Costs differ with slope classes. The values represent costs for slope class "flat" (< 15%). Costs for skidding are supposed to rise by 25% in slope class "medium" and 100% at "steep" slopes compared to costs listed here. These differences are due to special equipment (like cable way) needed for timber extraction at steep slopes. Costs for thinning rise only in the "steep" class by 15% on average due to the need for special machines. Harvest costs (motor manual with chain saw) are assumed to be constant over slope classes |
