In today’s world, timber harvesting is conducted using efficient machinery that has a reduced impact on the land. Modern harvesting techniques have dramatically reduced or eliminated dangerous conditions, wasted wood, and excessive soil disturbance. Trees are harvested with the least amount of impact, including aerial lifting to minimize ground disturbance, cable systems for steep slopes, and mechanical, ground-based harvesting. Modern harvesting techniques also incorporate protections for wildlife, plants, archaeological sites, and other environmental attributes of the forest.
