European Starling In Edwards Plateau

All regionsEdwards PlateauGeneralists

European Starling in Edwards Plateau has surged: up 655% on the route-weighted index since 1975.

+655%Since 1975TrendPercent 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 →

51YearsYears surveyedNumber of years with at least one standard-protocol run in this geography. A longer record makes the trend more reliable.Full methodology →

European Starling In Edwards Plateau Population Forecast

If the recent trend holds, European Starling in Edwards Plateau is projected to stay roughly flat through 2029, near 3.0 (95% range 0.21–5.9). A 5-year backtest shows a typical error of ±61.3%, with 100% of held-out values landing inside the 95% band.
