Comm #6901	Sideroxylon foetidissimum - Sideroxylon salicifolium - Ficus aurea - Quercus virginiana - Celtis laevigata Forest » more details accession code: VB.CC.36541.CEGL007004	Hilsenbeck, C. E., R. H. Hofstet...	0	This hardwood hammock community occurs on Indian middens in southern Florida. These forests are closely related to other hardwood hammocks of the region but may be differentiated most easily by their occurrence on anthropogenic midden piles. Because these middens are topographically higher than the immediately surrounding landscape, they apparently lack a true hydroperiod and consequently develop larger trees than some other hammocks. Many of the nominal species may also be encountered in inland hammocks of the region. Perhaps the most distinctive vegetation feature of these stands is the persistence of species cultivated by the aboriginal inhabitants.
Comm #6902	Prosopis velutina / Atriplex canescens / Mixed Grasses Shrubland » more details accession code: VB.CC.31758.CEGL005344 NOT CURRENTLY ACCEPTED	Western Ecology Working Group of...	0	This shrubland is described from Buenos Aires National Wildlife Refuge in southern Arizona. Plot data indicate elevations of 990-1180 m (3245-3550 feet) where it is found on ridgetops, alluvial fans and valley floors (including floodplains). Sites are flat to gently sloping, and soils are sandy loam to silt loam. The vegetation is characterized by an open to moderately dense (10-40% cover) tall-shrub canopy that is dominated by <i>Prosopis velutina</i> with an open to moderately dense (10-50% cover) short-shrub layer dominated by abundant <i>Atriplex canescens</i>, which is diagnostic of this association. Sometimes there is sparse to moderate cover of <i>Acacia greggii, Gutierrezia sarothrae</i>, or <i>Lycium</i> spp in the short-shrub layer. The moderately dense to dense herbaceous layer is dominated by mixed grasses but may have high species richness of forbs (>25 species), generally with relatively low cover. Characteristic species include <i>Aristida ternipes, Bouteloua aristidoides, Bouteloua barbata, Bouteloua chondrosioides, Bouteloua eriopoda, Chamaesyce florida, Evolvulus alsinoides, Ipomoea hederacea, Setaria</i> spp., and <i>Talinum aurantiacum</i>. If present, <i>Eragrostis lehmanniana</i> cover is relatively low (less than 25% cover and generally less than a third of the total perennial graminoid cover).

Comm #6904	Prosopis velutina / Mixed Grasses Shrubland » more details accession code: VB.CC.31755.CEGL005348 NOT CURRENTLY ACCEPTED	Western Ecology Working Group of...	0	This shrubland is described from the foothills of Buenos Aires National Wildlife Refuge in southern Arizona. Plot data indicate an elevational range of 915-1130 m (3000-3700 feet) where it is found on valley floors, swales and ridges. Sites are flat or gentle midslopes on all aspects. Substrates are typically well-drained sandy loam but include silt loam and clayey soils. Bare ground or small rocks frequently dominate the ground cover. The vegetation is characterized by an open to moderately dense (10-50% cover) herbaceous layer with an open (10-25% cover) tall-shrub canopy dominated by <i>Prosopis velutina</i> (10-20% cover). Mixed short shrubs are often present but are generally not dense enough to form a stratum. Associated tall and short shrubs may include <i>Acacia greggii, Gutierrezia sarothrae, Isocoma tenuisecta, Lycium</i> spp., and <i>Opuntia versicolor</i>. The herbaceous layer is composed of mixed native grasses and forbs. Common species include <i>Abutilon incanum, Aristida ternipes, Bouteloua chondrosioides, Bouteloua curtipendula, Bouteloua repens, Bouteloua rothrockii, Croton pottsii, Digitaria californica, Gutierrezia microcephala, Kallstroemia grandiflora, Muhlenbergia porteri, Portulaca oleracea (= Portulaca retusa)</i>, and <i>Talinum aurantiacum</i>. Forbs often have high species richness but with typically relatively low cover. If present, <i>Eragrostis lehmanniana</i> has low cover (less than 25% cover and less than a third of the total perennial graminoid cover).

Internatio...	0	This coconut palm woodland is currently sampled from three national historical parks in Hawaii, and this description is based on occurrences there. Additional global information will be added as it becomes available. These woodlands are found on gently sloping to flat sites on recent lava or beach. This woodland community has an open tree canopy dominated by <i>Cocos nucifera</i>. <i>Thespesia populnea, Pandanus tectorius, Prosopis pallida</i>, and <i>Tournefortia argentea</i> may be present in the canopy and/or subcanopy in small amounts. Shrub strata are absent to sparse and may, when present, include the above-listed taxa, <i>Morinda citrifolia</i>, and <i>Scaevola sericea</i>. The herbaceous stratum is similarly absent or sparse with <i>Batis maritima, Fimbristylis cymosa, Melinis repens, Passiflora foetida, Pennisetum ciliare</i>, and <i>Sesuvium portulacastrum</i> possibly present.

Comm #6908	Pinus ponderosa / Leymus salinus Woodland » more details accession code: VB.CC.31772.CEGL005362	Western Ecology Working Group of...	0	This open woodland is described only from Bryce Canyon National Park on the Paunsaugunt Plateau in southern Utah. This common woodland occurs on hillslopes, flat mesatops, in swales and valley bottoms, between 2136 and 2465 m in elevation, at all aspects. Soils range from rapidly drained loams and sandy loams to silty clays. The vegetation is characterized by the canopy tree <i>Pinus ponderosa</i> with 2-49% cover, and the medium-tall bunchgrass <i>Leymus salinus</i> that contributes 3-32% cover. Other trees present may include <i>Juniperus scopulorum, Pinus flexilis, Pinus edulis</i>, and <i>Pseudotsuga menziesii</i>. A few scattered shrubs may include <i>Ceanothus martinii, Chrysothamnus viscidiflorus, Purshia tridentata, Symphoricarpos oreophilus, Tetradymia canescens, Artemisia nova, Chrysothamnus depressus, Gutierrezia sarothrae</i>, and <i>Mahonia repens</i>. The herbaceous layer has sparse to moderate cover. Additional graminoids include <i>Achnatherum hymenoides, Carex rossii, Elymus elymoides, Hesperostipa comata, Koeleria macrantha</i>, and <i>Poa fendleriana</i>. Various forbs are also present at low cover, and a few stands have sparse cover of moss or biotic soil crust (dark cyanobacteria, lichens, and mosses).
