All statesGeneralists

Common Ground Dove in Louisiana has collapsed: down 86% on the route-weighted index since 1972.

-86%Since 1972TrendPercent 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 →

29YearsYears surveyedNumber of years with at least one standard-protocol run in this geography. A longer record makes the trend more reliable.Full methodology →
