Large areas of the Chequamegon-Nicolet National Forest (CNNF) are being impacted by spongy moth caterpillars. Spongy moth caterpillars have a voracious appetite for deciduous tree leaves and have left many areas nearly leafless, especially on the Washburn and Lakewood-Laona ranger districts. In some places, there are great lengths of leafless trees in areas that are typically lush with green tree leaves this time of year.
The following 10 counties in the CNNF are under quarantine for spongy moths: Ashland, Bayfield, Florence, Forest, Langlade, Oconto, Oneida, Price, Taylor, and Vilas. The quarantine aims to help reduce the spread of the spongy moth. CLICK HERE FOR MORE.
