Machine traffic can cause severe and long-lasting soil disturbances that harm forest health and productivity. Restricting machine traffic to a planned extraction network helps mitigate these impacts.
Introduction
Restricting machine traffic to an existing extraction network means concentrating harvesting machinery on planned skid trails or strip roads rather than driving across the entire stand. This approach reduces the area exposed to soil compaction, rutting and other physical disturbances that can persist for decades and impair soil structure, water infiltration, root growth and long-term forest productivity. Careful planning of extraction trails is one of the most effective measures for minimizing environmental impacts while maintaining efficient harvesting operations. Successful implementation depends on using designated extraction trails, limiting unnecessary machine passes, considering slope, soil type and soil moisture when planning operations, and avoiding traffic during periods when soils are particularly vulnerable to damage.
