Large Tree Removal in Wisconsin

Wisconsin regulates oak wilt timing through guidance rather than permits; removing a private tree is a local matter, and cities like Milwaukee manage street trees themselves. In Milwaukee, the Department of Public Works Forestry Services manages street and boulevard trees, including pruning, removal and stump grinding; residents request service through the city.
