The Arizona Strip and Kaibab Plateau have long been hailed as the world’s premier areas to hunt for trophy mule deer and boast an impressive track record of producing giant mule deer bucks for the hunters that are lucky enough to draw tags in these world famous trophy mule deer hunting areas. The deer population continued to decline despite these efforts, and over the next two winters, it is estimated that 60,000 deer starved to death – nearly 15 times that of the original population. A mule deer herd exists on the northern rim of the Grand Canyon, located on the North Kaibab Plateau.

What major lessons were learned from the Kaibab deer experience? 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. As ecologists argue today, that relationship between predator and prey is not always so firm, and the idea of balance in nature is equally suspect.

A complete version of the Kaibab deer story and its history would be a valuable, realistic case study for ecology texts. What we can do... To keep the deer population stable in the future we can continue to regulate hunting, instead of killing off predators we can keep smaller numbers of them in the ecosystem, and can also try and control the birth rate of the deer so that they do not run out of I suggest that the agreed values become a standard for mule deer in the Southwestern U.S. As excess dietary N is converted to a caloric resource, a continual state of under-nutrition exists for the deer upon entering the N.

Name LAB: THE LESSON OF THE KAIBAB Predators were removed as a way to increase deer populations, but may have had the opposite effect. This particular fluctuation is a great example of population engineering and the effects humans can have on nature. The overgrazing reduced food to support a carrying capacity of 30,000, when the herd grew to 100,000 it kept reducing food supply. The Forest Service reduced the number of livestock grazing permits. The department had proposed two juniors-only antlerless deer hunts, with 800 permits total, be established to curtail the expanding deer population on what is described as the state’s best deer herd. Overpopulation occurred, so the deer starved to death. North Kaibab mule deer. Scientists estimated the total average carrying capacity of the Kaibab plateau was about 30,000 deer. The Kaibab deer are particularly important because of the changes in their population during the early 1900s. Taught land managers that there is a fine balance that must be managed between carrying capacity, food, source, climate, hunting and/or predators.
