In 1997, FERIC studied a partial cutting operation in the Interior Cedar-Hemlock biogeoclimate zone, on a site west of Kitwanga, B.C. The operation used a Skylead C40 16000 skidder-mounted yarder and Mini-Maki II radio-controlled carriage in a standing skyline configuration and in single-and multi-span applications. The study provided information on productivity and costs for the harvesting system, impact on soil surface conditions, and damage to the residual stand. Productivity functions were derived to predict yarding productivity and costs over a range of operation conditions.
