A petition for ESA protections for the wolverine was first filed in 2000. The Service deemed that petition lacked the adequate evidence to justify listing the animal. The decision was overturned by a federal court in 2006. The Service then issued a negative 12-month finding in 2008, which was challenged in court resulting in a settlement that led to a new finding that wolverine should be protected under the ESA, but that other priorities precluded the listing at that time. A landmark settlement with WildEarth Guardians, which resolves the backlog of imperiled species awaiting protections, then guaranteed a new finding for the wolverine. In February 2013, the Service proposed listing the wolverine as “threatened” under the ESA. In August 2014, however, the Service reversed course and issued a decision not to list the species, contradicting its own expert scientists’ recommendations. The ruling is in response to the organizations’ legal challenge to that decision. The ruling reinstates the proposed listing rule and requires the Service to make a new final determination.
