Neco Model Questions Vol1 2017 Agricultural Science Question 43
Practice objective / multiple choice question 43 from the 2017 Neco Model Questions Vol1 Agricultural Science examination.
A forest manager oversees a 100‑ha teak stand with an average density of 250 trees ha\(^{-1}\), mean DBH of 30 cm and mean height of 20 m. Tree volume (m\(^3\)) is estimated by \( V = 0.0005 \times DBH^{2} \times H \). The average annual growth is 0.8 cm in DBH and 0.5 m in height. To keep the stand's total volume constant, the manager must harvest each year a proportion of trees equal to the relative increase in total stand volume. How many trees can be harvested annually?
