ABSTRACT
Tree felling and conversion in Pakistan is done by hand tools; axes and
saws. These, besides being primitive are inefficient, thus causing low labour
productivity, and delays in exploitation and subsequent regeneration operations
in the forests. Introduction of power chain saws for felling and conversion of trees
is essential to speed up timber harvesting operations so that enough time is
available for regeneration work as well as to increase the labour productivity. It
has been observed in many countries that power chain saws are more than three
times efficient in timber production during felling and conversion than hand tools
(Pearce and Stenzel, 1972). Hence their use is quite common in the developed
countries. However, considerable research is needed to determine the suitability
and economics of working of these tools in different countries and forests in view
of the varied socio-economic conditions prevailing in them.
