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.
