Coral Reefs: Rainforests of the SeaCoral Reefs: Rainforests of the Sea

Often called the ‘rainforests of the sea’ coral reefs are some of the most productive ecosystems on earth.

They provide support as habitat for fisheries, protect coastlines, offer medicines and generate tourism.

Reefs are fragile and susceptible to human impacts.

Globally they are in decline.

Global Marine Treasure

Rich Cultural HeritageRich Cultural Heritage

• In Hawaiian traditions, the NWHI are considered a sacred place, a region of primordial darkness from which life springs and spirits return after death

• Hawaiians inhabitated Nihoa for at least 700 years

• Numerous “wahi kupuna” (ancestral sites) provide evidence, along with songs, chants, stories

Remote But Not ImmuneRemote But Not Immune

Despite their remote location and absence of humans, the NWHI are still threatened.

• Up to 80 tons of marine debris accumulate each

Marine Debris in the NWHI:Marine Debris in the NWHI:Next StepsNext Steps

• Multi-agency clean up program is now in “Maintenance Mode” and led by NOAA Fisheries PIFSC and includes:– Targeted removal at high density areas (e.g. large

atolls)– Accumulation Rate Study

• U.S. Coast Guard removal efforts• Ghost Net project (R&D)/Census of Marine Debris• Outreach and Education focused on prevention

At-Sea Detection: Ghost Net ProjectAt-Sea Detection: Ghost Net Project

Role of the Future SanctuaryRole of the Future Sanctuary

Draft Management Plan includes an action plan focused on:

•Continued debris removal•Marine debris prevention & At-sea detection

Strategies include:•5-year removal and prevention plan•Research and development•Gain international cooperation•Outreach and Education

Multi-agency effort remains critical to success
