On the north side of the arboretum from the visitor center, this hike through part of a 28-acre deciduous forest and wetland features wildflowers growing along the paths in both spring and fall. In the 1830s, after pioneers extinguished prairie fires that had prevented trees from taking root, oak trees began growing in the area, originally a prairie and savanna. After the University of Wisconsin acquired the land in the 1930s, scientists planted sugar maples to replace those that had been removed through log- ging, and today fully grown maples provide a dense canopy of shade among the oaks. Other trees found in the woods, some planted by researchers studying plant life, include shagbark hickory, black walnut, birch, elm, ironwood, tulip poplar, and magnolia. In the center of the thick stands of trees, Teal Marsh is a wetland home for waterfowl as well as frogs, muskrat, mink, and owls. There are excellent bird watch- ing opportunities in the woods, which are also dotted with Native American burial mounds, some dating back to cultures more than 1,000 years old.
