Abstract

ABSTRACT
Openness of forest land due to timber harvesting is a loss of forest soil surface protection caused by logging,
skidding, making forest road network, timber stockpiling, base camp and so forth. The aim of this research is to
calculate the percentage of forest land clearing due to temporary timber harvesting (tree felling, skidding, skid trail
construction, TPn) and permanent nature (making of main and branch road network). The research was conducted at
IUPHHK-HA PT Indexim Utama Central Kalimantan. The results show that the percentage of forest land clearing due
to timber harvesting is much higher (19.54%) than that of permanent (4.55%). Deforestation and main road making
activities contributed the most to the percentage of temporary and permanent land clearing respectively by 10.66%
and 3.94%.
Keywords: Temporary and permanent, natural forest, forest land clearance, timber harvesting.
