The Study Team will select a set of ecosystem services that will be affected by watershed management, aquatic ecosystem, and water quality restoration. The model system will be used to simulate the effects of management measures on the production of ecosystem services. Rules for the spatial effects by number, geographic location, and area (as appropriate) of application of management measures on the production of ecosystem services will be developed. Monetary valuation of selected ecosystem goods and services will be estimated by applying accepted valuation methodologies and information from ecological economics literature sources. .
