Which thinning targets mainly shorter trees with lower crowns?

• A. Mechanical/row thinning
• B. Low thinning
• C. Crown thinning
• D. Selection thinning

Answer: (B)

Low thinning targets trees in the lower crown classes—typically the shorter, suppressed individuals with small, lower crowns. By removing these lower-growth trees, the stand reduces competition for the remaining crop trees, allowing the taller, better-formed trees with higher crowns to grow faster in diameter and height. This approach focuses on improving the growth and quality of the dominant trees rather than widening the spacing by removing larger, canopy-dominant trees or selectively releasing individual superior trees. In short, it’s about clearing out the understory and suppressed trees to let the better trees in the upper canopy expand and thrive.
