Red Wolf (Canis rufus)

More than 100 red wolves roam Alligator River National Wildlife Refuge in coastal North Carolina. That may not sound like many, but it’s the result of a successful reintroduction program. By the early 1980s only a few wolves remained in the wild—victims of hunting and habitat loss—and scientists captured the last 17, breeding them in captivity and then repopulating the refuge. But now there’s a new threat to the wolves: climate change and the resulting rise in sea levels may drown the wolves’ low-lying coastal home. But Alligator River scientists aren’t giving up. They’re using wetland-restoration techniques, including simple measures like planting soil-stabilizing trees, to protect the refuge from higher tides and stronger storms and give the area’s animals, including the wolves, time to move farther inland as the coastline shifts. – SZ
