A complete version of the Kaibab deer story and its history would be a valuable, realistic case study for ecology texts. An official website of the United States government. 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. 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). Water availability throughout seasonal ranges may be the limiting factor for this population.

In this classroom exercise we shall explore the Predator-Prey dynamics with the help of an ecological disaster that, had happened at Kaibab Plateau. Mule deer of the Kaibab North herd on the Kaibab Plateau are treasured for their historic and contemporary significance in North America. They are the densest population of mule deer in Arizona, with an estimate of 10,200 individuals in 2019. The range itself was damaged, and its carrying capacity was greatly reduced. We re-examined the case study by determining the age structure of aspen (Populus tremuloides Michx.) Some of the Kaibab herd winters in Utah, sharing winter range with Utahs Paunsaugunt Plateau herd. Portions of the Kaibab North herd in Arizona and the Paunsaugunt Plateau herd in Utah share a common winter range along the Arizona and Utah border. 4. Graph of Kaibab Deer Population.

Indian Institute of Management Calcutta Business Dynamics Course (MISM 271): 2019 - 20 Restoring ecological balance at Kaibab Plateau Purposes In this exercise you will have an opportunity of exploring a system dynamics model in terms of its structure and experiment with its behavior. There are currently few impediments to mule deer migration on the Kaibab Plateau. By the mid-1920s, many deer were starving to death. The Population of Kaibab Deer Versus Year graph models the They are the densest population of mule deer in Arizona, with an estimate of 10,200 individuals in 2019. Mule deer of the Kaibab North herd on the Kaibab Plateau are treasured for their historic and contemporary significance in North America.

The Kaibab North Deer herd winters among pinyon-juniper, sagebrush, and cliffrose landscapes along the west, east, and northern extents of the plateau. Due to banning hunting and killing predators the deer population began to rise drastically. From 1925 to 1940 there was still massive spike in the Kaibab population. mule-deer population on the Kaibab Plateau was rapidly expanding.

This report compiles two research efforts, the first completed by Arizona Game and Fish Department in 2014, and the second from Utah Division of Wildlife's ongoing research started in 2017.
