The Intermountain Adaptation Partnership (IAP) provided significant contributions to assist climate change response in national forests and national parks of the region. The effort synthesized the best available scientific information to assess climate change vulnerability, develop adaptation options, and catalyze a collaboration of land management agencies and stakeholders seeking to address climate change. The vulnerability assessment and corresponding adaptation options provided information to support national forests and national parks in implementing respective agency climate change strategies described in the National Roadmap for Responding to Climate Change (USDA FS 2010a), Climate Change Performance Scorecard (USDA FS 2010b) (Chapter 1), and National Park Service (NPS) Climate Change Response Strategy (NPS 2010). The IAP process allowed all forests in the U.S. Department of Agriculture Forest Service (USFS) Intermountain Region to respond with "yes" to element 6, Assessing Vulnerability, and element 7, Adaptation Actions, on their Climate Change Performance Scorecard. This, in turn, helped all forests to reach a minimum level of accomplishment of "yes" in 7 of 10 elements, with at least one "yes" in each of four dimensions. The IAP process also enabled participating national parks to make progress toward implementing several components (communication, science, adaptation goals) of the NPS Climate Change Response Strategy (NPS 2010).
