When should trees be harvested?

• A. When they are mature.
• B. When they are young.
• C. When they show minor defects.
• D. When markets are favorable.

Answer: (A)

Harvesting at maturity is the best choice because it aligns with the growth and quality goals of a forest rotation. When trees have reached harvestable size and the stand has developed the desired form and wood characteristics, removing them maximizes the value of the crop and makes regeneration efficient. Harvesting while trees are young wastes the substantial growth stored in the bole and can yield a lower-quality timber product. Minor defects in some trees don’t automatically set the timing for the whole stand, and favorable markets influence economics but don’t override the biological timing of when timber reaches its optimal size and quality.
