Seub Nakhasathien tried to protect Huai Kha Kheang in every ways, but it was not enough to stop intrusions from those who seeked benefits. Protection and administration of a one-million-rai-forest with limited budget and human resources was very big responsibility and it constantly stressed him out. He found that the key problem of Huai Kha Kheang was poverty of those who lived around the forest. Poor villagers were used by rich and influential ones to work on illegal logging and hunting of wildlife in the area continuously.
In his view, one of ways to solve the problems were to create a buffer zone and moved villages to locate outside the zone, and at the same time developed the zone for villagers to make livings. However, Seub did not have enough power to materialize his idea, so he presented it to those with authorities. Unfortunately, no one listened, and Seub had to deal with the problems of Huai Kha Khaeng himself.
As Seub dedicated his life to conservation of forests, wildlife, and natural resources, his friends and colleagues agreed to carry on his will and dedication. Seub Nakhasathien Foundation was established with permission from the Ministry of Interior ten days after his royal-sponsored cremation, which was on September 18, 1990. Board members of the Foundation comprise those from various professionals who share the same idea with Seub. The Foundation was greatful to receive donation from Her Majesty the Queen in amount of 2,448,540 baht as starting funds, and from Her Royal Highness Princess Soamsavali in amount of 100,000 baht.
Besides this, the Foundation received donations from Seub’s relatives and friends. The Thai Government by former Prime Minister General Chartichai Choonhavan, took charge in fund raising for the Foundation. As a result, the starting funds of the Foundation was in total amount of 16.5 million baht. Only interest income of the starting funds is used for the Foundation’s activities. It can therefore be summarized that ideas of forest and wildlife conservations belongs to all walks of life; the Board Members are only those who help out in materializing the ideas.
