Transporting the forest residues located in slash piles out of the woods requires vehicles and equipment to roll and vibrate over bare ground.  This activity can cause soil compaction and disturbance, which can lead to adverse soil erosion and limit plant growth.

Numerous studies and harvesting policies have been initiated to lessen the impact of soil compaction …more

Typically when trees are harvested for lumber and pulp, the limbs and branches (commonly termed “forest residuals”) are left on the forest floor or collected in slash piles and burned. If these forest residuals were used instead to produce products such as biojet fuel, what effect would that have on our environment and how can we manage the resource …more
