INHUTANI II in Pulau Laut, South Kalimantan was carried out.The results of the investigation lead to the following conclusions:1.

It is found that the crown of 11 trees/ha were damaged, consisted of 9 tree crowns were damaged partially and 2 tree crowns were damaged totally.2. Steeper terrains caused larger decrease of crown closure of the trees. On the slope of 0-15%, 25-45% and 45% and above, the crown closure reductions were 61%, 76% and 80%, respectively
