The objective of this research was to know the degree of soil porosity caused by skidding of tractor caterpillar D7G in natural forest. The research showed that the soil porosity at conventional timber harvesting after skidding of deepness 0-5 cm, 10-15 cm and 25-30 cm was 59.8%; 59.9% dan 56.3% respectively. The bulk density at reduced impact timber harvesting after skidding of deepness 0-5 cm, 10-15 cm and 25-30 cm was 66.5 %; 63.4% dan 59.2%. respectively. This research indicated that the soil porosity at RITH was higher than conventional timber harvesting.
