Which of the following is considered a 'high-lead' logging method?
Answer: Logs suspended from a tall spar tree or tower and yarded to a landing
High-lead logging uses a tall spar tree or steel tower with cables to lift the front end of logs off the ground and pull them to a landing.
What is the main environmental concern associated with poorly located skid trails?
Answer: Increased soil erosion and stream sedimentation
Improperly located skid trails on steep slopes can cause significant soil erosion that delivers sediment to streams, harming aquatic habitats.
A 'forwarder' differs from a skidder in that it:
Answer: Carries logs on a bunk completely off the ground
A forwarder lifts logs onto a bunk and carries them clear of the ground, reducing soil compaction and bark damage compared to skidding.
In timber harvesting, 'directional felling' refers to:
Answer: Intentionally falling a tree in a predetermined direction to minimize damage
Directional felling uses notching and back-cutting techniques to guide a tree's fall in a specific direction, protecting residual trees and reducing slash.
What does 'utilization standard' mean in a timber sale contract?
Answer: Minimum log diameter and length a purchaser must harvest
Utilization standards specify the minimum size (diameter, length) of wood products that must be removed from the sale area to ensure efficient use of the timber resource.
Which of the following practices helps reduce soil compaction during mechanized logging?
Answer: Restricting heavy equipment to designated trails
Confining equipment movement to designated skid trails limits compaction to a small percentage of the harvest area, protecting the majority of forest soil.
