What is the basal area factor (BAF) for prism plots mentioned?

• A. BAF 10.
• B. BAF 5
• C. BAF 15
• D. BAF 20

Answer: (A)

Basal area factor shows how much basal area per acre each counted tree represents in prism sampling. In fixed-angle prism plots, the estimated basal area per acre is obtained by summing the BAF value for every tree counted. The prism plots described use a BAF of 10, so each counted tree contributes 10 square feet of basal area per acre to the total. That choice balances practicality and precision for many stands. If you used a smaller BAF, you’d count more trees and spend more time sampling; with a larger BAF, you’d count fewer trees and potentially lose precision in denser stands.
