The southeastern U.S. contains highly diverse ecosystems that are increasingly threatened by human-induced environmental changes and that require increasingly intensive management to avoid negative impacts on native biota. Climate change is one aspect of landscape alteration that is particularly challenging to conservation planners and managers. Previous conservation planning efforts identified and prioritized areas for conservation based on current environmental conditions, such as habitat quality, and assumed that conditions in conservation lands would be largely controlled by management actions (including no action). Climate change, however, will likely alter important system drivers (e.g., temperature, precipitation, and sea level [...]
