Climate change is one of the most pressing issues facing resource management. The disruptions it is causing require that we change the way we consider management in order to ensure the future of habitats, species, and human communities. Practitioners often struggle with how to identify and prioritize specific climate adaptation actions (CAAs). Management actions may have a higher probability of being successful if they are informed by available scientific knowledge and findings. The goal of the Available Science Assessment Process (ASAP) was to synthesize and evaluate the body of scientific knowledge on specific, on-the-ground CAAs to determine the conditions, timeframes, and geographic areas where particular CAAs may be most effective for resource managers. We have derived a methodology that utilizes literature reviews and interviews, an expert elicitation process, and extensive engagement with natural resource managers and scientists from federal, state, tribal, and private entities in Washington and Oregon working to address sea level rise. We convened a Scientific Expert Panel to provide independent scientific advice and recommendations to guide the project throughout its lifetime and evaluate the science behind specific CAAs. By evaluating actions on scientific knowledge and findings, we may be able to increase management effectiveness and efficiency.
