Name: Prosopis (glandulosa, velutina) Woodland Alliance Reference: Western Ecology Working Group of... Description: This alliance occurs in southern California, Arizona, and possibly southwestern New Mexico and adjacent Mexico on a variety of sites. Sites include mesic areas such as floodplains, streambanks, intermittently flooded arroyo terraces, alkali sinks and washes, and extends into the upland on dry terraces above streams and arroyos. Substrates are generally coarse-textured, gravelly alluvium. Prosopis spp. trees extract groundwater with extensive root systems, but grow best where water tables are shallow such as along drainages. Woodlands included in this alliance are characterized by a moderate to dense tall woody canopy dominated by Prosopis glandulosa and/or Prosopis velutina. The diversity of other species can vary greatly with geography and substrate. The dominant understory shrubs are often species of Atriplex, but may include many other species. Succulents may include several species of Opuntia and Yucca. The herbaceous layer is variable from moderately dense to nearly absent. Characteristic perennial grasses may include Aristida spp., Bouteloua spp., Buchloe dactyloides, Pleuraphis mutica (= Hilaria mutica), Muhlenbergia porteri, and Sporobolus spp. Sparse annual grasses may also be present. Forb cover is also sparse, but it can be relatively diverse. Common forbs may include species of Amaranthus, Chenopodium, Croton, Eriogonum, Euphorbia, Solanum, and Zinnia. Diagnostic of this woodland alliance is the dominance of tree-sized Prosopis glandulosa or Prosopis velutina in the upper canopy.  Accession Code: VB.CC.25919.PROSOPISGLANDUL Plot-observations of this Community Concept: 0
