Two damage schedules were developed in each study area: a loss schedule based on the scale of importance of
resource losses, and an activity schedule based on the scale of importance of impacting activities. The differences in
the resource characteristics and the economic importance of resources in the two coastal areas were properly
captured in the schedules. Although clear-cutting of the mangrove forests was considered to be the most important
loss in both study areas, the importance of activities causing this loss differed in each area. Shrimp farming involving
clear-cutting of mangroves was ranked first on the Ban Don Bay activity schedule, while hotel development involving
clear-cutting had the highest scale value on the Phangnga Bay schedule.
