The Wisconsin Department of Natural Resources (DNR) has finalized aerial spraying plans for its 2024 Spongy Moth Suppression Program, with maps for the six selected treatment areas available online.
The treatment sites contain high-value trees at six state parks or forests in Columbia, Marinette, Sauk and Walworth counties. A total of 928 acres will be treated with an aerial spray of “Foray” bacterial insecticide containing Bacillus thuringiensis var. kurstaki.





On April 20, the First Downs for Trees program celebrated its 13th year by distributing 403 trees to 16 Brown County communities for planting. First Downs for Trees is a cooperative effort between the Wisconsin Department of Natural Resources (DNR), the Green Bay Packers, Wisconsin Public Service (WPS) and corporate sponsors Essity and Green Bay Packaging, Inc.
