areas with some topographic relief and better
drainage, beech, maples, basswood, tulip tree and
other more mesic species were dominant. On elevated beach ridges and moraines with good to
excessive drainage, more xeric species, especially
oak and hickory, were dominant. Unlike other
swampy areas of the Great Lakes, such as northern
Minnesota, there were no conifers. The area
contained non- forested wetlands, particularly
marsh and wet prairies, with marshes being particularly extensive along the Lake Erie shoreline
between Toledo and Sandusky. Some of these
exist even today in modifi ed form in state and
federal wildlife refuges, such as Ottawa National
Wildlife Refuge.
