Pierre, SD, USA / DRGNews Dec 23, 2020 7:19 AM The US Department of Agriculture Forest Service has drafted an environmental assessment for the Prairie Restoration Research Project on the Fort Pierre National Grassland in central South Dakota. The proposed action would supplement current land management with experimental prescribed burning, grazing and mowing to assess their effectiveness in reducing invasive grasses. Additional trials would be conducted on how to best establish native forbs and grasses and how to best produce native forb seed for future restoration efforts.
