Pearl Harbor National Wildlife Refuge

The Pearl Harbor National Wildlife Refuge is a United States National Wildlife Refuge on the island of Oʻahu, Hawaii. It was created in 1972 to mitigate the wildlife resource disturbances caused by construction of the Honolulu International Airport Reef Runway. The Refuge includes three units, the Honouliuli, Waiwa and Kalaeloa. The Honouliuli and Waiawa Units are managed under a cooperative agreement with the United States Navy. The Kalaeloa Unit was established during Base Realignment and Closure proceedings in 2001. Through these cooperative efforts with the Federal Aviation Administration, the State of Hawaii, and the U.S. Navy, the U.S. Fish and Wildlife Service made Pearl Harbor NWR a reality.
