all the management approaches identified in the plan, the zoning plan is the one in urgent need of review because of the declining condition of reefs and increasing demand of visitors. Recently, Surin has applied a clarified mooring system to better identify use areas. The mooring system has the additional benefit of limiting the number of visitors in each area at any one time. Areas with higher conservation values have fewer buoys than recreation areas. Sites with mooring buoys have shown improvement in live coral coverage. However, since this research covers only one year, additional studies on the benefit of the mooring system, and the perception and behaviour of visitors on management approaches are recommended.
