The Wisconsin DNR is soliciting bids to power disc trench & apply herbicide on approximately 194 acres across 5 sites on the Black River State Forest in Jackson County. The objective of these applications is to prepare these sites for hand planting in 2027. And to reduce invasive & native plant competition in preparation for the future reforestation project.
