Prehistoric horticulturalists of the American Southwest relied on crop complexes for much of their vegetal diet, but also relied heavily on hunting and trapping. Permanent settlement by the Mogollon resulted in resource depression of larger animal taxa (primarily artiodactyls) in some areas that could not withstand sustained human predation. This resulted in the predation of smaller animals (primarily jackrabbits, cottontail rabbits, and rodents) that could withstand intensive predation. The extent to which small animal taxa were incorporated into the prehistoric food regime is closely tied to the inability of the site catchment environments to support viable populations of larger taxa capable of withstanding human predation. This scenario is exemplified by five Mogollon sites from western and southwestern New Mexico.
