All regionsPiedmontGrassland birds

Ring-necked Pheasant in Piedmont has collapsed: down 100% on the route-weighted index since 1968.

-100%Since 1968TrendPercent change in the route-weighted abundance index between a smoothed baseline window and the most recent one. It tracks direction, not absolute population.Full methodology →

54YearsYears surveyedNumber of years with at least one standard-protocol run in this geography. A longer record makes the trend more reliable.Full methodology →
