dc.description.abstractForest harvesting is an important intervention factor on the environment. Together with Indonesian Selection Cutting and Planting (TPTI)-system, they ensure the survival of the natural dipterocarps forest in Indonesia, by harvesting commercial trees with diameters above 50 cm and leaving behind minimal 25 young commercial and healthy trees per hectare distributed uniformly in the area. The research plots are located on forest concession areas of PT. Narkata Rimba and PT. Kiani Lestari, East Kalimantan, Indonesia. They consist of 4 permanent plots at PT. Narkata Rimba and 8 at PT. Kiani Lestari. The size of each plots is 100 x 100 m. The research began in 1992. The remeasurements are conducted annually. The observations and analysis had been made on the effects of forest harvesting with TPTIsystem on the residual stand of dipterocarps forest and it's relation to the damages, structure and composition dynamic changes, natality, mortality, growth after wood harvesting, and the sustainability of the logged over forest. The research indicates that the levels of residual stand damages (2845%) correlate to the logging intensity and the incident of damages to small trees is greater (ca. 80%). Most of the damage trees are heavy injured (ca. 85%). Harvesting cause decreases of biodiversity (lost of some species) but do not change the structure of the stand. It takes about 14 years after wood harvesting, that the biodiversity will be as before.id
