Information on the long-term coral reef status of the country It began to be reported during the years 1995-2015 Data was obtained from surveys using the Manta tow technique, which is a survey of coral reef status covering a large area Since 2016, coral reef status reporting has shifted to data from Line Intercept Transect surveys, which are detailed surveys to provide in-depth academic data that can be used to compare periodic data long in the original area The data were collected only in areas representing certain coral reefs by surveying coral reefs until all areas in every province It has a cycle of about 4-6 years.

Later in 2018, the meeting of the National Marine and Coastal Resources Policy and Planning Committee Resolution for the Department of Marine and Coastal Resources and the Department of National Parks, Wildlife and Plant Conservation jointly prepare plans and guidelines for surveys and monitoring and assessment of the status of coral reefs in Thailand by jointly establishing 445 stations to monitor the status of coral resources of the country by the Department of Marine and Coastal Resources Conducted surveys in the area outside the park's boundaries of 193 stations, and the Department of National Parks, Wildlife and Plant Conservation conducted surveys in the areas responsible for 252 stations in order to reduce the problem of personnel limitations, and to obtain data around the survey annually Instead of having to take 4 years, the latest number of survey stations in 2021, the Department of Marine and Coastal Resources Conducted surveys in the area outside the park's boundaries with 168 stations, and the Department of National Parks, Wildlife and Plant Conservation conducted surveys in the areas responsible for 189 stations, totaling 357 stations.

Surveys from 1995 to 1998 found that Thailand had coral reefs in good condition. moderately complete and damage in similar proportions, at 31.5%, 32.1 and 36.4%, respectively, as well as the survey during 2006 - 2008, which found that coral reefs have not changed much. The coral reef area is in good condition. slightly increased from the original to 34.0%. Reefs that were moderately intact The number was reduced to 28.9 percent, while coral reefs were damaged. There was a slight increase of 37.1%. Data from the 2011–2015 Coral Reef Survey showed a significant increase in damaged reef areas. This increased to 78.4%, while coral reefs were in good condition and coral reefs were moderately intact. decreased to only 5.7 percent and 15.9 percent, respectively. The main cause of coral reef degradation during this period was the coral bleaching that occurred across Thai waters in 2010, Most reefs were severely affected. Causing the condition of most coral reefs to be damaged, such as coral reefs in the eastern Gulf of Thailand and the western Gulf of Thailand. On average, 45 - 50 and 70 percent of corals survived after coral bleaching, while on coral reefs in the North Andaman Sea In the southern Andaman Sea (Trang and Satun provinces) corals survived after bleaching on average 60%. Human utilization activities are also contributing to increased coral reef degradation. Or slower recovery from damage from various causes by marine tourism activities and coastal development to support tourism activities. Including coastal sediments is a major contributor to the degradation of many coral reefs. Causing the status of coral reefs during the year 2011 – 2015, most of them were in a damaged state.

The 2016–2017 survey was a continuation of changes in survey methods and coral reef surveys. from the original that had to be re-explored Using a 4-year survey to divide the survey area between the Department of Marine and Coastal Resources and the Department of National Parks. wild animals and plants which must survey all stations nationwide within 1 year, but with a lack of manpower and budget As a result, in some areas, the same data from previous surveys since 2015 are required to cover enough coral reef areas to represent the state of the coral reefs of each province. However, coral reefs are recovering. The coral reefs are in good condition. and coral reefs with moderate integrity increased from the original to 11.5% and 27.5%, respectively. decreased to 61.0 percent

The 2018–2019 survey was a period in which a detailed survey of coral reef status was conducted simultaneously at all stations across the country by cooperation between the Department of Marine and Coastal Resources and the Department of National Parks Wildlife and Plant Species, for the first time in 2018 and continuing in 2019, coral reefs have returned to a similar status to the 1995-1998 period.

A recent survey in the period 2020-2021 found that coral reefs were similar in status to coral reef status during 2018-2019, with a slight improvement in trend. It was found that most of the coral reefs were in moderate to very good condition. which had a similar proportion during the years 2020-2021, found that the status was equally good and moderately intact, which was 38%. equal to 36 and 33 percent, respectively.
