Pouhala Marsh is the largest wetland habitat in Pearl Harbor. The marsh is vulnerable to flooding from the adjacent Kapakhi and Waikele streams, which flow into Pearl Harbor. The marsh is seriously degraded due to siltation, overgrown and invasive vegetation, waste disposal, illegal dumping, and from feral animals. It continues to support the endangered Hawaiian stilt and is a critical habitat for migratory shorebirds.
Objectives/Goals: Restoration of Pouhala Marsh to its historic seasonal and semipermanent marsh functions to provide feeding, loafing and nesting habitat for native Hawaiian water birds and migratory shorebirds and waterfowl through community outreach programs.
Methods Employed: • Feral animal control/removal
• Develop a trail system
• Develop a community-based wildlife monitoring program
• Storm drain stenciling
• Remove Pickleweed
• Remove debris
• Native plant replanting to stabilize stream bank
• Monitor wetland and shore bird populations
• Conduct bird surveys
• Conduct presentations/interpretive walks to educate community
• School related educational program to teach 3rd graders
Pollutants of Concern: Siltation, pathogens, heavy metals
Watershed: Kapakahi Watershed, island of Oahu
Size of Project: 70 acres
Affected Water Bodies: Pouhala Marsh
Deliverables: • Conceptual map of Pouhala Marsh
• Interpretive guide book
• Wetland/watershed curriculum
• Public service announcements (could be used as examples for other projects)
• Program evaluation to quantify awareness and attitude changes
• Web pages on Hawaii Nature Center web site
