In the new ecohydrology major at the University of Nevada, Reno (UNR), students learn about the relationships between hydrologic mechanisms and ecological patterns and processes in watersheds and aquatic systems. The curriculum provides students with the option of meeting the requirements for federal positions as a hydrologist (GS 1315) and is designed to provide physical scientists with a strong secondary emphasis in ecology. This paper describes the development of this novel undergraduate degree in ecohydrology and some of the challenges involved in its development and implementation. (Contains 2 tables.)
