Abstract:A transition-matrix forest growth model was developed and is described in this paper. The model was used to evaluate the Indonesian Selective Logging System (also called TPI), using the data obtained from a logging company located at East Kalimantan. Results indicated that the TPI system, under certain conditions, cannot sustain future harvests. Other alternative harvesting schemes were also evaluated by formulating a linear programming model for the harvest scheduling problem.
