This research program was initiated in 1999 as part of an SDSU Agricultural Experiment Station funded program in the laboratory of Dr. R. Neil Reese. This project is designed to provide research and educational opportunities to students interested in conservation and utilization of native plant species, as well as encourage the use of native plants by small family farmers as alternative crops in South Dakota.
