A method for evaluating environmental quality of large-scale landscapes that bridges scientific research and public use is in great demand. Resource managers, industry and community planners, government policy-makers, and scientists all support an improved environment, but connections between processes, remediation, and management aren't always readily available or understandable to such a diverse community. This paper describes a versatile, simplified, science-based system for making environmental quality assessments and linking outcomes to remedial management. This complex goal becomes attainable by: establishment and use of appropriate scientific databanks, determination of targets for acceptable and unacceptable impact on critical ecosystem functions, simplified visual integration of many indicators, and linkage to management databases. The process is being developed by a multi-disciplinary study of a grassland ecosystem converted for use as a golf course. The system can be easily customized to local conditions and has wide-range application to many types of natural and managed ecosystems. Copyright ASCE 2004.
