The removal of diseased ash and beech trees is underway at Potawatomi State Park in Sturgeon Bay. Those trees are infested by the emerald ash borer and beech bark disease. Some tree cutting will take place in Potawatomi Parks campgrounds and Superintendent Erin Brown Stender says winter campers need to be cautious.

The harvest of the diseased ash and beech trees will take place through May 15th  Those trees will be used for pulp and the remainder used for building materials.
