Neco 2018 Agricultural Science Question 19
Practice objective / multiple choice question 19 from the 2018 Neco Agricultural Science examination.
A mixed forest covering 100 ha has an average tree height of 20 m and an average DBH (diameter at breast height) of 30 cm. The volume of a single tree (in m\(^3\)) can be estimated by \( V = 0.00005\, D^{2}\, H \) where \(D\) is in cm and \(H\) in metres. There are 500 trees per hectare. The stand's annual growth factor is 2.5 % of the standing volume, and the management plan permits harvesting at most 1.5 % of the standing volume each year to ensure sustainability. Determine the maximum annual timber volume (in m\(^3\)) that may be harvested from the whole forest.
