Endangered and Threatened Wildlife and Plants; 12-Month Finding on a Petition to List the Island Marble Butterfly (Euchloe ausonides insulanus) as Threatened or Endangered

Résumé

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the island marble butterfly (Euchloe ausonides insulanus) under the Endangered Species Act of 1973, as amended (Act). After review of all available scientific and commercial information, we find that the petitioned action is not warranted. Furthermore, the Service and the National Park Service (NPS) have entered into a Conservation Agreement that implements conservation measures specifically addressing the needs of the island marble butterfly. We request that you submit any new information concerning the status of and threats to this subspecies whenever it becomes available. We will continue to collaborate with our partners to expand the conservation efforts that have been instituted by several landowners on currently occupied habitat.
