ABSTRACT In Sweden, nature conservation management (NCM) is not applied to the extent needed to avoid negative impacts on biodiversity in voluntary set-asides and formal reserves. A limiting factor is the uncertainty of the costs for the operations caused by a lack of models for estimating costs and revenues in mechanized NCM. These may explain why some operations are highly profitable while others

Comparing single-wheel attachable tracks to chains and bare tires on skidders for mitigating soil disturbance during harvesting operations Int. J. For. Eng. (IF 1.9) Pub Date : 2022-09-07 Taylor Richmond, Rene H. Germain, Kristopher Brown, Russell Briggs, Stephen Stehman
ABSTRACT Tree-length harvesting with skidders is common in the Northeast US. Traditional rubber-tired skidders (with and without chains) make repeated passes over skid trails during a timber harvest. This traffic causes rutting and compaction which can lead to concentrated surface run-off and sediment delivery to streams. An innovation referred to as attachable tracks for wheeled logging equipment
