019	8	This acidic, mesic mixed forest of the West Gulf Coastal Plain may best be described as hardwood - loblolly forest. Taken together, hardwoods are more abundant and important than are pines, however, <i>Pinus taeda</i> may be the single most dominant species in the overstory with individual trees attaining large diameters and height. The core concept of this type are stands with a significant component of mesic site species in all strata, although somewhat slightly drier forms may be included as long as <i>Quercus alba</i> is important in the overstory. This type occurs in a variety of ecological settings in the region, including middle and lower slopes between uplands and stream bottoms and at the heads of drainages along small, intermittent streams on acidic sandy loams, silt loams and silty clays, and mesic situations in flatwoods environments.
Comm #1735	Pinus serotina / Gordonia lasianthus - Persea palustris Swamp Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:36163-{A7BF12D7-0619-43CE-B121-F119C5A4C22E}	NatureServe Biotics 2019	8	These evergreen forest/woodlands occur within creek drainages, depressions, and in ecotonal seepage areas between fire-maintained longleaf pine uplands and adjacent creeks and/or lakes. Most known examples are documented from Camp Blanding Military Reservation in northeastern Florida, but this community is also known from Ocala National Forest and Timucuan Ecological and Historic Preserve. A canopy of <i>Pinus serotina</i> (typically of 50% cover or less) overtops a subcanopy of <i>Persea palustris, Gordonia lasianthus</i>, and <i>Magnolia virginiana</i>. Occasionally <i>Pinus elliottii</i> may occur in the canopy with <i>Pinus serotina</i>. The community is typically dense with midstory and understory shrubs, which include <i>Persea palustris, Gordonia lasianthus, Cyrilla racemiflora, Ilex coriacea, Viburnum nudum, Lyonia lucida, Morella</i> spp., and occasional <i>Agarista populifolia</i>. The ferns <i>Osmunda cinnamomea</i> and <i>Woodwardia areolata</i> are sometimes present, and the vine <i>Smilax laurifolia</i> is usually found in small amounts. In northeastern Florida, at the Timucuan Ecological and Historic Preserve, dead and dying <i>Persea palustris</i> indicate that this community is being affected by laurel wilt, which is caused by a vascular wilt fungus that is transmitted to species in the Lauraceae family via. the non-native redbay ambrosia beetle (<i>Xyleborus glabratus</i>).
Comm #1736	Carex gynandra - Scirpus cyperinus - Eriophorum virginicum - Osmunda cinnamomea Herbaceous Seep » more details accession code: urn:lsid:vegbank.org:commConcept:35958-{2CE22989-0172-47EE-860C-9DF06AF20733}	NatureServe Biotics 2019	8	This association consists of patches of saturated vegetation located in areas of flat to very gently sloping topography (0-2°) located near streams in the Allegheny and Cumberland mountains. This community occurs along streams, in flats away from the immediate streambed, along wetland margins, and in seepage-fed oxbow fens, at elevations of 610 to 1220 m (2000-4000 feet). It is primarily an herbaceous community, but some examples may exhibit a shrub zone. The primary herbaceous species are <i>Carex gynandra, Carex atlantica, Juncus effusus, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Doellingeria umbellata, Polygonum sagittatum, Eriophorum virginicum, Lygodium palmatum, Platanthera clavellata, Platanthera flava var. flava, Lycopus virginicus, Oxypolis rigidior, Chelone glabra, Carex lurida, Glyceria melicaria, Scirpus cyperinus, Carex leptalea ssp. harperi, Solidago rugosa, Galium tinctorium, Solidago uliginosa, Carex scoparia var. scoparia, Dryopteris cristata, Impatiens capensis, Carex stipata, Hypericum mutilum</i>, and <i>Glyceria laxa</i>. <i>Sphagnum</i> spp. are common and include <i>Sphagnum palustre</i>. Shrubs can occur as scattered clumps or zones and include <i>Viburnum nudum var. cassinoides, Hypericum densiflorum, Salix sericea, Ilex opaca, Kalmia latifolia, Rhododendron maximum</i>, and <i>Aronia arbutifolia</i>.
