A number of large Dipterocarpus trees known as Ton Yang have blackened holes cut out of their trunks. Local people tap this kind of tree for their resin or creosote, dark-brown oily tar. Creosote is used for caulking wooden boats and used for certain varnishes. To collect this tar the villager has to make a hole in the tree trunk and a fire is lit inside to stimulate the resin flow. After a few minutes, the fire is put out and the hole covered with a palm leaf. The collector returns in two or three days to collect the accumulated oily resin. One slot should be dug in the tree and burning can be done once a month, otherwise the tree may die.
Wild tree lizards are commonly found in this forest. Their color looks similar to the tree bark, thus the visitors who do not take look carefully may miss them.
