Optimal Level of Expenditure to Control the Southern Pine Beetle

摘要

Optimal level of expenditure to control damage to commercial timber stands by the southern pine beetle was determined by models that simulated and analyzed beetle attacks during a typical season for 11 Southern States. At a real discount rate of 4 percent, maximized net benefits for the Southern region are estimated at about $50 million; at 10 percent, more than $30 million. Methods and costs for detection, evaluation, and suppression of beetle infestation are discussed. Tables of optimal level for the 11 States are included.
