Sources and method
- Boundary: Washington Department of Fish and Wildlife (WDFW), the same layer the WikiHunt map draws.
- Public land: USGS Protected Areas Database (PAD-US) 4.1, Fee Managers layer (public domain).
- Method: the unit and PAD-US polygons are simplified to about 100 m and measured on a grid of about 250 cells across the unit, so overlapping records are counted once. Expect about ±1 percentage point.
- Season dates: WikiHunt’s season table, updated Sep 2, 2026, checked against each state’s published regulations. Dates change; the regulations win.
