Colubridae

In southern Arizona and northern Sonora, the neotropical vine snake (Oxybelis aeneus) lives in temperate oak woodland, canyon riparian woodland, desert-grassland, and pine-oak woodland communities at 1160 to 1650 m elevation. Perennial plants in an oak woodland habitat in the Atascosa Mountains in the center of the Arizona distribution of the species, have strong biogeographical affinities with the grasslands and woodlands of the southwestern United States and the northern Sierra Madre Occidental in Mexico.
