Ice Age Trail: Lodi Marsh Segment Professional Review and Guide
"Follow a guided nature loop across a hilltop prairie overlooking the marsh, then climb a bluff through forest and restored prairie with views of rolling farmland. Lodi Marsh and its springs surround the upper 2 miles of Spring Creek. They are breeding grounds for several species of birds, including great blue herons, sandhill cranes, willow and alder flycatchers, and blue-winged warblers. If you are into moths—and who isn’t?—this is a moth-rich environment, several of which are found only in wetlands.
Some rare species include the silphium borer moth, Newman’s brocade, and the ottoe skipper. On the south side of the marsh is a 240-foot knob hill partly covered with drymesic forest composed primarily of red oak, sugar maple, and basswood. The south slope, however, is prairie."
