Thailand is situated in the tropical region of Southeast Asia just north of the equator from N5º 37´ to 20° 30´ and from E97º 20´ to 105º 39´. The country occupies an area of 513,115 km2 with about 25% tropical forests and 2,600 km of coastline. This area includes the Gulf of Thailand facing the South China Sea in the east and the Andaman Sea in the west covering a total area of 420,000 km2 which is rich in marine biodiversity and encompasses a highly productive fishery. Thailand is also well known for its natural wealth of white sandy beaches, beautiful coral reefs and rocky mountains all of which have become popular tourist attractions.
In the past decades, deforestation and environmental problems have led to tremendous loss of biodiversity and ecosystems. Nevertheless, Thailand still retains substantial bioresources and natural beauty to be enjoyed by casual visitors and naturalists as well as by professional biologists. Such is the case at Khanom – Mu Koh Thale Tai (or South Sea Islands) including Samui Island in the Gulf of Thailand. This area has beautiful scenery with natural treasures including some of the world’s most famous beaches and diving sites, and marvelous caves as well as a cultural diversity in folklore, making the South Sea Islands one of the most popular destinations for tourists.
Recognizing the prime importance of bioresources in the coastal area, BRT has launched an area-based research program on “Marine Biodiversity: Khanom - Mu Koh Thale Tai Initiative”. Mu Koh Thale Tai (or South Sea Islands) includes 5 major islands, i.e., Tan Is, Rap Is., Wang Nok Is., Wang Nai Is., and Mudsum Is. These areas belong to Khanom District, Nakhon Si Thammarat Province. This 3-year (2006-2008) initiative project was aimed to support research and training in marine biodiversity for young biologists and local communities as well as gather basic information on marine life occurring in these pristine habitats. The project’s management was based on a multidisciplinary approach among different groups of marine biologists. This project covered a general survey of marine life as well as an analysis of biotic and physical environments. The data collected will be useful for the long-term monitoring of the marine ecosystem in response to the effects of physical changes, e.g., a rise of sea temperature and water pollution.
This study has shown that “Khamon – Mu Koh Thale Tai” is rich in marine biodiversity and supports a variety of colorful fauna. A total of 719 species of marine life have been detected. These include rare and/or endangered species for Thailand, e.g., Pink Dolphins (i.e., Indo-Pacific Humpback Dolphins – Sousa chinensis), the Basket star (Euryle aspera) and the Gorgonian brittle star (Ophiopsammium semperi) as well as seagrass beds of only 0.1 km2 which provide food and shelter for juveniles of many marine organisms. More than 46 species of marine algae have been found including green calcareous marine algae (Halimeda macroloba). These algae could help reduce the rate of global warming by changing CO2 to calcium carbonate where it is deposited in the algae’s tissues. In addition, this study has revealed the unseen variety of marine organisms that live in harmony making the “Khanom – Mu Koh Thale Tai” one of the most valuable natural treasures in southern Thailand.
We can proudly say that the Khanom Marine Biodiversity Initiative Project has inspired and generated a new body of knowledge that has already appeared in scientific journals. Other publications such as books and magazines for general audiences have been made for public awareness of these valuable bioresources. Workshops and training for school students and local people have been conducted for appropriate management of Pink Dolphins and fireflies for ecotourism.
“Khanom Marine Biodiversity Initiative Project” was partially funded by BRT, the TOTAL Foundation of France and TOTAL E&P Thailand, the gas and oil business cooperative in the Gulf of Thailand. The project thus forms part of corporate social responsibility (CSR) of the private sectors in collaboration with the BRT and local communities in an effort to promote biodiversity conservation and sustainable development in Thailand.
This colorful and informative book on marine life and ecosystems will provide a brief introduction to unseen southern Thailand’s biological, cultural and historical wealth for nature lovers and tourists.
