Which of the following describes harvest strategies?

• A. felling, extraction, harvest strategies
• B. clearcutting, seed-tree method, shelterwood method, thinning/release cutting, low thinning, crown thinning, selection thinning, mechanical/row thinning, salvage thinning
• C. manual, mechanized
• D. horse, forwarder, skidder, cable system

Answer: (B)

Harvest strategies are the planned approaches used to harvest timber in a stand, guiding how much is removed, when, and how regeneration and site conditions are managed. The best choice lists a range of cutting and thinning methods—clearcutting, seed-tree and shelterwood, plus various thinning and salvage options—which together define the different harvesting strategies used to meet regeneration goals, stand structure, and site conditions. For example, clearcutting creates a full-sun environment for species that require it, while shelterwood and seed-tree methods provide a seed source and protection during regeneration; thinning treatments reduce competition and shape future growth, with distinctions like low thinning, crown thinning, and selection thinning. Salvage thinning addresses damaged or stressed stands, and mechanical or row thinning describes a method of spacing and removing trees. The other options describe how work is done or what equipment is used, rather than the strategic mix of harvesting approaches.
