The research purpose was to determine the process or production activities, the log stock damage level and the log stock conditions as the Intsia spp. production impacts in IUPHHK PT Megapura Mambramo Bangun West Papua. The forestry activities carried out by IUPHHK PT Megapura Mambramo Bangun refers to Indonesian planting selective cutting system (TPTI) and limited to Intsia spp. with production in RKT 2011 (total area 1300 ha) was 2538 trees and 68477.30m³ volume, but based research results obtained with 210 rods by 2497.55m³ volume (sampling area 120 ha in wide). The forest damage occurred in IUPHHK PT Megapura Mambramo Bangun as the Intsia spp. production included the trees felling area covering to 7.79 ha, the liana cleaning area covering to 11.40 ha, the skidding trails making area to 7.39 ha and the branch or main road construction area along with 10.081 km by 22.16% damage intensity. The greatest log stock damage level caused by skidding activity compared with the cutting which included seedlings level after cutting was to 50.04% and skidding was to 77.76%, the stake level after cutting was to 49.62% and the skidding was to 72.35%, the pole after logging was to 22.66% and skidding was to 87.75% and the trees level after logging of 13.38% and skidding of 77.82%.
