Restoration Activities
Case: Chevron, HI
Briefly, the restoration activities consisted of:
Enhancement of Pouhala Marsh. This area, a remnant fish pond and coastal marsh, is located in Pearl Harbor's West Loch. This marsh is the largest remaining wetland habitat in Pearl Harbor, serving as habitat for native endangered waterbirds and several species of migratory shorebirds. The trustees restored 8 acres of degraded and partially filled areas of the marsh. This project created a more open water habitat adjacent to the shoreline and provided for the enhancement and maintenance endowment of the marsh. The U.S. Fish and Wildlife Service (FWS) led this effort on behalf of the trustees and in cooperation with Ducks Unlimited, Inc., the state of Hawaii, and the city and county of Honolulu.
Waiawa Unit Mangrove Removal Project. This project was designed
to create shallow, open water habitat by removing 4 acres of introduced red
mangroves. Removal was intended to benefit intertidal and shallow subtidal
species (i.e., small invertebrates, polychaetes); species feeding on organisms
in those habitats, such as the Hawaiian stilt, shorebirds, and wading birds;
and water column species such as the juvenile Hawaiian anchovy and shallow
water finfish. The red mangrove is an exotic plant species in Hawaii that
replaces and alters habitat essential to a number of native estuarine species,
and it displaces foraging habitat for waterbirds and shorebirds. The U.S. Fish
and Wildlife Service at the Pearl Harbor National Wildlife Refuge, Waiawa Unit,
is leading this effort on behalf of the trustees.
Shoreline protection system. This project replaced the existing, inadequate shoreline protection system at the U.S.S.
Arizona Memorial Visitor Center with a new permanent riprap system to prevent erosion. The area encompassed the shoreline from the visitor center dock to the ferry landing adjacent to the visitor center, approximately 600 feet. The National Park Service managed this project on behalf of the trustees. Chevron completed the riprap repair to the shoreline.
Visitor center boat dock. This project supplemented an ongoing project for the design, removal, and replacement of the rapidly deteriorating shoreside boat dock at the U.S.S.
Arizona Memorial Visitor Center, and was a preferred alternative to address the lost visitor services. To reach the memorial, which straddles the sunken remains of the U.S.S. Arizona,
visitors are transported on U.S. Navy boats from this boat dock.
