Expertise
Landscape assessments looking at relationships between land use patterns and indicators of water, air, habitat, and quality of life. Focus on the use of statistical and geospatial analysis in cooperation with multi-disciplinary teams. Developing studies to assess land use management scenarios and evaluating impacts on water quality protection. Development of work plans, metrics, and tools for projects in order to develop methods of a comprehensive assessment, combining databases from multiple fields of study, including Land, Air, Water, Human Health, and Socio-Economics to identify cumulative effects on current and future conditions. Development and application of agro-ecology, ecosystem ecology, soil erosion and erosion models, as well as physical, chemical and biological water quality data, collecting and filtering, and statistical analysis, as applies to landscape ecology and watershed assessments.
