Name: Prosopis velutina - Acacia greggii Woodland Reference: Western Ecology Working Group of... Description: This riparian woodland is described from southern Arizona. Plot data from Buenos Aires National Wildlife Refuge indicate an elevational range of 970-1030 m (3200-3700 feet) where it is found on gentle slopes along drainages and in floodplains on valley floors. The alluvial soils are variable and range from sand to clay textures. The vegetation is characterized by a moderately dense to dense tree canopy codominated by <i>Prosopis velutina</i> and <i>Acacia greggii</i>. Scattered short shrubs may be present but are generally not dense enough to form strata. Common shrubs may include <i>Baccharis emoryi, Baccharis sarothroides, Calliandra eriophylla, Celtis pallida, Lycium andersonii, Mimosa aculeaticarpa var. biuncifera (= Mimosa biuncifera), Mimosa dysocarpa</i>, and <i>Opuntia spinosior</i>. The open to dense (20-80% cover) herbaceous layer is dominated by a mixture of grasses and forbs. The native annual forb <i>Amaranthus palmeri</i> may be present but does not codominate the herbaceous layer. Associated herbaceous species include <i>Aristida ternipes, Boerhavia</i> spp., <i>Bouteloua aristidoides, Bouteloua curtipendula, Chloris virgata, Digitaria californica, Ipomoea hederacea, Kallstroemia grandiflora, Panicum hirticaule, Proboscidea parviflora</i>, and <i>Tidestromia lanuginosa</i>. If present, <i>Eragrostis lehmanniana</i> cover is low, with less than 25% cover and less than a third of the total perennial graminoid cover.  Accession Code: VB.CC.31760.CEGL005340 Plot-observations of this Community Concept: 0
