The CVI values calculated for Guam range from 5.0 to 10.0. The mean CVI value is 7.10; the mode is 10.0 and the median is 6.12. The standard deviation is 1.88. The 25th, 50th, and 75th percentiles are 5.5, 7.0 and 8.75, respectively.

Figure 11 shows a map of the coastal vulnerability index for War in the Pacific NHP. The CVI scores are divided into low, moderate, high, and very high-vulnerability categories based on the quartile ranges and visual inspection of the data. CVI values below 5.5 are assigned to the low vulnerability category. Values from 5.5 to 7.0 are considered moderate vulnerability. High-vulnerability

values lie between 7.01 and 8.75. CVI values above 8.75 are classified as very high vulnerability. Figure 12 shows the percentage of War in the Pacific NHP shoreline in each vulnerability category. Over 11 km (7 miles) of park shoreline is evaluated, and of this total, twenty-six percent of the mapped shoreline is classified as being at very high vulnerability due to future sea-level rise. Twenty percent is classified as high vulnerability, twenty percent as moderate vulnerability, and thirty-four percent as low vulnerability.
