The 30 m radius
plot was used to measure the DBH of trees >50 cm in diameter. The
15 m radius sub-plot was used to measure the DBH of trees of
20.1–50 cm in diameter. The 10 m radius sub-plot was used to
measure the DBH of trees of 10.1–20 cm in diameter. The 5 m
radius sub-plot was used to measure the DBH of trees of 5.1–
10 cm in diameter; while the 2 m radius sub-plot was used to measure
the DBH of saplings P1.5 m in height, but less than 5 cm in
DBH
