Evaluation of Salvage Logging Productivity and Costs in the Sensitive Forests of Bulgaria

Steep terrain harvesting can only be implemented by a limited set of operational alternatives; therefore, it is important to efficient in such conditions, order avoid incurring high costs. Harvesting abiotically-disturbed forests (salvage harvests caused wet snow), which becoming common these days, significantly impact the efficiency extraction operations. This study was evaluate performance truck-mounted uphill cable yarding operations salvage logging deployed coniferous stands. A time used estimate productivity and costs, predictive models were developed relate consumption relevant factors, including degree wood damage. The average conditions characterized an distance 101 m lateral 18 m, resulting rate 20.1 m3 h−1. In response different kind delays, decreased 12.8 Under prevailing accounted for 32% gross work cycle time, 50% delay-free machine. Decreasing increasing payload volume maximum capacity machine would eventually lead close 30 per SMH (scheduled hour). calculation costs showed that labor (35.7%) slightly higher than fixed (32.9%), twice as compared variable (17.7%). remote control carriage, mechanical slack-pulling mechanisms, radio-controlled chokers are just some improvements have led increments efficiency.
