Pearl Harbor National Wildlife Refuge, National wildlife refuge in Honolulu County, United States.
Pearl Harbor National Wildlife Refuge is a protected area in Honolulu County consisting of three separate units: Honouliuli, Waiawa, and Kalaeloa. The refuge contains wetlands, brackish ponds, and coastal shrubland spread across these distinct areas.
The refuge was established in 1972 as an environmental compensation measure following construction of the Honolulu International Airport Reef Runway project. This action responded directly to the impact that airport development had on the local environment.
The refuge protects Hawaiian native species such as the aeʻo waterbird, night-blooming Maiapilo plants, and ʻōpaeʻula shrimp in their natural habitats. These organisms hold deep meaning in Hawaii's natural heritage and represent the uniqueness of island wildlife.
Visitors can observe wildlife from the Betty Bliss Memorial Overlook, which is open throughout the year. For full access to the refuge, you need authorization from management, making the overlook the best spot for viewing from the ground.
The Kalaeloa Unit contains rare anchialine pools, water bodies with underground connections to the ocean that support specialized Hawaiian aquatic life. These waters exist in only a few places on Earth and create one-of-a-kind habitats.
