Climate Vulnerability Projections
Species distribution modeling results for Portland-area birds under SSP3-7.0 (2061-2080). Based on ensemble models trained on CHELSA bioclimatic variables.
Projected Habitat Suitability Change
Species Details
NE Portland Restoration Site
Bird Alliance of Oregon's new 12.5-acre site at NE 82nd Ave. Based on our climate projections, species most likely to benefit from habitat restoration at this site include those projected to maintain or increase suitability in the Portland metro area.
Top 5 resident/breeder species projected to benefit:
- Bushtit - year-round resident, +167% projected suitability
- Mallard - year-round resident, +146% projected suitability
- Killdeer - resident breeder, +102% projected suitability
- House Finch - year-round resident, +91% projected suitability
- Wood Duck - resident breeder, +110% projected suitability
These projections come from species distribution models (SDMs) covering 106 species from the eBird Basic Dataset (Oregon, Feb 2026 release). Each species was modeled using a 3-algorithm ensemble (Random Forest, Gradient Boosted Machines, Generalized Linear Models) with 3-fold spatial block cross-validation. Mean CBI across all species is 0.516.
Models were trained on CHELSA bioclimatic variables at ~1km resolution. Future projections use 4 GCMs across 4 SSPs (SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5) and 2 time periods (2041-2060, 2061-2080). Primary results shown here are for SSP3-7.0, 2061-2080.
Vulnerability classes are assigned based on the direction and magnitude of projected suitability change: "climate winner" species see increased habitat suitability, "stable" species show minimal change, "vulnerable" species face moderate declines, and "climate loser" species face severe projected declines.
Important: These are preliminary results from an ongoing research project. Model confidence varies by species, and projections should be interpreted as indicative of potential trends rather than definitive forecasts.
