Résumé
Between December 1993 and March 1994, FERIC monitored hand-falling and skyline-yarding operations in a 9.6-ha second-growth stand of Douglas-fir, western hemlock, and western redcedar in Coastal British Columbia. The study measured falling and skyline yarding productivities, identified factors influencing productivity, recorded extracted volumes by timber grades, and conducted post-harvest site assessments. Simple productivity prediction models were developed for falling only, falling and processing, and skyline yarding.

Résumé
In 1994, FERIC evaluated the performance of feller-bunchers, grapple skidders, roadside delimbers and slashers operating in overmature aspen stands in Central Alberta. The study aimed at providing the forest industry with information for projecting productivities and costs of harvesting overmature aspen stands. FERIC measured machine productivity in aspen stands of different characteristics, and fibre losses from excessive butt rot, upper stem defects, and conversion of tree-length stems into 2.6-m logs. The field data provided the input for determining operating cost and projected machine productivity as functions of tree size or skidding distance. This report also discusses the impact on cost of harvesting decaying stands.
