AIS Activities on the Chain this Summer

Weeds are the topic of many of our members this summer. 

Staying true to our commitment as an Association and to our members, we continue to educate and treat in the areas where we are allowed.  Our latest update below shows dates and maps of both mechanical harvesting and chemical treatments.  These areas are determined by the DNR and the permits we were able to secure, along with our budget and also areas in which are used as navigational routes.  For maps of these treatment areas, go to the Projects page.
