Based on the dataset, yield reaches maximum at 100 years. Which implication is most appropriate for long-term planning?

• A. Harvest around 60 years
• B. Harvest around 100 years for maximum yield
• C. Harvest any time since yield remains constant
• D. Harvest after 150 years for best value

Answer: (B)

If yield peaks at 100 years, the main takeaway for long-term planning is to time harvest to coincide with that peak to capture the highest possible yield per rotation. Harvesting around 60 years would miss much of the growth that accumulates between 60 and 100, resulting in a smaller total harvest. Waiting until around 150 years, while tempting to let trees mature further, typically won’t increase yield beyond the maximum reached at 100 and can risk declines in quality, more decay, or disturbances that reduce practical yield. Since yield changes with age and is not constant, the best strategy is to align harvest with the age at which yield is maximized—around 100 years.
