If base age is 50 years and the stand reaches 50 feet tall at that age, what does this indicate about site productivity?

If base age is 50 years and the stand reaches 50 feet tall at that age, what does this indicate about site productivity?

• A. It indicates poor productivity
• B. Height is irrelevant
• C. It indicates the stand meets the base-age height criterion for productivity
• D. It indicates rapid height growth but not productivity

Answer: (C)

Site productivity is often judged by how tall a stand is at a standard base age. If the stand reaches the target height set for that base age, it shows the site can support that level of growth, meaning it’s productive. In this scenario, with a base age of 50 years and a height of 50 feet at that age, the stand meets the base-age height criterion for productivity. That’s why it indicates a productive site. If the height were below the target, it would suggest lower productivity, while simply noting rapid height growth isn't the criterion by itself; the important point is meeting the established base-age height.
