Binkley, D., Moore, M. M., Romme, W. H., & Brown, P. M. (2006). The Kaibab North Deer herd winters among pinyon-juniper, sagebrush, and cliffrose landscapes along the west, east, and northern extents of the plateau. There are currently few impediments to mule deer migration on the Kaibab Plateau. population continued to decline after it reached that level in the late 1920s was because of over The Kaibab Plateau is bound on the east, south, and west by vertical canyon walls which run along the Colorado River and Kanab Creek. Annually the Kaibab herd migrates an average of 27 mi (43 km) between summer and winter range. The Kaibab Deer Investigating Committee recommended that all livestock not owned by local residents be removed immediately from the range and that the number of deer be cut in half as quickly as possible. A complete version of the Kaibab deer story and its history would be a valuable, realistic case study for ecology texts. The number of aspen (at 1.4 m) dating to the 1920s was an order of magnitude lower than the null expectation. Hunting was reopened, and during the fall of 1924, 675 deer were Mule deer (Odocoileus hemionus) of the Kaibab Plateau in Arizona had a population estimate of 10,200 individuals in 2019. The deer population experienced a great increase in numbers during the early decades of the 20th century. A complete version of the Kaibab deer story and its history would be a valuable, realistic case study for ecology texts. In the next two winters with this new over-population---- over 60,000 deer starved to death. Together they form a unique fingerprint. Conclusion: Some of the Kaibab herd winters in Utah, sharing winter range with Utahs Paunsaugunt Plateau herd. The Kaibab North Deer herd winters among pinyon-juniper, sagebrush, and cliffrose landscapes along the west, east, and northern extents of the plateau. In 2019, the team completed analyses necessary to map corridors, stopovers, and winter ranges in Arizona, Idaho, Nevada, Utah, and Wyoming. .gov website belongs to an official government The Kaibab Plateau is bound on the east, south, and west by vertical canyon walls which run along the Colorado River and Kanab Creek. Mule deer of the Kaibab North herd on the Kaibab Plateau are treasured for their historic and contemporary significance in North America. Over the last decade, many new tracking studies have been conducted on migratory herds, and analytical methods have been developed that allow for population-level corridors and stopovers to be mapped and prioritized. 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. Shortly after that time, however, the deer population did begin to decline from overbrowsing. Their summer range consists of habitat dominated by ponderosa pine, mixed conifer, and aspen. reopening of hunting and then the over consumption of vegetation.

Because these corridors traverse vast landscapes (i.e., up to 150 miles), they are increasingly threatened by roads, fencing, subdivisions and other development. In 2018, the U.S. Geological Survey assembled a Corridor Mapping Team to provide technical assistance to western states working to map bison, elk, moose, mule deer, and pronghorn corridors using existing GPS data.

As a result, the deer population was well below its carrying capacity of 30,000. However, the story disappeared from texts in the late 20th century after several papers noted uncertainties in estimations of the deer population and provided alternative explanations.

For example, how hunting and natural predators keep the deer population Some ecologists suggested that the situation highlighted the importance of keeping a population in balance with its environment's carrying capacity. The plateau's pre-1905 population of mule deer was estimated to be around 4,000. Based out of the Wyoming Cooperative Fish and Wildlife Research Unit, the team consists of federal scientists, university researchers, and biologists and analysts from participating state agencies.
