In point sampling, the basal area factor (BAF) is used to determine:

• A. The height measurement accuracy.
• B. The number of plots required.
• C. The amount of seed needed for planting.
• D. The calculation of basal area per plot.

Answer: (D)

The main idea is that Basal Area Factor sets how much area a counted tree represents in angle-count point sampling. When a tree falls inside the viewing angle, you take its basal area from its DBH (BA = (π/4) × DBH^2) and then scale that tree’s contribution by the BAF to reflect how much of the stand’s area that one tree represents. By summing these scaled basal-area contributions for all trees counted, you estimate the stand’s basal area per unit area (per plot or per hectare). So BAF is directly tied to calculating basal area per plot. It isn’t about height measurement accuracy, nor does it determine the number of plots required in a straightforward way (that depends on desired precision), and it isn’t about seed requirements.
