There’s been some conservation wins that I know of. Okaloosa Darter fish came off of endangered status, and eventually off of threatened The Red Cockaded Woodpecker was elevated from endangered to threatened a few years ago.
Controlled burns in the US long leaf pine forests have also lead to a return of the quail population.
Just trying to sprinkle a little good news out there.
