Erik A. Lehnhoff

Assistant Research Professor Ph.D. Ph.D., May 2008, Department of Ecology and Environmental Science, Montana State University, Bozeman, MT. Master of Science, May 1994, Civil and Environmental Engineering, Tennessee Technological University, Cookeville, TN. BS, May 1993, Civil Engineering, Clemson University, Clemson, SC. Research interests include evaluating the impacts of non-native invasive plants on ecological community structure and function; multi-trophic interactions involving invasive plants and their herbivores, pathogens and pollinators; improving surveying and monitoring techniques for invasive plants; understanding factors influencing invasive plant distributions; integrated management of weeds.
