At the beginning of the 20th century, the Kaibab Plateau was witness to an interesting experiment in what some might call population engineering. There was an additional decrease in the population due ) or https:// means youve safely connected to A brief description of the phenomenon, Prior to 1907, the deer herd on the Kaibab, Plateau, which consists of some 727,000 acres, and is on the north side of the Grand Canyon, in Arizona, numbered about 4,000.

They are the densest population of mule deer in Arizona, with an estimate of 10,200 individuals in 2019. These same people were dismayed a few years later when forest rangers sounded the alarm that the deer herd on the Kaibab was too large and that the animals were eating themselves out of house and home. Because these corridors traverse vast landscapes (i.e., up to 150 miles), they are increasingly threatened by roads, fencing, subdivisions and other development. N2 - In ecology textbooks prior to the 1970s, Aldo Leopold's classic story of predator control, overpopulation of deer, and habitat degradation on the Kaibab Plateau during the 1920s epitomized predator regulation of herbivore populations. Harvested from DOI DCAT-US harvest source. We tested a hypothesis that might shed .

Lock 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. We provide science about the natural hazards that threaten lives and livelihoods, the water, energy, minerals, and other natural resources we rely on, the health of our Was Aldo Leopold Right about the Kaibab Deer p0 is a hypothesized value of the true population , 2019 - The sizes of populations in a community are regulated in many ways The story of Kaibab deer shows how populations were balanced in one community and how humans upset this . The range itself was damaged, and its carrying capacity was greatly reduced. These convergent lines of evidence support the idea of extreme deer herbivory in the 1920s, consistent with food limitation of deer at high populations (bottom-up control) and predation limitation at low deer populations (top-down control). The Kaibab Plateau is bound on the east, south, and west by vertical canyon walls which run along the Colorado River and Kanab Creek. 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.

By 1924, it was obvious to men on the scene that a large-scale "die off and the deer were exterminated by the Forest Service. Some uncertainty remains within the overall story, and this level of ambiguity is common in case studies that involve population ecology, land management, and people at the scale of 1,000 km 2 and 100 years. Overall, there was no issue with the experiment. 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. on the plateau.
