Landscape-scale experiment examines impacts of harvest of federal grasslands in Wisconsin as tool for habitat management with potential bioenergy benefits.

“Thumb"The U.S. Fish and Wildlife Service Leopold Wetland Management District in Portage, WI is exploring late-season haying of its grasslands? as a habitat management tool to augment prescribed fire. The District also sees potential for use of the haying byproducts (i.e., biomass?) as a bioenergy? source, which can go towards meeting agency policies and directives to reduce reliance on fossil fuels and to reduce carbon footprint. Since 2012, the District has partnered with University of Wisconsin to verify the ecological soundness and technical feasibility of harvests and to determine if this habitat management tool meets management goals. University experts in transdisciplinary collaboration, wildlife ecology, agronomy, and entomology have been part of the effort.
