Jeffrey Evans is a Senior Landscape Ecologist for The Nature Conservancy’s Conservation Lands Team. His focus is on the development of new statistical tools for evaluation of impacts to biodiversity, habitat quality and prediction of energy development potential. Working extensively on the Conservancy’s Development by Design strategy, he works on using predictive models to develop solutions that benefit conservation outcomes. Jeffrey is involved in his own research, with collaborators at University of Wyoming, USFWS, NRCS, University of Minnesota and various TNC scientists, in diverse topics such as spatial statistics, remote sensing and landscape genetics.

Senior Landscape Ecologist, Conservation Lands
Jeffrey Evans is a Senior Landscape Ecologist for the Conservation Lands global team. His focus is on the development and implementation of statistical methods for the assessment of cumulative impacts to ecosystem system services, biodiversity and habitat integrity resulting from energy development and other land conversion. Jeffrey has been pioneering the use of novel nonparametric statistics for predicting species distribution, energy development potential and habitat use and has also recently developed a new method for understanding ecosystem rarity. Broadly, his research has focused on ecological modeling, species distribution, climate change, understanding landscape dynamics, and the development of new remote sensing technologies. He currently has over 65 publications in peer-reviewed journals.
Jeffrey received his Ph.D. from University of California Berkeley in ecology and statistics and holds an affiliate assistant professor position at the University of Wyoming. He is one of the lead scientists for the USDA-NRCS Sage Grouse Initiative. This is an effort to provide relevant science-based information to guide proactive “on-the-ground” management activities to help avert an ESA listing decision. He is also a technical advisor to the USFWS Prairie Pothole waterfowl science team and provides broad technical support to various TNC efforts. Prior to TNC he worked as a research ecologist for the USFS Research Station, held affiliate assistant professor status at the University of Idaho and worked at the California Academy of Sciences as a Research Assistant. He has also ridden horses for 35+ years and was a member of the US Equestrian team for two years. Jeffrey has been married to Dr. Melanie Murphy for thirteen years and together they have two dogs and three horses.
