And that you probably love animals. 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 over-reproduce, and quickly overwhelm the plateau's resources. Hunters were prohibited from shooting deer, but they were allowed to shoot the deer’s predators, including cougars and coyotes. deer was to ban all hunting.
