A Superior Accession of Western Honey Mesquite (Prosopis glandulosa var. torreyana) for Riparian Restoration Projects
An accession of western honey mesquite (Prosopis glandulosa var. torreyana) was identified at a riparian restoration project on the Gila River near Tacna in southwestern Arizona which grew faster than other honey mesquites at the same site. This "Tacna" accession appeared to be resistant t...
