Comm #12301	Schizachyrium scoparium - Sorghastrum nutans - Aristida lanosa - Polypremum procumbens Herbaceous Vegetation » more details accession code: VB.CC.36769.CEGL002397	Midwestern Ecology Working Group...	0	This bluestem sand prairie is found in the United States in the Mississippi Embayment of Missouri and sand barrens in southwestern Indiana. Stands occur on nearly level to steeply sloped elevated terraces, knolls, ridges, and natural levees. The parent material is eolian or alluvial sand, associated with the Bulltown Soil Series. This tallgrass or midgrass prairie is composed of a single layer of dominant graminoids intermixed with abundant forbs. The herbaceous layer is dominated by <i>Schizachyrium scoparium</i> and <i>Sorghastrum nutans</i>. Other species can include <i>Lithospermum canescens, Cyperus</i> spp. (including <i>Cyperus grayoides</i>), <i>Polypremum procumbens, Desmodium strictum, Digitaria cognata var. cognata, Aristida</i> spp., and <i>Callirhoe triangulata</i>.
Comm #12302	Quercus velutina - Quercus coccinea - Carya texana Ozark Forest » more details accession code: VB.CC.36740.CEGL002399	Midwestern Ecology Working Group...	0	This oak - hickory forest community is found in the United States in the Ozarks of southeastern Missouri and possibly northeastern Arkansas. Stands occur on dry slopes, with thin soils and primarily a cherty bedrock near the surface. The canopy is dominated by <i>Quercus velutina, Quercus coccinea</i>, and <i>Carya texana</i>. Other associates and understory characteristics have yet to be described, but <i>Quercus alba</i> may also be present, along with minor amounts of <i>Pinus echinata</i> and shrubs such as <i>Vaccinium arboreum</i>. Sources indicate that this type primarily occurs on former <i>Pinus echinata</i> woodland sites that were completely logged, then grazed and burned, leading to a degraded oak forest.
Comm #12303	Distichlis spicata Tidal Herbaceous Alliance » more details accession code: VB.CC.22813.DISTICHLISSPICA	Southeastern Ecology Working Gro...	0	This alliance includes upper tidal areas dominated by Distichlis spicata, often mixed with other halophytic grasses and succulents such as Sporobolus virginicus, Sarcocornia perennis, Batis maritima, Lycium carolinianum, Heliotropium curassavicum, and others.

Comm #12305	(Carex interior, Carex lurida) - Carex leptalea - Parnassia grandifolia - Rhynchospora capillacea Herbaceous Vegetation » more details accession code: VB.CC.37133.CEGL002404	Midwestern Ecology Working Group...	0	This fen community type is found in the Ozarks region of the United States. Stands occur on the sideslopes of hills in narrow valleys, bases of bluffs, rock ledges, and terraces, where the soil or substrate is saturated by calcareous groundwater seepage. Soils are mucky peat or mineral, with pH above 6.5, and very shallow (0-40 cm), depending on natural disturbance and slope. The parent material is a mixture of gravel and dolomite with fragments of deeply weathered bedrock present. The bedrock strata are exposed, especially in hanging fens where the slope is greater than 35°. Hydrophytic plants dominate this mixed grass or sedge fen that is a complex of zoned vegetation. Type 1) saturated areas dominated by tussock sedges such as <i>Carex interior</i> and <i>Carex lurida</i>; Type 2) deep muck saturated areas, dominated by those sedges and by <i>Carex hystericina, Carex suberecta</i>, and the shrub <i>Alnus serrulata</i>; Type 3) marly ooze areas dominated by <i>Carex leptalea, Rhynchospora capillacea</i>, and <i>Scleria verticillata</i>; Type 4) drier areas or margins dominated by <i>Andropogon gerardii, Rudbeckia fulgida var. umbrosa</i>, and <i>Parnassia grandifolia</i>. Characteristic species include <i>Menyanthes trifoliata</i> and <i>Pogonia ophioglossoides</i>. Other species present in most examples include <i>Carex hystericina, Castilleja coccinea, Fuirena simplex, Helenium autumnale, Lobelia siphilitica, Schoenoplectus americanus (= Scirpus americanus), Scirpus atrovirens, Scirpus pendulus (= Scirpus lineatus), Selaginella apoda, Packera aurea (= Senecio aureus)</i>, and <i>Oligoneuron rigidum var. rigidum (= Solidago rigida ssp. rigida)</i>. Deep muck fens may also contain <i>Thelypteris palustris var. pubescens, Lysimachia quadriflora, Selaginella eclipes, Rudbeckia fulgida var. umbrosa, Carex granularis, Oxypolis rigidior, Physocarpus opulifolius, Pedicularis lanceolata, Cardamine bulbosa</i>, and <i>Viola cucullata</i>.

