Which method uses partial retention of trees to seed new growth and provide wind shelter?

• A. Seed-tree method
• B. Clearcutting
• C. Shelterwood method
• D. Low thinning

Answer: (C)

Regeneration with protection is the key idea. The shelterwood method keeps a portion of the mature overstory in place to provide a windbreak and a ready seed source for the new generation. By leaving enough trees to shelter the future seedlings, the microclimate is more favorable—seedlings are shaded from harsh sun and drying winds, which helps them establish. After the seedlings are stocked and growing, the remaining mature trees are removed in subsequent cuts, releasing the new stand. This differs from leaving a few seed trees only for seed dispersal without long-term shelter, from removing all trees at once in a clearcut, and from thinning primarily aimed at improving growth rather than establishing a new generation under protective cover.
