Abstract:
Much forest land in Western Oregon has been lost to production due to brush competition. As the demand for forest products increases,
more attention should be paid to the reclamation of these unproductive lands.
Chemical herbicides have been proven an efficient tool for brush control from the physiological viewpoint. This study uses the internal rate of return and benefit-cost ratio analyses for the economic evaluation of herbicidal brush control for decision-making
under certainty. A general sensitivity analysis is conducted and discussed in terms of the changes in stumpage price and interest rate. The internal rates of return and benefit-cost ratios are given as guidelines to forest managers in decision-making. The possibility of using decision-making under uncertainty has been explored and explained. The maximum expected value was used as a criterion in decision-making process.
