Yellowstone wolf reintroduction (1995-1996)
The US Fish and Wildlife Service captured 31 gray wolves in Canada and released them in Yellowstone National Park and central Idaho. It was the first time the species returned to the region in decades, following their near-total eradication in the Lower 48.
Wolf populations rebounded across the Northern Rockies over the following decade, reaching thousands of animals — but conflicts with ranchers grew as packs expanded onto grazing land.
Established the template for ESA recovery programs and set up the political fight over delisting that continues three decades later.
The executive order directly targets the recovery framework built by this reintroduction program, which is now the main source of conflict between conservation groups and ranchers.
