Aspen comprises the majority of deer browse in the summer, and the absence of a normal cohort of aspen from the 1920s would indicate deer overpopulation. kaibab deer reaches carrying capacity and the further effects of human interference on the This activity asks students to graph the number of Kaibab deer on the plateau after predators were removed. Other periods of unusual numbers of aspen included high numbers of aspen dating to the 1880s and 1890s (when regular surface fires ceased), few aspen dating from 1953 to 1962 (after a second irruption of the deer population), and very high numbers from 1968 to 1992 (coincident with widespread logging). Their summer range consists of habitat dominated by ponderosa pine, mixed conifer, and aspen. 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. however there was no hands on experiment which makes this study design observational. 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. Hunting was reopened, and during the fall of 1924, on the plateau.
