James Campbell National Wildlife Refuge is a National Wildlife Refuge on the island of Oʻahu, Hawaii. It was established in 1976, to permanently protect an ecologically-intact unit and to provide habitat for native and migratory fauna and native flora. It established critical habitat for Hawaii's four endangered waterbirds, the ʻalae kea (Hawaiian coot, Fulica alai), koloa maoli (Hawaiian duck, Anas wyvilliana), ʻalae ʻula (Hawaiian gallinule, Gallinula chloropus sandvicensis), and āeʻo (Hawaiian stilt, Himantopus mexicanus knudseni) and many migratory seabirds, endangered and native plant species, and the endangered Hawaiian monk seal and green sea turtle.
