The American wolverine is on the knife’s edge of extinction, and it could be gone in a matter of years if we don't act fast.

Send a letter to the U.S. Fish and Wildlife Service today insisting that it protect this iconic species. Wolverines have enough fight left in them to pull through. But we have to give them the chance.

Scientists estimate their population in the lower 48 may be fewer than 300 animals. The snowpack they need to make dens and raise their young is disappearing due to climate change.

The Trump administration has betrayed these feisty snow-dwelling animals and repeatedly failed to make a listing decision. It's unacceptable. Wolverines can't afford to wait.

That's why we'll be going to court once again to fight for this species, which is so fierce it can turn away wolves and bears.

Trapping and habitat loss have dramatically shrunk wolverines' population. And global warming now threatens the deep snow they need to den and raise kits.

What's more, western states like Wyoming, Montana and Idaho oppose wolverine protection because it could restrict snowmobiling and winter recreation. But the science is clear on what these animals need to survive.

Tell the U.S. Fish and Wildlife Service to end the delays and grant American wolverines the lifesaving protection of the Endangered Species Act.
