For a 40-acre stand, how many plots are typically needed?

• A. Twenty-two plots
• B. Twenty plots
• C. Twenty-four plots
• D. Twenty-six plots

Answer: (A)

In forest sampling, the number of plots you use is a trade-off between precision and field effort. For a stand around 40 acres, a practical sampling intensity aims to capture enough variability in tree size, density, and species without making the fieldwork excessive. About two dozen plots hits that balance well: it provides a reliable estimate of average stand attributes (like volume per acre) while keeping the workload manageable. If you used noticeably fewer plots, the estimates would be less precise and more sensitive to how the stand happens to be sampled; using many more plots would yield diminishing gains in precision relative to the extra time and labor. Stand size and heterogeneity influence the exact number, but twenty-two plots is a common, sensible target for planning a 40-acre area.
