1. This is slide one Sea-Level Rise and Coastal Habitats of the Pacific Northwest: Application of a Model A Presentation for the 2009 Puget Sound Georgia Basin Ecosystem Conference, Seattle, WA Patty Glick Senior Global Warming Specialist National Wildlife Federation

2. Sea-level rise is direct and certain A Focus on Sea-Level Rise Important coastal habitats are at risk Coastal communities are at risk

3. Sea Level Affecting Marshes Model (SLAMM), Version 5.0

4. Data inputs: Regional Light-imaging Detection and Ranging (LiDAR) data FWS National Wetlands Inventory Data (Multiple Habitat Types) USGS Digital Elevation Model data NOAA Tidal Data

5. Sea Level Affecting Marshes Model (SLAMM), Version 5.0 Multiple Scenarios, Localized Changes Accelerated sea-level rise (25-year time steps) (eustatic sea-level rise) Site-specific sedimentation, accretion rates and geological factors (relative sea- level rise)

6. Sea Level Affecting Marshes Model (SLAMM), Version 5.0 Addresses five primary processes that affect coastal habitat: Inundation Erosion Overwash Saturation Estuarine Salinity (NEW)

7. Additional Information Needs Localized geomorphology, dynamic accretion processes More detailed coastal elevation data (LiDAR) (some areas) Specific impacts on species and ecosystems We Cannot Let Remaining Uncertainty Delay Action! Interaction with additional climate and non-climate stressors

14. Adaptation Strategies Identify and prioritize potential areas for upland protection (e.g., marginal agricultural land) as an ecological buffer Focus restoration on “protective” habitats such as dunes, riparian vegetation Move, abandon, and/or maintain shoreline infrastructure (considering trade-offs between habitat protection, agriculture, development)
