The study design Summer range is dominated by a mix of ponderosa pine, spruce, fir, and aspen, interspersed with open meadows. 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. 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. 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). Based out of the Wyoming Cooperative Fish and Wildlife Research Unit, the team consists of federal scientists, university researchers, and biologists and analysts from participating state agencies.

By the early 1920s there was . 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.
