Comm #11531	Polygonum spp. - Echinochloa spp. - Distichlis spicata Playa Lake Herbaceous Vegetation » more details accession code: VB.CC.36790.CEGL002039	Midwestern Ecology Working Group...	0	This wetland community is found in the central Great Plains of the United States, where it occurs in shallow depressions on gently to moderately sloping topography. Soils are deep to moderately deep loams or clay loams underlain by a dense clay sublayer. Ponds often draw down periodically in these playa-type habitats. Annual herbaceous graminoids and forbs, mostly <1 m tall, dominate the exposed mud flats, and species composition and extent of the community fluctuate from site to site and year to year. In Nebraska, graminoids include <i>Cyperus acuminatus, Eleocharis engelmannii</i>, and <i>Echinochloa muricata</i>, and forbs include <i>Bacopa rotundifolia, Coreopsis tinctoria, Elatine rubella, Heteranthera limosa, Limosella aquatica, Lindernia dubia, Mollugo verticillata, Polygonum pensylvanicum (= Polygonum bicorne), Polygonum lapathifolium, Rumex stenophyllus</i>, and <i>Sagittaria calycina</i>. In Kansas, graminoids include <i>Hordeum jubatum</i>, and forbs include <i>Ambrosia grayi, Symphyotrichum subulatum (= Aster subulatus)</i>, and <i>Chenopodium berlandieri</i>. The frequent water fluctuations and thick clay pan prevent establishment of most perennial hydrophytes, such as <i>Schoenoplectus</i> spp. (= <i>Scirpus</i> spp.) and <i>Typha</i> spp.

Comm #11535	Distichlis spicata - Schoenoplectus maritimus - Salicornia rubra Herbaceous Vegetation » more details accession code: VB.CC.37081.CEGL002043	Midwestern Ecology Working Group...	0	This community is found in the southeastern Great Plains of the United States, in basins or floodplains. It is dependent on periodic influx of saline water to maintain the characteristic soil and water chemistry. The soils of this community are deep and poorly drained and the parent material is alluvium or loess. This community is flooded or saturated for most of the year. It may dry out in late summer and fall. Herbaceous plants dominate, and trees and other woody plants are almost completely absent. The dominant species are <i>Distichlis spicata, Salicornia rubra</i>, and <i>Schoenoplectus maritimus (= Scirpus maritimus)</i>. <i>Symphyotrichum subulatum (= Aster subulatus), Hordeum jubatum, Iva annua, Sporobolus texanus</i>, and <i>Suaeda calceoliformis</i> are all common. Few individuals in this community exceed 1 m and most are less than 0.5 m. There can be unvegetated ground, especially in the wettest and most saline parts of this community. <i>Ruppia maritima</i> and <i>Stuckenia pectinata (= Potamogeton pectinatus)</i> may persist in pools in the wettest areas. The vegetation is more dense with few stretches of bare ground on the drier and less saline parts.
Comm #11536	Potamogeton spp. - Ceratophyllum demersum Great Plains Herbaceous Vegetation » more details accession code: VB.CC.36906.CEGL002044	Midwestern Ecology Working Group...	0	This community type is found in the Great Plains of the United States in shallow to relatively deep (1 m) freshwater basins or bands in marshes or bays that remain flooded in all but the driest years. Vegetation varies from sparse to dense, with submersed rooted and free-floating macrophytes. Species composition varies with substrate, water depth, water chemistry, turbidity, water temperatures and other factors, but these are poorly understood. Dominant species in Nebraska include narrow-leaved pondweeds (<i>Potamogeton foliosus, Stuckenia pectinata (= Potamogeton pectinatus), Potamogeton pusillus), Najas guadalupensis</i>, and <i>Zannichellia palustris</i>. <i>Ceratophyllum demersum</i> and <i>Utricularia macrorhiza</i> can be locally abundant. In quiet bays, <i>Potamogeton nodosus</i> and <i>Lemna</i> spp. are common. In clear water with sandy bottoms <i>Chara</i> spp. may also be common.

Comm #11539	Riverine Sand Flats - Bars Sparse Vegetation » more details accession code: VB.CC.36731.CEGL002049	Midwestern Ecology Working Group...	0	This community ranges from the western Great Plains to the eastern parts of the midwestern United States and Canada. It is a sparsely vegetated community that occurs along river shorelines, islands, pointbars, and flats. These sandbars form when receding floodwaters deposit sand and lesser amounts of clay, silt, and cobbles in the stream bed. Soils are often undeveloped due to the ephemeral nature of the stands. Drainage depends on depth above the water level. Herbaceous species shared in Missouri and Nebraska include <i>Cyperus</i> spp. (<i>Cyperus erythrorhizos, Cyperus odoratus, Cyperus squarrosus), Eragrostis hypnoides, Eragrostis trichodes, Leptochloa fusca ssp. fascicularis (= Leptochloa fascicularis), Polygonum</i> spp. (including <i>Polygonum lapathifolium), Rorippa sinuata, Sporobolus cryptandrus</i>, and <i>Xanthium strumarium</i>.
Comm #11540	Pinus remota - Juniperus ashei - Quercus spp. Woodland » more details accession code: VB.CC.36035.CEGL002124	Southeastern Ecology Working Gro...	0	This community occurs in the Edwards Plateau of central Texas. The open canopy consists of <i>Pinus remota, Juniperus ashei, Quercus fusiformis</i>, and <i>Quercus vaseyana (= Quercus pungens var. vaseyana)</i>. The shrub layer may contain <i>Acacia berlandieri, Acacia roemeriana, Mahonia trifoliolata (= Berberis trifoliolata), Condalia viridis, Diospyros texana, Forestiera reticulata, Jatropha dioica, Rhus virens, Salvia ballotiflora</i>, and <i>Sophora secundiflora</i>. Graminoids include <i>Bouteloua curtipendula, Carex planostachys, Dichanthelium pedicellatum, Erioneuron pilosum, Poa bigelovii</i>, and <i>Vulpia octoflora</i>.
