This study compares the destruction of advance regeneration when three different skidder types are used: cable, grapple and clambunk, under comparable stand and terrain conditions. Six study blocks located on Domtar Inc.'s logging operations at Mistassini, Qc, were assessed before and after harvesting. Results on pre- and post-harvest regeneration levels, machine productivity and degree of soil disturbance are presented.
