The University of Minnesota/Institute of Paper Science and Technology Aspen/Larch Genetics Project is located at the University's North Central Research and Outreach Center in Grand Rapids. Fast-growing plant materials are expected to play a significant role in meeting the burgeoning demand for aspen and more generally to insure ample timber for regional economic development. Scientists address tree improvement, specifically hybrid and improved aspen and larch seed production, mass propagation methods, and plantation establishment techniques. The Cooperative represents important industry and governmental action to maintain Minnesota's future timber supply. Andrew David directs this Cooperative.
