The U.S. Forest Service Rocky Mountains Research Center has developed a useful factsheet on the Arizona Sky Islands. The brief discusses Climate Change, Carbon, Fire, and Ecological Transition in the Sky Islands' ecosystem. Rocky Mountain Research Station research ecologists used an ecosystem process model to examine the potential for prescribed fuel treatments to mitigate the effects of climate and fire in the Huachuca Mountains. The team found that the forests of the Huachuca Mountains may transition from a carbon-neutral system to a significant carbon source over the coming decades, and simulated the effects that fuel treatment could have on tree mortality.
