What does sustainable yield mean in terms of harvest and growth?

• A. A fixed harvest above growth
• B. An uneven flow of timber products
• C. Providing an even flow of timber products, where harvest equals growth.
• D. No harvest at all

Answer: (C)

Sustainable yield is about balancing removals with the forest’s natural increase so the stock stays roughly constant over time. The best description captures an even, reliable supply where what you harvest in the long run equals the forest’s growth. When harvest matches growth, the standing volume doesn’t steadily decline or rise, allowing a steady stream of timber year after year. If you harvest more than the forest grows, the stock would gradually shrink and future harvests would need to be reduced. If you harvest less than growth, the stock increases, but the goal of a steady, predictable flow of wood can be undermined. An uneven flow fails to provide a stable supply management aims for. No harvest means no production, which isn’t a sustainable utilization of the resource.
