Grey Wolf Off Endangered Lists

More than four-thousand grey wolves in the upper Great Lakes region are going back on the US endangered species list -- at least for now.

The US Fish and Wildlife Service says it made a mistake by ending federal protection for wolves in Michigan, Minnesota and Wisconsin without public comment.

Under a settlement with five environmental groups which were suing the US government, the agency said it would return Great Lakes wolves to the list while considering its next move.

The wolves had been classified as endangered from 1974 until their removal in early May.
