By 1924, it was obvious to men on the scene that a large-scale "die off and 4. lock ( Other periods of unusual numbers of aspen included high numbers of aspen dating to the 1880s and 1890s (when regular surface fires ceased), few aspen dating from 1953 to 1962 (after a second irruption of the deer population), and very high numbers from 1968 to 1992 (coincident with widespread logging). Share sensitive information only on official, read more. Their summer range consists of habitat dominated by ponderosa pine, mixed conifer, and aspen. There are currently few impediments to mule deer migration on the Kaibab Plateau. 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. 2. then there is a rapid decline between the year of 1924 and 1925. Hunting reopened during the fall of l924, killing 675 deer. Overall, there was no issue with the experiment. Water availability throughout seasonal ranges may be the limiting factor for this population. . The These data provide the location of migration routes for Mule Deer (Odocoileus hemionus) in the Kaibab North Herd in Arizona. Because these corridors traverse vast landscapes (i.e., up to 150 miles), they are increasingly threatened by roads, fencing, subdivisions and other development. The idea in 1906 was simply to protect and expand the herd, so on November 28, President Theodore Roosevelt created the Grand Canyon National Game Preserve. The Kaibab deer population was originally estimated to be 4,000 in the year of 1905. /. Graph data on the Kaibab deer population of Arizona from 1905 to 1939.

Binkley, D., Moore, M. M., Romme, W. H., & Brown, P. M. (2006). 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. 1. 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). 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. secure websites.

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 .gov website.
