Kerusakan Tingkat Tiang dan Pohon Jenis Komersial Akibat Penebangan Intensitas Rendah di IUPHHK-HA PT. INHUTANI II Malinau

Abstract

Natural forest harvesting with Indonesian Selective Cutting and Planting (TPTI) can cause damage to the residual stand. Commercial species are important because they are used for production purposes. Damage to commercial types will reduce the number of trees which will harvested in the next cutting cycle. So far, research on damage to the residual stand with low intensity felling has not been widely studied. This study aims to calculate damage and the type of damage to commercial trees with diameter ≥ 10 cm due low-intensity felling. Measurement of the level damage poles and trees of commercial species are done on variable circular plots. The average area of the plot is 2.34 ha. The results showed that felling trees 0.43/ha can caused damages of 3 poles/ha and 3 trees/ha. Type of damage to the pole and tree was dominated by broken tree canopy
