Ants of 22 species were collected in can pit-traps from 16 different vegetative associations to determine distribution, seasonal and annual occurrence, and population as bases for monitoring environmental impact. Thirteen species were sufficiently abundant and distributed to qualify as indicator species. Myrmecocystus mexicanus was the most widespread ecologically. Pogonomyrmex occidentalis was the most abundant species, but second in ecological distribution. The greatest number of species was found in the juniper-Ephedra-grass association, and the fewest species in Ephredra-Coleogyne-Grayia.
