Aquatic Plant Control Research Program: Literature Review of Economic Valuation of Aquatic Plant Control

Abstract : Aquatic plant control is necessary to maintain the flow of benefits for which water resources projects are constructed and operated (e.g., flood control, water supply, or recreation). The costs associated with acquatic plant control have documented by the US Army Corps of Engineers, but little work has been performed by the Corps to evaluate the economic benefits resulting from aquatic plant control programs. This report reviewed the applicability of the project evaluation guidance, Principles and Guidelines (P and G), for the evaluation of aquatic plant control benefits. It was determined that the approach to economic valuation set out in P and G could be used for valuing aquatic plant control benefits. Corps, State, and academic studies and reports were reviewed for valuation of aquatic plant control benefits. In the majority of cases, aquatic plant control benefits. In the majority of cases, aquatic plant control benefits received only cursory treatment. In some cases, few details of the benefit estimation procedures are offered, making it difficult to judge the reliability of the benefit estimates. The majority of project evaluations were based solely on the recreation benefits.
