Cost (C) = Cost of harvesting + handling. Hence, Profit = Revenue − Cost. Since the benefit is generated over multiple years, it is necessary to calculate that particular age of harvesting which will generate the maximum revenue. The age of maximum revenue is calculated by discounting for future expected benefits which gives the present value ...

[6] Oak wilt is major cause of oak mortality in some regions and has been detected in 24 US states.
