A forest health crisis of unprecedented proportions faced the Boise National Forest in the early years of the 1990's. Six years of drought set the stage for catastrophic outbreaks of insect and disease in the various tree communities of the forest, and wildfires burned hotter and more frequently than at any time in the past. In our often desperate search for ways to moderate the crisis, we turned to the notion of repeat photography to try to understand what happened in the past and how things are different now. We hoped to find some clues that would help shape management strategies that would increase forest and ecosystem resiliency to successfully fight drought and drought related problems.
