Mazomanie Bottoms State Natural Area
Mazomanie Bottoms encompasses a large area of Wisconsin River floodplain forest dissected by old river channels that are dry except during periodic floods. Silver maple, elm, basswood, and ash dominate the forest; other trees include swamp white oak, cottonwood, willow, river birch, and hackberry. Openings in the canopy due to elm mortality have a dense understory of prickly ash, gray dogwood, buckthorn, and young trees. Ridges of sand support oaks but the slough margins are nearly pure silver maple. Vining plants and lianas are found in abundance: virgin’s bower, wild yam, moonseed, wild cucumber, woodbine, poison ivy, carrion flower, and grape. Sand bars and ephemeral pools along the river add considerable diversity. The forest harbors thousands of migrating birds. The site has a large woodpecker population and is used in winter by bald eagles. (Wisconsin Department of Natural Resources)
