Wildlife groups have sued the US government in an effort to protect the wolverine under the Endangered Species Act.
The US Fish and Wildlife Service denied the wolverine Endangered Species Act protection in March by saying that even if they disappeared from, the species would survive because of larger populations in Canada.
However, nine environmental groups are now suing the Interior Department in order to get the agency to reconsider its decision.
The US wolverine population consists of about 500 animals, inhabiting Montana, Idaho, Wyoming and Washington
David Gaillard, representative of Defenders of Wildlife, explained that climate change is a threat to the wolverines as they need alpine snow to rear their young successfully.
“Americans want these animals protected on our own soil,” he told the Associated Press.
In Canada, the population of the animal has been reduced in the past few years from 19,000 to 15,000.
