  1. Southeast Integrated Climate Assessment Participants Auburn University North Carolina State University Penn St. University Texas Tech. University University of Georgia USGS CO, FL, GA, MD, MN, LA, MS

  2. Southeast Integrated Climate Assessment • Regionally downscaled probabilistic climate change projections • Integrated Coastal Assessment – Southeastern Pilot • Climate change and its impacts on bird habitats • Designing sustainable landscapes: climate and land use change projected impacts on priorities species habitats • Patch and range dynamics of North American avian species in response to land use patterns and climatic change • Multi-resolution assessment of potential climate change effects on biological resources: Aquatic and hydrologic dynamics • Optimal conservation strategies to cope with climate change

  3. Historic LULC Trends (Grand) Downscaled Climate Change Projections (Hayhoe) Avian Range Dynamics (Collazo, Nichols) Optimal Conservation Strategies (Grand et al.) Designing Sustainable Landscapes (McKerrow) Probabilistic Climate Change Projections (Haran) Watershed Model (Hay) ACF Aquatics (Peterson) Coastal Sea Level Rise (Burkett)

  4. Southeast Integrated Climate Assessment • Regionally downscaled probabilistic climate change projections • Development and Dissemination of High-Resolution National Climate Change Dataset • Integrated Coastal Assessment – Southeastern Pilot • develop a Bayesian statistical framework for predicting coastal erosion and inundation under a range of sea level rise scenarios and considering the combined effects of geologic constraints and other driving forces, • assess the potential impacts of sea level rise on coastal ecosystems and related wildlife resources, and • develop visualization products that will help natural resource managers anticipate sea level rise and adapt to the changes that are projected over the coming decades.

  7. Optimal conservation strategies for dynamic landscapes Incorporating climate change and urban growth in conservation planning James B. Grand, USGSAlabama Cooperative Fish and Wildlife Research Unit

  8. When to act? Adapted from: Lawler, J.J., 2009

  9. Adaptation strategies • Resistance – ability to remain unchanged • Resilience – ability to recover from perturbation • Change – help systems move from one state to another Lawler, J.J., 2009. Climate Change Adaptation Strategies for Resource Management and Conservation Planning. The year in ecology and conservation biology, 2009. New York Acad. Sci. 1162:79-98.

  10. Restoring habitat & system dynamics • Current restoration strategies: • Return system to historic conditions • Return community to historic assemblage • Climate-forced paradigm shifts? • Restore ecosystem processes • Focus on abiotic aspects • Allow species assemblages to fluctuate

  11. Competing hypotheses & uncertainty • Climate models? • Which one(s)? • Projections versus predictions • Habitat responses - driving influences • Fire frequency • Insect outbreaks • Drought • Temperature • Invasive species • Wildlife responses?

  12. Structured decision making Problem Decision Objectives Optimization & Tradeoffs Alternatives Consequences

  13. Optimization & adaptive framework Strategic Habitat Conservation Adaptive Management

  14. Scope & timeline • Workshops • Project – blue line • Organized roughly by ecoregions • Completed by mid-2010 • Decision model • Framework 2012 • Fully parameterized 2015