Comm #12308	Quercus stellata / Cinna arundinacea Flatwoods Forest » more details accession code: VB.CC.36718.CEGL002405	Midwestern Ecology Working Group...	0	This dry post oak flatwoods type is found in the central midwestern United States. Stands occur on both glaciated and unglaciated areas, with the majority of the range over glacial till of Illinoisan age, to the north of the Ohio River. Stands occur on level or nearly level sites. Soils contain a well-developed subsurface hardpan that is impermeable or nearly impermeable, causing a shallowly perched water table. The soil moisture fluctuates widely throughout the growing season. Depressions may form seasonal or ephemeral (vernal) ponds. The vegetation contains a dominant tree layer with an average canopy cover of 80% or more. Trees may be stunted due to the unfavorable soil conditions. The canopy is typically strongly dominated by <i>Quercus stellata</i>, but may include <i>Quercus alba, Quercus bicolor, Quercus falcata, Quercus marilandica</i>, and, more rarely, <i>Quercus palustris</i>. In Illinois, the shrub and woody vine strata may contain <i>Parthenocissus quinquefolia, Rosa carolina, Rubus allegheniensis, Rubus flagellaris</i>, and <i>Toxicodendron radicans</i>. The shrub strata may not be distinct. The herbaceous layer can be fairly disparate from one stand to the next. Some stands can be dominated by <i>Cinna arundinacea, Chasmanthium latifolium</i> and <i>Eleocharis tenuis var. verrucosa (= Eleocharis verrucosa)</i>. Plants more typical of dry and dry-mesic soil grow on slight rises, including <i>Carex festucacea, Carex pensylvanica, Danthonia spicata, Helianthus divaricatus</i>, and others. In Kentucky, this community occurs on relatively high flat areas that are no longer flooded, such as ancient Quaternary or Tertiary post-glacial meltwater lakebeds and high terraces of the Upper Gulf Coastal Plain and Shawnee Hills. In addition to the nominal species, the canopy in Kentucky may have <i>Quercus alba</i> and <i>Carya texana</i>. Herbaceous cover is sparse to moderate; leaf litter is the dominant ground cover. A fragipan layer leads to 'xerohydric' conditions. Local dominance in depressions is of wetland species (<i>Juncus</i>, etc.). Dry areas in Kentucky will have <i>Manfreda virginica, Croton willdenowii, Danthonia spicata, Porteranthus stipulatus, Pycnanthemum tenuifolium</i>, and <i>Prenanthes aspera</i> (characteristic of open areas). In Kentucky, stands grade downslope into bottomland hardwood forest and cypress swamp and upslope into mesic upland or dry oak-hickory forest.

Comm #12310	Fagus grandifolia - Acer saccharum - Liriodendron tulipifera Unglaciated Forest » more details accession code: VB.CC.36925.CEGL002411	Midwestern Ecology Working Group...	0	This beech - maple forest is found in unglaciated areas of the east-central United States. Stands occur on unglaciated terraces and mesic slopes of maturely dissected plateaus and submontane regions. The aspect is neutral on sandy alluvial terraces and is northern to eastern on slopes. Soils are moderately well-drained, moist, rich and deep (100+ cm). The vegetation is dominated by a closed-canopy forest with a well-developed tall-shrub layer. The forest canopy is dominated by <i>Fagus grandifolia</i> and <i>Acer saccharum</i>. Other canopy species include <i>Liriodendron tulipifera, Liquidambar styraciflua, Fraxinus americana, Quercus rubra, Carya glabra</i>, and <i>Carya cordiformis</i>. Shrubs commonly found in this community are <i>Asimina triloba</i> and <i>Lindera benzoin</i>. Herbaceous species are diverse, forming a dense cover. They include <i>Adiantum pedatum, Arisaema triphyllum, Asarum canadense, Carex blanda, Dicentra canadensis, Dioscorea quaternata, Galium circaezans, Menispermum canadense, Phegopteris hexagonoptera, Polystichum acrostichoides</i>, and <i>Sanguinaria canadensis</i>. The large size of dominant canopy species (over 30 m tall), herbaceous diversity, and accumulated litter emphasize the high degree of mesophytism. Community occurrences have been extensively logged, and the canopy openings favor regeneration of <i>Acer saccharum</i>. In the Appalachians of eastern Kentucky, other typical trees include <i>Aesculus flava</i> (locally abundant), <i>Juglans cinerea, Juglans nigra, Magnolia acuminata, Quercus muehlenbergii</i>, and <i>Ulmus rubra</i>.
