Name: Celtis laevigata var. reticulata Shrubland Alliance Reference: Western Ecology Working Group of... Description: This alliance occurs on alluvial terraces along the drainages that dissect the upper bajadas and lower canyons in central and south-central Arizona and in southwestern New Mexico. Stands are restricted to the corridors of intermittent streams by the arid upland environment. Sites are typically flat to gently sloping with northern and eastern aspects. Substrates are generally well-drained, coarse-textured soils. This relatively mesic shrubland alliance utilizes moisture from the water table and is dependent on intermittent flows or occasional flooding of washes to supplement soil moisture and maintain groundwater levels. Vegetation included in this alliance has a sparse to dense upper canopy of deciduous shrubs that is dominated by Celtis laevigata var. reticulata. Other tall shrubs may includeProsopis velutina orQuercus grisea. A sparse to moderately dense understory of short and dwarf-shrubs is usually present, includingCeltis pallida, Lycium spp.,Rhus trilobata, Mimosa spp., and many others. The herbaceous component is usually a sparse layer of mixed perennial graminoids and forbs, but seasonally may have dense cover of annual species. Diagnostic of this riparian shrubland alliance is the dominance of the tall shrub Celtis laevigata var. reticulata.  Accession Code: VB.CC.21425.CELTISLAEVIGATA Plot-observations of this Community Concept: 0
