James Campbell National Wildlife Refuge

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, koloa maoli, ʻalae ʻula, and āeʻo and many migratory seabirds, endangered and native plant species, and the endangered Hawaiian monk seal and green sea turtle. It also provides increased wildlife-dependent public uses and flood control within the refuge and the local community.
