to determine the effects that tree size has on the delivered wood cost, data was collected from existing literature on: average tree size (m3), average off road transport distance, volume per hectare (m3/ha), logging chance volume (m3) and average long-distance transport of wood in northern ontario. these variables were used to create three different modeled scenarios: current (extensive) practices, natural regeneration with thinning and intensive plantations. of the three scenarios the intensive plantation had the lowest cost of wood at $39.18/ m3. while the current (extensive) scenario was the highest at $49.19/m3. for each a sensitivity analysis was performed on each variable to determine the variable with the most significant impact on the delivered wood cost. through this it was found that the average long-distance transport distance played the most significant role and was capable of altering the final price by up to $12.04/m3. the average tree size was the second most significant contributing factor and was capable of altering the delivered wood cost by up to $3.82/m3. these results help define the effect intensive silvculture has on tree size and therefore on delivered wood cost.
