1. PIFSC External Review, June 24, 2008 Integrated Coral Reef Ecosystem Assessments in the U.S-affiliated Pacific Islands

2. Vision Statement CRED leads an integrated, interdisciplinary, ecosystem-based program of research, mapping, and long-term monitoring of coral reef ecosystems of the U.S.-affiliated Pacific Islands to promote conservation and management through innovative and collaborative science of the highest integrity.

3. Threats Climate change Climate change Ocean warming – coral bleaching and disease Ocean warming – coral bleaching and disease Ocean acidification – calcification rates, biodiversity shifts Ocean acidification – calcification rates, biodiversity shifts Sea-level rise – drowning reefs and coastal infrastructure? Sea-level rise – drowning reefs and coastal infrastructure? Storm tracks and intensities Storm tracks and intensities Ocean circulation – larval transport/recruitment Ocean circulation – larval transport/recruitment Local Threats Overfishing - trophic and ecosystem shifts Overfishing - trophic and ecosystem shifts Pollution and marine debris – habitat degradation Pollution and marine debris – habitat degradation Coastal development and sedimentation – habitat degradation Coastal development and sedimentation – habitat degradation Invasive species – ecosystem shifts Invasive species – ecosystem shifts Recreational overuse – trophic and ecosystem shifts Recreational overuse – trophic and ecosystem shifts Global threats significantly impact local/regional ecosystems Local management requires knowledge of regional and global processes and threats

6. Corals Mean coral cover MHI (9.0 ± 2.3%) comparable to NWHI (10.4 ± 2.0%) Other corals Montipora Acropora Pocillopora P. compressa Porites Distribution, composition, abundance (density/cover), and size of corals over time

7. Coral & Algal Disease Distribution, type, and prevalence of disease by coral and algal species over time BLE: Bleaching SGA: Skeletal growth anomalies WSY: Acute tissue loss TLS: Subacute tissue loss TRE: Trematodiasis HYP: Hyper-pigmented irritations EFI: Endolithic fungal infection OTH: Other BLE: Bleaching SGA: Skeletal growth anomalies WSY: Acute tissue loss TLS: Subacute tissue loss TRE: Trematodiasis HYP: Hyper-pigmented irritations EFI: Endolithic fungal infection OTH: Other

8. Algae Algal composition, both in the NWHI and more broadly across the Pacific region, shows distinct biogeographic patterns. Note different regions of the NWHI: North, Mid, South. From Vroom & Page (2006) From Schils and Vroom (in review)
