Federal wildlife officials say the Prince of Wales flying squirrel doesn't warrant status as endangered or threatened.
The U.S. Fish and Wildlife Service announced its decision in a release Tuesday.
Officials said the petition for review presented 11 months ago from WildEarth Guardians didn't provide substantial information that the listing was warranted.
The service said the petition sought protections because of threats to old-growth forests and the flying squirrels' ability to get across large clear-cuts.
Officials say, however, that flying squirrels are not a species specific to old-growth forests. In fact, it found the Prince of Wales flying squirrel uses a variety of forested habitats.
