The late Mr Nakhasathien worked as a forest researcher at the Wildlife Sanctuary in Thailand from 1975 to 1979. In 1983, as Chief of the Wildlife Rescue Project he worked unrelentingly to rescue drowning wildlife while also fighting against illegal poachers. In 1987 he campaigned against the construction of the Nam Choan, a 580 megawatt dam planned for the Thung Yai Naresuan Wildlife Sanctuary. In 1989, as chief of a Wildlife Sanctuary, he succeeded in saving 6,000 square kilometres of land from exploitation. Nakhasathen took his own life on September 1 1990 following the shooting and death of two of his rangers by poachers and renewed frustrations encountered in his struggle to protect the environment.
