Malden Island importance as a protected area for breeding seabirds. The island is designated as the "Malden Island Wildlife Sanctuary". In 2014 the Kiribati government established a fishing exclusion zone around each of the southern Line Islands (Caroline (commonly called Millennium), Flint, Vostok, Malden, and Starbuck). Malden Island is located south of the equator, south of Honolulu, Hawaii, and more than west of the coast of South America. The nearest land is uninhabited Starbuck Island, to the southwest. The closest inhabited place is Tongareva (Penrhyn Island), to the southwest. The nearest airport is on Kiritimati (Christmas Island), to the northwest. Other nearby
Kiritimati otherwise leaving them alone to hunt rats may well be the optimal solution. The 1982/83 "mega-El Niño" devastated seabird populations on Kiritimati. In some species, mortality rose to 90% and breeding success dropped to zero during that time. In general, El Niño conditions will cause seabird populations to drop, taking several years to recover at the present density of predators. Global warming impact on Kiritimati is thus unpredictable. El Niño events seem to become shorter but more frequent in a warmer climate. Much of the island's infrastructure and habitation, with the notable exception of the airport area, is located to
