Due to the ban from hunting and the removal exponential line from 1905 to 1924. Once ecologists began to study the area and reflect on the changes that had occurred there, they began to use the Kaibab deer as a simple lesson about how the removal of the deer's natural predators, which had been done in the interest of preserving the deer population, had allowed the deer to overreproduce, and quickly overwhelm the plateau's resources.

In 2019, the team completed analyses necessary to map corridors, stopovers, and winter ranges in Arizona, Idaho, Nevada, Utah, and Wyoming. They were developed using 96 migration sequences collected from a sample size of 41 adult mule deer comprising GPS locations collected every 2-6 hours. The Ungulate Migrations of the Western United States report and associated map archive provides the means for corridors to be taken into account by state and federal transportation officials, land and wildlife managers, planners, and other conservationists working to maintain big game corridors in the western states. We re-examined the case study by determining the age structure of aspen (Populus tremuloides Michx.) Since the actual numbers of deer and predators will never be known for certain, such a simplistic account of the changes on the Kaibab Plateau cannot be considered a reliable ecological lesson.

Perversely enough, the more deer that have been shot off, the better the fawn crop. In, the absence of predation by its natural predators (cougars, wolves, coyotes) or by man as a hunter, the herd reached, 100,000 in 1924; in the absence of sufficient food, 60 percent of the herd died off in two successive winters.
