Helping the Refuge

Kalaeloa Unit Outplanting Endangered Akoko

Kapolei High School student volunteers outplanted 34 specimens of the endangered plant akoko on small prepared sites on the unit. Akoko is an imperiled species of dry coastal coralline habitat. This coastal habitat has been very heavily developed and fragmented. Only 13 plants from previous outplantings are known on the refuge and probably fewer than 50 exist anywhere in the wild.

Restoration on the Refuge

  • Restoring Anchialine Pool

    Kapolei High School students under the guidance of ES Biologist Lorena Wada and refuge staff have completed the restoration of an anchialine pool. The students helped operate small water pumps, removed earthen debris from the pool, washed and searched the spoil for paleontological avian bones.

  • Removing Mangrove Trees

    Volunteers from the Hawai‘i Nature Center and military personnel from Joint Base Pearl Harbor-Hickam spent a muddy Saturday morning pulling and cutting young, exotic red mangrove trees from the mudflats along 600 feet of shoreline of the Waiawa Refuge Unit. These restored intertidal mudflats receive continuous use by endangered Hawaiian stilts and migratory shorebirds.
