A federal appeals court on Tuesday ruled against the Obama administration's 2011 decision to remove the gray wolf from protection under the Endangered Species Act.

The Interior Department "failed to reasonably analyze or consider two significant aspects of the rule — the impacts of partial delisting and of historical range loss on the already listed species," the D.C. Circuit Court of Appeals said in its decision. Tuesday's ruling vacates the Obama-era decision to delist the wolf species and puts the previous protections back in place, making the gray wolf the Trump administration's responsibility. The Interior Department has not said if it will appeal the ruling. The court ruled that the Fish and Wildlife Service's analysis was inadequate to make the determination that removed protections for the wolf species in nine states.
