Figure 13. Relative Coastal Vulnerability ranking for National Park of American Samoa. The colored shoreline represents the relative coastal vulnerability index (CVI) determined from the six variables. The very high vulnerability shoreline is located along unconsolidated segments of shoreline, within embayments, and where wide fringing reef is present. High vulnerability shoreline is present on Ta'u and along the north coast of Ofu and Olosega where narrow fringing reef is present. Low vulnerability shoreline is primarily located along rock cliff coastline where coral is absent.
