This region is right in the middle of our state, easy to get to from everywhere else. Its biome is sand plains and prairie. The landscape was largely shaped when it sat at the bottom of huge Glacial Lake Wisconsin, which left behind sandy soils and a fairly flat landscape.  One still can find eroded sandstone buttes, believed to have been islands during this time period, and certainly striking features as one travels through the region.  There are scattered mixed hardwoods and pine plantations, as well as large areas of wetlands and grasslands. Prairie Chickens do their spring dances in this region. The threatened Karner Blue Butterflies live here, as do river otters. Timber Wolves have reached their southern range in this biome.
