If national parks are America’s best idea, then national wildlife refuges are America’s best kept secret. Wildlife refuges conserve America’s fish, wildlife and plants and their habitats – and often provide amazing recreation opportunities. Johnston Atoll National Wildlife Refuge is one of 7 national wildlife refuges at the heart of the Pacific Remote Islands Marine National Monument, one of the largest marine conservation areas in the world. While Johnston Atoll is hard to get to – it may be the most isolated atoll in the world – the refuge is an oasis for coral reef and bird life. Several dozen coral species and hundreds of different fish species reside in Johnston’s offshore reefs, and onshore plants provide essential nesting habitat and cover for seabirds from the extreme heat and wind.
