Which equipment is listed as types of extraction in forestry?

• A. Horse, forwarder, skidder, cable system
• B. Bulldozer and crane
• C. Motor grader and dozer
• D. Sky crane and helicopter

Answer: (A)

Extraction in forestry means moving felled logs from the stump to a landing or road, using gear that fits different terrain and minimizes soil impact. The combination of horse, forwarder, skidder, and cable system covers the main, traditional extraction methods: a horse provides animal-powered hauling in difficult or sensitive terrain; a skidder drags logs along the ground to a ramp or road; a forwarder carries whole logs off the ground, reducing soil disturbance on uneven ground; and a cable system uses yarding lines and winches to move logs from remote areas to a collection point. The other options mix equipment used for site prep, road work, or aerial methods, rather than representing the standard extraction approaches shown here.
