Nine months after its first prescribed burn in 150 years, a 22-acre patch of forest on Wisconsin Point is starting to show the effects. On one side of the road to the beach, the understory, or plants growing from the ground, are tall and dense. It’s not what a healthy red pine forest should look like, said Callie Grones, an outreach coordinator with the Lake Superior National Estuarine Reserve. On the other side at the “burn unit,” the ground is a little clearer, although still very green, the bottoms of the pine trees are charred and wild blueberries are thriving. …“Ojibwe people, when they were living out here, they used fire almost in a routine,” Grones said. The forest’s health was maintained through that fire.” … Stewardship Coordinator Kirsten Rhude said it will take a few years before the full advantages of the burn appear.
