The Orang Asli ethnic group reside in the forest in the Sankalakiri Mountain Range in Yala and Narathiwat provinces. The Malay Thais in the three southern provinces call the mountain range “Bukit Buecha” in their Malay dialect. The study areas were in the Banglang National Park, Halabala Wildlife Sanctuary, and some community forests. The ethnic group is strongly connected to their environment and exploits basic and modern technologies for their survival. They have been able to transition themselves from a hunter-gatherer society to a modern world in several dimensions. The abundance of forest resources has dwindled after the construction of the Bang Lang Dam, creating a huge reservoir that inundated a large swath of the forest. Additionally, a road was cut through the forest and a waterway enables outsides to access to their communities. Despite the ecological changes, some of them have been able to adapt to the water ecological system. They have found new settlements, which have led to nomadic lifestyle in small islands, and even speed boats are being used for services as a new way of earning a living.
