Again, there was no systematic survey to support this estimate, which may have been exaggerated to twice the actual number. By, then, the girdling of so much of the vegetation through browsing precluded recovery of the food reserve to such an, extent that subsequent die-off and reduced natality yielded a population about half that which could theoretically, have been previously maintained.

The initial decrease in the secure websites. lock ( N2 - 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. 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. 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.
