From Marshfield Fire & Rescue: Effective tomorrow, 3/27/2020, the decision was made to implement a suspension of all annual and special burning permits will be suspended until further notice as an attempt to limit exposure of firefighters and the public.
A majority of forest/grass-related fires in Wisconsin are caused by humans. This is an attempt to limit the burning right now which in turn will reduce the likelihood that firefighters need to interface with the public.
Hang in there, and please contact the DNR if you have any questions.
