United States Pacific Island Wildlife Refuges in the World
top of pageBackground: All of the following US Pacific island territories except Midway Atoll constitute the Pacific Remote Islands National Wildlife Refuge (NWR) Complex and as such are managed by the Fish and Wildlife Service of the US Department of the Interior. Midway Atoll NWR has been included in a Refuge Complex with the Hawaiian Islands NWR and also designated as part of Papahanaumokuakea Marine National Monument. These remote refuges are the most widespread collection of marine- and terrestrial-life protected areas on the planet under a single country's jurisdiction. They sustain many endemic species including corals, fish, shellfish, marine mammals, seabirds, water birds, land birds, insects, and vegetation not found elsewhere.

Net migration ratePopulation distributionUrbanizationMajor urban areasEnvironmentCurrent issues BakerIsland: no natural freshwater resources; feral cats, introduced in 1937 during a short-lived colonization effort, ravaged the avian population and were eradicated in 1965
Current issues
HowlandIsland: no natural freshwater resources; the island habitat has suffered from invasive exotic species; black rats, introduced in 1854, were eradicated by feral cats within a year of their introduction in 1937; the cats preyed on the bird population and were eliminated by 1985
Current issues
JohnstonAtoll: no natural freshwater resources; the seven decades under US military administration (1934-2004) left the atoll environmentally degraded and required large-scale remediation efforts; a swarm of Anoplolepis (crazy) ants invaded the island in 2010 damaging native wildlife; eradication has been largely, but not completely, successful
