Topic: Introduction
Background: 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. Baker Island: The US took possession of the island in 1857. Its guano deposits were mined by US and British companies during the second half of the 19th century. In 1935, a short-lived attempt at colonization began on this island but was disrupted by World War II and thereafter abandoned. The island was established as a NWR in 1974. Howland Island: Discovered by the US early in the 19th century, the uninhabited atoll was officially claimed by the US in 1857. Both US and British companies mined for guano deposits until about 1890. In 1935, a short-lived attempt at colonization began on this island, similar to the effort on nearby Baker Island, but was disrupted by World War II and thereafter abandoned. The famed American aviatrix Amelia EARHART disappeared while seeking out Howland Island as a refueling stop during her 1937 round-the-world flight; Earhart Light, a day beacon near the middle of the west coast, was named in her memory. The island was established as a NWR in 1974.

Jarvis Island: First discovered by the British in 1821, the uninhabited island was annexed by the US in 1858 but abandoned in 1879 after tons of guano had been removed. The UK annexed the island in 1889 but never carried out plans for further exploitation. The US occupied and reclaimed the island in 1935. It was abandoned in 1942 during World War II. The island was established as a NWR in 1974. Johnston Atoll: Both the US and the Kingdom of Hawaii annexed Johnston Atoll in 1858, but it was the US that mined the guano deposits until the late 1880s. Johnston and Sand Islands were designated wildlife refuges in 1926. The US Navy took over the atoll in 1934. Subsequently, the US Air Force assumed control in 1948. The site was used for high-altitude nuclear tests in the 1950s and 1960s. Until late in 2000 the atoll was maintained as a storage and disposal site for chemical weapons. Munitions destruction, cleanup, and closure of the facility were completed by May 2005. The Fish and Wildlife Service and the US Air Force are currently discussing future management options; in the interim, Johnston Atoll and the three-mile Naval Defensive Sea around it remain under the jurisdiction and administrative control of the US Air Force. Kingman Reef: The US annexed the reef in 1922. Its sheltered lagoon served as a way station for flying boats on Hawaii-to-American Samoa flights during the late 1930s. There are no terrestrial plants on the reef, which is frequently awash, but it does support abundant and diverse marine fauna and flora. In 2001, the waters surrounding the reef out to 12 nm were designated a NWR. Midway Islands: The US took formal possession of the islands in 1867. The laying of the transpacific cable, which passed through the islands, brought the first residents in 1903. Between 1935 and 1947, Midway was used as a refueling stop for transpacific flights. The US naval victory over a Japanese fleet off Midway in 1942 was one of the turning points of World War II. The islands continued to serve as a naval station until closed in 1993. Today the islands are a NWR and are the site of the world's largest Laysan albatross colony. Palmyra Atoll: The Kingdom of Hawaii claimed the atoll in 1862, and the US included it among the Hawaiian Islands when it annexed the archipelago in 1898. The Hawaii Statehood Act of 1959 did not include Palmyra Atoll, which is now partly privately owned by the Nature Conservancy with the rest owned by the Federal government and managed by the US Fish and Wildlife Service. These organizations are managing the atoll as a wildlife refuge. The lagoons and surrounding waters within the 12-nm US territorial seas were transferred to the US Fish and Wildlife Service and designated a NWR in January 2001.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.

Topic: Environment
Environment - current issues: Baker Island: no natural freshwater resources; feral cats, introduced in 1937 during a short-lived colonization effort, ravaged the avian population and were eradicated in 1965

Howland Island: 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

Jarvis Island: no natural freshwater resources; feral cats, introduced in the 1930s during a short-lived colonization venture, were not completely removed until 1990

Johnston Atoll: 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

Midway Islands:  many exotic species introduced, 75% of the roughly 200 plant species on the island are non-native; plastic pollution harms wildlife, via entanglement, ingestion, and toxic contamination Kingman Reef: none

Palmyra Atoll: black rats, believed to have been introduced to the atoll during the US military occupation of the 1940s, severely degraded the ecosystem outcompeting native species (seabirds, crabs); following a successful rat removal project in 2011, native flora and fauna have begun to recoverBaker Island: no natural freshwater resources; feral cats, introduced in 1937 during a short-lived colonization effort, ravaged the avian population and were eradicated in 1965
