Forest preservation techniques in the Urals

Logging is essential to provide society with fuel, building materials, furniture and myriad other needs. At the same time, the ecosystem must be conserved so that the resources are sustainable. This paper considers the impact of forestry activities on forest vegetation and soil indicators: mean height, mean diameter, mean age, tree stock, plant density, soil density, thickness and porosity. The authors analyse the effect of five types of forest machinery operating three extraction (skidding) procedures: butt-first, top-end first, and untrimmed trees. Butt-first skidding using the Amkodor 2242B wheeled tractor was found to have a minimal effect on plant valuation indices; the least damage to soil attributes was inflicted by crawler tractors skidding untrimmed trees. © 2022 Informa UK Limited, trading as Taylor & Francis Group
