A teak forest covers 500 ha with an average stand density of 120 trees ha⁻¹. Each tree currently has a DBH of 30 cm and a height of 20 m. Tree volume (m³) is approximated by V = 0.05 × (DBH)² × H, where DBH is in centimetres. Natural mortality removes 2 % of the trees each year and the average DBH increases by 0.5 cm per year (height is assumed constant). The manager wishes to harvest the same number of trees each year for the next 10 years, while ensuring that after each annual harvest the standing volume never falls below 80 % of the present total volume. What is the maximum number of trees that can be harvested each year (rounded down to the nearest whole tree)?
