In forest management, what does sustainable yield mean?

• A. Providing random timber outputs
• B. Harvesting all timber immediately.
• C. Providing an even flow of timber products, where harvest equals growth.
• D. A fixed annual harvest regardless of growth

Answer: (C)

Sustainable yield means harvesting at a rate that can be maintained indefinitely by matching removals to the forest's growth. In practice, this gives an even flow of timber products because the amount removed each year equals what the stand can regrow. This balance keeps the forest productive and healthy over time, rather than depleting it. Why the other ideas don’t fit: taking outputs randomly would be unpredictable and hard to sustain; harvesting all timber immediately ignores regrowth and future production; and setting a fixed annual amount without considering actual growth can either waste potential or deplete the stand, breaking long-term productivity.
