The restoration of historical fire regimes is often a primary objective in the conservation of fire-adapted forests. However, individual species’ responses to future climate change may uncouple historical vegetation–disturbance relationships, producing potentially negative ecological consequences to fire restoration. We used a landscape simulation model to assess how forest pattern will respond to future climate regimes and whether the restoration of historical fire regimes will benefit forest conservation under future climate regimes. Our study landscape was the 335,000-ha Kaibab Plateau at the North Rim of the Grand Canyon spanning a broad elevation-vegetation gradient of pinyon-juniper, ponderosa pine, mixed...

In ecology textbooks prior to the 1970s, Aldo Leopold's classic story of predator control, over-population 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. We re-examined the case study by determining the age structure of aspen (Populus tremuloides Michx.) on the plateau. 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 over-population. The number of aspen (at 1.4...
