Wolverines threatened with extinction as climate change melts their snowy mountain refuges, US says

The North American wolverine will receive long-delayed federal protections under a Biden administration proposal

The North American wolverine will receive long-delayed federal protections under a Biden administration proposal released Wednesday in response to scientists warning that climate change will likely melt away the rare species’ snowy mountain refuges.

Across most of the U.S., wolverines were wiped out by the early 1900s from unregulated trapping and poisoning campaigns. About 300 surviving animals in the contiguous U.S. live in fragmented, isolated groups at high elevations.

In the coming decades, warming temperatures are expected to shrink the mountain snowpack wolverines rely on to dig dens where they birth and raise their young.

The decision Wednesday by the U.S. Fish and Wildlife Service follows more than two decades of disputes over the risks of climate change, and threats to the long-term survival of the elusive species.

The animals resemble a small bear and are the world’s largest species of terrestrial weasels. They are sometimes called “mountain devils” for their ability to thrive in harsh alpine environments.

Protections were rejected under former President Donald Trump. A federal judge in 2022 ordered the administration of President Joe Biden to make a final decision this week on whether to seek protections.
