Description:A semiarid Chihuahuan Desert shrubland located in the USDA-ARS Walnut Gulch Experimental Watershed (WGEW) surrounding the town of Tombstone, AZ. The site vegetation is comprised of a diverse stand of mainly Chihuahuan desert shrub species like acacia constricta, larrea tridentata, and florensia cernua.
