Department: Natural Resource Ecology and Management
Research Interests: Professional interests include riparian ecology, management and restoration, especially in agricultural landscapes, hydrology and soils, agroforestry.
Brief description of current research:
Research emphasis focuses on the design and function of riparian management systems that reduce the movement and remediate the impact of non-point source pollutants from croplands and pastures to adjacent streams. Presently we are also studying the impact of riparian buffers on stream bank stability and quantifying the proportion of stream sediment that originates from bank erosion and surface erosion. We are also studying carbon sequestration in and evolution of greenhouse gases from buffers and other communities. Most of our buffer designs use perennial woody and forb species that are functionally effective and provide potential alternative income to land owners. An area of study includes quantifying the biomass production potential of buffers for carbon sequestration and use in the burgeoning bio-energy field.
