The Forest Engineering Research Institute of Canada (FERIC) estimated the costs of harvesting, comminuting, and transporting pine trees killed by the mountain pine beetle in the central Interior of British Columbia. Costs were based on computer models that used three different harvesting systems depending on the ratio of sawlogs to fuelwood in the stand. For stands with less than 50% fuelwood, the existing roadside harvesting system was used to harvest sawlogs and generate roadside residuals, followed by a separate operation to comminute and transport the feedstock. This system had the lowest cost. Stands with 50-95% fuelwood were costed using a satellite sortyard. This system was best suited to sort the sawlogs from stands containing predominantly fuelwood, but it also had the highest cost.
