The research on corals in many areas found that coral reefs damaged by natural disasters Corals (such as bleached corals) can recover naturally. It has a natural recovery rate of approximately 1 - 11% per year (live coral cover increases by 1 - 11% per year), or an average of about 5% per year. However, there must be supporting factors which are water quality must be good and must not have any additional effects from humans. If the threat factors can be controlled and no natural disasters (e.g. coral bleaching It may take another 8 years for coral reefs to reach perfect levels. (Estimated with 60% or more of overall live coral cover). Recommendations that can be taken concretely to manage coral reefs' natural recovery are as follows:
​
1. Take control measures seriously. To provide marine tourism in an environmentally friendly way by training tour operators to follow the rules. This can lead to the Green Fins approach implemented by the Department of Marine Resources.
​
2. Take diving standards seriously, for example in fragile deep dive sites such as the pile of stones that are the source of coral Less experienced divers are not allowed to dive.
3. Install enough mooring buoys and strictly forbidden to leave anchors in coral reefs.
​
4. For and collect the underwater waste regularly for corals to recover normally.
​
5. There is clear zoning of utilization. Shallow water coral viewing sites (snorkelling) must determine the exact spot and the point where tourists stand on the ground.
​
6. Accelerating natural recovery is possible the National Park officials Actions should be taken as soon as coral fractures are observed coral repair. This can be learned by training with academics from the Department of Marine and Coastal Resources.
​
7. In the future, the standard of cruise vessels must be improved for vessels entering the park must be a vessel with a tank to collect waste from the toilet. Do not release waste into the parking area as a duck is torn because the wastewater from the toilet causes the disease to coral
​
8. Develop islands in the parking area to be garbage-free islands. Garbage must be brought back to shore on the mainland. It is strictly forbidden to throw it in the middle of the sea.
​
9. Manage surface waterlogging. by reducing waste emissions into water sources (control the number of tourists to suit the area) and use the natural aquatic plants on the island to help absorb nutrients and waste.
​
10. Build cooperation between agencies, such as conducting joint research in the National Park area. between the Department of National Parks Department of Marine and Coastal Resources, University, and Marine Science Society which the National Park Must facilitate seriously.
