Exploitation Factor in Limited Production Forest in Licensed NaturalForestConcessionary PT. Kemakmuran Berkah Timber

In timber harvesting, exploitation factor is implemented as the one parameters to determine the allocated annual production at the natural production forest. Currently, the value of exploitation factor as stipulated by the Ministry of Forestry that applies to all conditions of natural production forest exhibits large varying-topographies and in operation tends to be heavier than tose at either the fixed productionforest or convertible production forest. This situation brought about a significant difference in the exploitation factors (EF) during the timber harvesting. In average the value of EF at the Licensed Natural Forest Concessionary PT Kemakmuran Berkah Timber reached 0.92, while the EF at flat topograply (0-8') was 0.9 3; at moderately sloping (9-15'), rather steep (16-25'), and steep topographies (2640') were all similar, i.e. 0.92.
