Abstract

ABSTRACT A study was carried out in Changa Manga forest plantation in 1984-85 for the comparison of conventional and improved tools in timber harvesting on the basis of technical labour productivity under an equal and maximum work stress. Result of the study reveal that the technical labour productivity of conventional and improved tools at maximum work stress is 0.47 and 0.61m3 of timber and firewood per man hour respectively. Improved tools were found to have (30%) higher productivity than conventional tools in tree felling and conversion and therefore were recommended for introduction in timber harvesting in Pakistan.
