CEGL005346 Prosopis velutina / Mimosa dysocarpa Ruderal Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Velvet Mesquite / Velvetpod Mimosa Ruderal Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland is described from the Las Guijas Mountains and the southeastern part of Buenos Aires National Wildlife Refuge in southern Arizona. Plot data indicate elevations of 1065-1110 m (3492-3652 feet) where it is found along drainages on gentle slopes. Soils are sandy loam or loam. The vegetation is characterized by an open to moderately dense (20-30% cover) tall-shrub canopy dominated by Prosopis velutina with an open to moderately dense (20-30% cover) dwarf-shrub layer dominated by Mimosa dysocarpa, sometimes with high cover of Gutierrezia sarothrae. The herbaceous layer has high species richness of forbs (>25 species) but relatively low cover (20%). Cover is codominated by graminoids and forbs. Characteristic species include Bouteloua aristidoides, Bouteloua curtipendula, Panicum hirticaule, Ambrosia confertiflora, Chamaesyce albomarginata, Evolvulus alsinoides, Gutierrezia microcephala, Ipomoea hederacea, Mollugo verticillata, and Phemeranthus aurantiacus. If present, Eragrostis lehmanniana cover is low (less than 25% cover and less than a third of the total perennial graminoid cover).
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This vegetation appears to generally occur in saline situations, possibly with a permanently high water table, but where surface water rarely occurs (and when it does for short duration). Placement in an upland alliance may be preferable.
