The Feasibility of Harvesting and Extraction of Logging Residues in Sabah

Effective harvesting and utilisation of log and logging residues are important, in achieving the sustainable forest management and to maximize the government revenue, in the light of declining supply of conventional logs. The aim of this study was to evaluate the feasibility of harvesting and ex...
