The U.S. Fish and Wildlife Service (FWS) says it’s now time to remove Yellowstone grizzly bears from the nation’s endangered and threatened wildlife list.

The agency says the bears have rebounded from an estimated 136 in 1975 to a population of more than 700 today.

“Our proposal today underscores and celebrates more than 30 years of collaboration with our trusted federal, state and tribal partners to address the unique habitat challenges of grizzlies,” said FWS Director Dan Ashe in a press release.

The iconic grizzlies — spread across Yellowstone in Montana, Wyoming, and Idaho — now range over more than 22,500 square miles of the park, FWS said.

Next comes a 60-day comment period on the proposed delisting, in which the public, federal and state agencies, and scientists can weigh in on either side of the proposal.

The FWS notes that even after the bear’s Endangered Species Act protections are removed it will closely monitor the grizzlies’ population and habitat.

“We will continue to be part of a strong monitoring program, implementation of the conservation strategy, and partnership with our state and federal partners,” Ashe said. “We are look forward to hearing from the public about the proposal and consulting with Native American tribes.”
