If not done properly performed, harvest operations can damage forest soils by compaction, rutting, erosion and nutrient loss. Forest harvesting equipment moving across a cutblock may directly or indirectly impact water quality and future tree growth. To maintain soil health during harvesting, field supervisors must know when there is a risk of damage, and understand how equipment operations affect the soil. This guide was created to provide practical advice for field supervisors to minimize soil and site damage during harvesting operations.
