Pacific Northwest Salmon Vulnerability Maps for Climate Change Scenarios

Pacific Northwest steelhead salmon vulnerability to projected climate changes for 2030-2059. The dataset provides a spatially explicit assessment of exposure to increased temperatures and altered flows across four freshwater life stages. It was produced by NOAA's Northwest Fisheries Science Center.

Use Cases

• Prioritize habitat protection efforts based on relative rankings of exposure and sensitivity
• Model climate impact scenarios on salmon populations based on projected temperature and flow changes
• Design coordinated landscape-scale conservation actions based on combinations of exposure and sensitivity

Strengths

• Spatially explicit assessment covering the entire Pacific Northwest region
• Analysis considers four primary freshwater life stages: adult migration, spawning, incubation, and rearing
• Projections are based on a specific climate scenario for the years 2030-2059

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data format is PDF, which may limit direct computational analysis
