Environmentalists this week escalated their campaign against the Fish and Wildlife Service for allegedly missing Endangered Species Act deadlines, this time in a case involving threatened North American wolverines.

In its sixth missed-deadline lawsuit filed this year, the Center for Biological Diversity called the federal agency to account for failing to designate the wolverine’s critical habitat within the time allowed under the ESA.

“The Fish and Wildlife Service’s delay in protecting the wild places that wolverines call home threatens to push them closer to extinction,” Andrea Zaccardi, carnivore conservation legal director at the center, said in a statement.

Zaccardi added that “in the face of climate change, it’s crucial to protect the rugged, snowy areas that the wolverine needs to survive.”
