Johnston Atoll National Wildlife Refuge is located in the central Pacific Ocean, 717 nautical miles west-southwest of Honolulu. The refuge is managed for 14 species of breeding sea birds and 5 species of wintering shorebirds, and for its coral reef and diverse marine organisms, including the threatened green sea turtle. The atoll comprises four small islands (696 acres), which constitute the only land area in over 800,000 square miles of ocean. The emergent land associated with this refuge provides critical, rat-free habitat for central Pacific sea bird populations; its coral reef ecosystem is an important marine resource. The refuge was created by Executive Order 4467 in 1926; there has been a military presence on the atoll since 1934. It served as a refueling point for U.S. aircraft and submarines in World War II and as a base for airlift operations during the Korean War. The U.S. Air Force is the current host management agency and has operational control of the atoll. The infrastructure has grown to support the workforces necessary for various military missions; approximately 1,300 people live and work at Johnston Atoll. The military mission is almost complete, numerous closure and cleanup issues are being discussed, and the atoll will ultimately be returned to the U.S. Fish and Wildlife Service."
