Current Working Groups and Research Teams
www.prairiestrips.org: An interdisciplinary team of researchers are investigating native prairie strips as a tool for improving the function and integrity of row-cropped farms. The project, STRIPS (Science-based Trials of Rowcrops Integrated with Prairie Strips), shows that small areas of perennial prairie, strategically placed on the contours and foot slope of a row-cropped watershed, provide multifunctional benefits for farmland health. The STRIPS experiment began in 2008 on 14 small watersheds at the Neal Smith National Wildlife Refuge.

Iowa Cover Crops Working Group: The Iowa Cover Crops Working Group is part of the Midwest Cover Crops Council, which is a working group affiliated with Green Lands, Blue Waters. The mission of the MCCC is to significantly increase the amount of continuous living cover on the Upper Midwestern agricultural landscape.
Cropping Systems Research Team: The Cropping Systems Research Team has found that adding small grains, red clover and/or alfalfa to corn-soybean cropping systems can greatly reduce the need for fossil fuels, chemicals and synthetic fertilizers, without sacrificing yields or profitability. The project has been funded by Leopold Center competitive grants, the USDA National Research Initiative, the Iowa Soybean Association, and the Organic Center.
Mid-American Agroforestry Working Group: The Mid-American Agroforestry Working Group (MAAWG) is an organization for advancing the science, practice and adoption of agroforestry by landowners and natural resource managers in the Midwest region of the U.S. The group is not a political or advocacy organization but is focused on promoting the adoption of agroforestry in the Mid-American region through expanding knowledge, coordinating and leveraging resources, and building stakeholder capacity.
Life Cycle Assessment: LCA is a biophysical accounting framework that has been standardized by the International Organization for Standardization (ISO). LCA involves compiling an inventory of the material and energy inputs at each stage of a product life cycle, and quantifying how these flows contribute to specific resource use and emissions-related environmental impacts. This research approach can be used to examine energy use, greenhouse gases, and other emissions associated with products, livestock, and crop production systems. The Leopold Center has funded or collaborated on several LCA-related projects.
