Their summer range consists of habitat dominated by ponderosa pine, mixed conifer, and aspen. p0 is a hypothesized value of the true population Government efforts, led by the United States Forest Service, began to protect the deer's numbers by killing off their natural predators once again; to this end, between 1907 and 1939, 816 mountain lions, 20 wolves, 7388 coyotes and over 500 bobcats were reportedly killed. The deer population experienced a great increase in numbers during the early decades of the 20th century. Water availability throughout seasonal ranges may be the limiting factor for this population. They were developed from Brownian bridge movement models using 44 winter sequences collected from a sample size of 30 adult mule deer comprising GPS locations collected every 2-6 hours.

Objectives: Graph data on the Kaibab deer population of Arizona from 1905 to 1939 Determine factors responsible for the changing populations Determine the carrying capacity of the Kaibab Plateau Background Before 1905, the deer on the Kaibab Plateau were estimated to number about 4000. Annually the Kaibab herd migrates an average of 27 mi (43 km) between summer and winter range. Specifically, the ban on hunting and removal of natural predators which caused a But this was only "one-tenth" of the number of deer born that year. proportion P. K is carrying capacity (approximately 40,000). The average carrying capacity of the land was unknown, in part because this concept was not widely used by naturalists at the time. It can be seen increasing from the year 1905 to 1924 and The Ungulate Migrations of the Western United States report and associated map archive provides the means for corridors to be taken into account by state and federal transportation officials, land and wildlife managers, planners, and other conservationists working to maintain big game corridors in the western states. Perhaps the most pertinent statement relative to the matter of the inter-regulatory, effect of predator and prey is the following by Aldo Leopold, one of the most significant of recent figures on the, There is no record of a deer irruption in North America antedating the removal of deer predators. the .gov website. Changes take place, sometimes rapidly, but their effects linger for decades. Because these corridors traverse vast landscapes (i.e., up to 150 miles), they are increasingly threatened by roads, fencing, subdivisions and other development. Binkley, Dan, et al. measures the strength and direction of a linear relationship between variables on a scatter plot. The more meaningful lesson of the Kaibab suggests that human efforts to protect wildlife and preserve wild areas must be balanced with ecological complexity and social priorities that are difficult to predict.

One estimate put the population as high as 100,000 deer inhabiting the range in 1924. Year This report compiles two research efforts, the first completed by Arizona Game and Fish Department in 2014, and the second from Utah Division of Wildlifes ongoing research started in 2017. In ecology textbooks prior to the 1970s, Aldo Leopold's classic story of predator control, over-population of deer, and habitat degradation on the Kaibab Plateau during the 1920s epitomized predator regulation of herbivore populations. consumption of vegetation by the deer.
