Abstract
The uneven-aged mixed dipterocarp forcsts of Southeast Asia arc managcd using mainly the minimum diameter cutting limit approach. In many cases a fixed cutting limit is applied for example the Sabah Modified Malayan Uniform System MMUS and the Indonesian Tebang Pilih Tanam Indonesia TPTI while in Peninsular Malaysia a variable cutting limit is practised under the Selective Management System SMS. Uneven-aged mixed dipterocarp forests vary in stocking size structure and species composition. In productive stands with high proportions of large-sized trees the application of fixed cutting limits will likely cause excessive damage to the residual stands with removal of large number of large-sized individuals. This paper describes a method to design desired stand conditions in uneven-aged mixed dipterocarp forest through the manipulation of stocking density and allocation of residual growing stock among size structure and species composition. These factors are important determinants for maintaining greater stand productivity and can be manipulated directly by foresters. The proposed method uses the following information: 1 stock inventory data 2 maximum stand density 3 allocation of growing stock by size class and species group and 4 damage factors in relation to harvesting intensity. This information is integrated into a stand simulator AGS-l developed at the Forest Research Institute Malaysia FRIM to design the stand conditions desired.