Comm #1737	Quercus shumardii - Quercus muehlenbergii - Acer (floridanum, saccharum) / Ostrya virginiana Forest » more details accession code: urn:lsid:vegbank.org:commConcept:36507-{9A052643-9B60-4842-A17D-B41924722893}	NatureServe Biotics 2019	8	This deciduous forest association accommodates mesic forests dominated by <i>Quercus shumardii</i> and <i>Quercus muehlenbergii</i>, with one of several related <i>Acer</i> spp. (e.g., sugar maples - <i>Acer floridanum, Acer leucoderme, Acer saccharum</i>), depending on where the stand is located. The canopy composition varies considerably with geography. This forest occurs on soils derived from limestones, dolomites or other basic substrates, on sloping to steeply sloping topography on middle to lower slopes. In addition to the nominal species, the canopy may also contain various <i>Carya</i> spp. (including <i>Carya tomentosa, Carya glabra, Carya ovalis, Carya ovata</i>, and/or <i>Carya carolinae-septentrionalis</i>) and other basophilic and/or mesic hardwood species, including <i>Fraxinus americana, Fraxinus quadrangulata</i> (within its range), <i>Diospyros virginiana</i>, and <i>Ulmus</i> spp. (including <i>Ulmus alata, Ulmus americana, Ulmus rubra</i>, and/or <i>Ulmus serotina</i>). Other oaks, including <i>Quercus alba, Quercus rubra</i>, and <i>Quercus velutina</i>, may be present, but will not dominate the canopy. <i>Liriodendron tulipifera</i> and/or <i>Liquidambar styraciflua</i> may be present, perhaps grading in from adjoining mixed mesic forests. Subcanopy species include <i>Ostrya virginiana</i>, the <i>Acer</i> spp. mentioned above, <i>Aesculus</i> spp., <i>Cornus florida, Ulmus</i> spp., <i>Cercis canadensis, Celtis laevigata, Fraxinus quadrangulata</i>, and <i>Prunus</i> spp. Shrubs and woody vines, which vary considerably with geography and site moisture conditions, may include <i>Asimina triloba, Berchemia scandens, Calycanthus floridus, Crataegus</i> spp., <i>Euonymus americanus, Euonymus atropurpureus, Forestiera ligustrina, Frangula caroliniana, Lindera benzoin, Rhododendron canescens, Sideroxylon lycioides, Staphylea trifolia, Symphoricarpos orbiculatus</i>, and <i>Viburnum rufidulum</i>. Other common woody vines include <i>Bignonia capreolata, Lonicera sempervirens, Parthenocissus quinquefolia</i>, and <i>Toxicodendron radicans</i>. Herbs are a mixture of mesic and submesic limestone species, which also vary widely with geography. The range of this association includes the Interior Low Plateau of Kentucky and Tennessee, the Cumberlands of Alabama, and the Ridge and Valley of Georgia.
Comm #1738	Cercocarpus ledifolius / Symphoricarpos rotundifolius Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:36683-{C250A6C7-D92F-4D72-9A3D-3740448CE31D}	NatureServe Biotics 2019	8	This woodland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this association are found between 2315 and 2835 m (7600-9300 feet) of elevation on northwest to southwest aspects. Stands usually occur on midslopes though some occur on upper slopes and ridges. Slopes are moderate to steep, and soils are silty to sandy loams derived from igneous or metamorphic parent material. This association forms an intermittent canopy of <i>Cercocarpus ledifolius</i> 2-5 m in height. Occasional emergent individuals of <i>Juniperus occidentalis</i> may be present. <i>Artemisia tridentata</i> dominates the shrub layer. <i>Symphoricarpos rotundifolius</i> is the diagnostic shrub. <i>Eriogonum umbellatum, Holodiscus discolor, Chrysothamnus viscidiflorus</i>, and <i>Linanthus pungens</i> may also be present. The herbaceous layer is quite sparse and dominated by graminoids. <i>Melica stricta, Elymus elymoides</i>, and/or <i>Achnatherum hymenoides</i> are usually present. A wide diversity of other graminoids and forbs may be present at very low cover values.

Shrubs are generally &lt;3.5 m in height, and their canopy is intermittent to continuous. The herbaceous layer is sparse to grassy. This western shrubland alliance occurs from Oregon south into Baja California, Mexico. Stands are found in the Cascade, Coast, Transverse and Peninsular ranges, Klamath Mountains, and Sierra Nevada. It occupies mostly dry alluvial fans, slopes, and ridges and occurs in various elevational zones throughout its range, generally on shallow, well-drained, gravelly soils, including nutrient-deficient serpentine soils.
Comm #1740	Pinus ponderosa / Pascopyrum smithii Open Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:29097-{F2E1D699-BB85-4CD6-ACBC-4CAC53379035}	NatureServe Biotics 2019	8	This ponderosa pine woodland type is found in the northwestern Great Plains and Black Hills foothills of the United States. At Wind Cave National Park in the Black Hills of South Dakota, stands are best developed on gentle to moderately steep slopes of all aspects except south. On northerly aspects, and in stands with greater tree cover, the more mesophytic graminoids have greater cover. Drier sites may contain a more xerophytic mix of species. At Wind Cave National Park, stands are characterized by a somewhat-open canopy of <i>Pinus ponderosa</i>, with coverage in the 25-50% range. A subcanopy of smaller pines may be present. The shrub stratum is usually sparse, with <i>Amorpha canescens, Artemisia frigida, Rhus trilobata</i>, and <i>Toxicodendron pubescens</i> the most frequently found species. Herbaceous cover is typically greater than 75% and graminoid-dominated. Species composition is quite variable. On northerly aspects and in stands with greater tree cover, the more mesophytic graminoids have greater cover, such as <i>Hesperostipa spartea, Nassella viridula, Elymus canadensis, Muhlenbergia racemosa, Pascopyrum smithii</i>, and <i>Sporobolus heterolepis</i>. <i>Schizachyrium scoparium, Carex inops ssp. heliophila</i> and <i>Hesperostipa comata</i> are the common dominants on drier sites. <i>Piptatheropsis micrantha</i> is dominant at some sites.
