Research for Minnesota's forests

The risk of wildfires is high because of dense underbrush like balsam fir.

The Natural Resources Research Institute (NRRI) is working with the U.S. Forest Service to remove that wildfire fuel and turn it into a carbon-sequestering, soil-enhancing biochar material that can be used to cap landfills.
