By the mid-1920s, many deer were starving to death. Perversely enough, the more deer that have been shot off, the better the fawn crop. Harvested from DOI DCAT-US harvest source. a gradual decrease in the population of the kaibab deer. lock ( 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). to get the population back under control. Water availability throughout seasonal ranges may be the limiting factor for this population. The graph does match the density This increased the need for food, and because of this demand, nearly 60,000 deer starved to death in the time span of two winters.
