Adapting natural resource management to climate change: the Blue Mountains and Northern Rockies Adaptation Partnerships Jessica E. Halofsky¹ and David L. Peterson² ¹University of Washington, School of Environmental and Forest Sciences ²USDA Forest Service, Pacific Northwest Research Station The Blue Mountains and Northern Rockies Adaptation Partnerships Forest Service led sciencemanagement partnerships with the goals of: • Increasing climate change awareness • Assessing vulnerability of natural resources • Developing adaptation strategies and tactics Climate Change Adaptation in the U.S. Forest Service The Blue Mountains Adaptation Partnership • Involved three national forests • Included vulnerability assessments for: • Hydrology • Water use and infrastructure • Fisheries • Vegetation and disturbance The Northern Rockies Adaptation Partnership • A regional-scale assessment • Involved 16 national forests and three national parks • Included - Water vulnerability - Fisheries assessments for: - Vegetation - Wildlife - Recreation - Ecosystem - Disturbance services General Approach Establish a sciencemanagement partnership Conduct a vulnerability assessment Identify adaptation strategies and tactics in workshops Develop and publish a peerreviewed report Assessing Climate Change Vulnerability Workshop Objectives • Downscale information from the regional assessment to the subregional and unit scales • Develop potential adaptation strategies and tactics to promote resilience, facilitate transitions, or maintain status “Downscaling” the Vulnerability Assessment • Describe any geographic variation in sensitivity to climate or adaptive capacity that is not incorporated in the summary. • Are there local features in your region that would alter the predicted climate trends? • Are there places on the ground where the resource is more, or less, sensitive to climate change due to overlapping risks? Development of adaptation strategies and tactics by resource managers Expected Outcome Increased insect outbreaks Adaptation Strategy Increase individual tree vigor and increase species and structural diversity Adaptation Tactic Barriers Conduct thinning to promote late seral forest conditions Funding to conduct treatments Incorporate gap creation in thinning treatments to increase species diversity Results: Infrastructure in the Blue Mountains • Sensitivity: Higher peak flows will lead to increased road damage • Adaptation strategy: Increase resilience of infrastructure to higher peak flows • Adaptation tactics: • Replace culverts with higher capacity culverts or other appropriate drainage (e.g., fords or dips) in high-risk locations • Complete geospatial database of culverts and bridges Assessing vulnerabilities: roads near streams Results: Fish in the Blue Mountains • Sensitivity: Stream temperatures will increase, affecting many life stages of aquatic organisms. • Adaptation strategy: Maintain or restore natural thermal conditions to buffer against future change • Adaptation tactics: • Maintain or restore riparian vegetation to ensure channels are not exposed to increased solar radiation • Increase floodplain connectivity, diversity, and water storage to improve hyporheic and base flow conditions Results: Forests in the Northern Rockies • Sensitivity: Increased risk of mortality from fire and drought in dry forests • Adaptation strategy: Decrease forest density, and increase structural diversity • Adaptation tactics: • Reduce forest density with thinning, prescribed fire, and wildfire use • Promote age class and structural diversity across the landscape with regeneration harvest, thinning, prescribed fire, and wildfire use Results: Winter Recreation in the Northern Rockies • Sensitivity: Shorter winters with less snow, and wetter or icier snow; infrastructure may not be where the snow persists • Adaptation strategy: Increase recreation management flexibility • Adaptation tactics: • Maintain current infrastructure and expand facilities in areas where concentrated use increases • Develop options for diversifying snow-based recreation (e.g., additional lifts, helicopter skiing, toboggan runs) Products: Science-Based, PeerReviewed Reports For more information: www.adaptationpartners.org
