If the carrying capacity was 30,000 the 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). These data provide the location of migration routes for Mule Deer (Odocoileus hemionus) in the Kaibab North Herd in Arizona. @article{f60c15e87ec84b83932cdeb6ed4a9bee.

In ecology textbooks prior to the 1970s, Aldo Leopold's classic story of predator control, overpopulation of deer, and habitat degradation on the Kaibab Plateau during the 1920s epitomized predator regulation of herbivore populations.

The blue dots representing the actual population of the kaibab deer lines up with the We re-examined the case study by determining the age structure of aspen (Populus tremuloides Michx.) Once ecologists began to study the area and reflect on the changes that had occurred there, they began to use the Kaibab deer as a simple lesson about how the removal of the deer's natural predators, which had been done in the interest of preserving the deer population, had allowed the deer to overreproduce, and quickly overwhelm the plateau's resources. the deer population might have been, the Kaibab deer story is an excellent example of the interaction of science, conservation, politics, and management. Hunting was reopened, and during the fall of 1924, 675 deer were The Kaibab North Deer herd winters among pinyon-juniper, sagebrush, and cliffrose landscapes along the west, east, and northern extents of the plateau. This number was never confirmed by any kind of count or survey, and has become an accepted number mainly because no other estimate is available. Moderately because the population of the deer grew.

Mule deer of the Kaibab North herd on the Kaibab Plateau are treasured for their historic and contemporary significance in North America. However, the story disappeared from texts in the late 20th century after several papers noted uncertainties in . 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. 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). Offices & Visitor Centers. 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. consumption of vegetation by the deer. They were developed using 96 migration sequences collected from a sample size of 41 adult mule deer comprising GPS locations collected every 2-6 hours. Together they form a unique fingerprint. Perversely enough, the more deer that have been shot off, the better the fawn crop. The study design The range itself was damaged, and its carrying capacity was greatly reduced.
