CONCLUSIONS

The coastal vulnerability index (CVI) provides insight into the relative potential of coastal change due to future sea-level rise. The maps and data presented here can be viewed in at least two ways:

1) as an example of where physical changes are most likely to occur as sea-level rises; and

2) as a planning tool for the Fire Island National Seashore as well as other parts of the Long Island Atlantic coast.

As ranked in this study, geomorphology and shoreline change are the most important variables in determining the CVI for Fire Island. Wave height, tide range, coastal slope, and sea-level rise do not contribute to the spatial variability in the coastal vulnerability index.

FIIS preserves a dynamic natural environment, which must be understood in order to be managed properly. The CVI is one way that a park can assess objectively the natural factors that contribute to the evolution of the coastal zone, and thus how the park may evolve in the future.
