The Southern Great Lakes lowland forests is a temperate broadleaf and mixed forest ecoregion of North America, as defined by the World Wildlife Fund. Located near the Great Lakes, it lies mostly in the central northeastern United States and extends into southeast central Canada. In modern times, little of it remains intact due to land use, including agriculture and urban uses.




Setting


This area includes the southern half of Michigan's Lower Peninsula, and much of Indiana and Ohio. It also extends through the southern half of Southwest Ontario from Windsor to Toronto and into Pennsylvania and New York on the southern rims of lakes Erie and Ontario.
This region is characterized by warm-to-hot summers and mild-to-cold, snowy winters.




Flora


This ecoregion is associated with the temperate deciduous forest with the forest being dominated by Acer rubrum, Acer saccharum and Fagus grandifolia, Prunus serotina, Carya ovata, Quercus alba, and Quercus rubra. Other trees that may be found in the forest include Fraxinus americana, Liriodendron tulipifera, Cornus florida, Sassafras albidum, Juglans nigra, Tsuga canadensis, and Juniperus virginiana. Pure stands of Pinus strobus are sometimes common. In more marshy areas, Populus deltoides, Populus tremuloides, Nyssa sylvatica, Betula populifolia, Betula nigra, Larix laricina, and Thuja occidentalis are common.




Fauna


The Southern Great Lakes forests were very rich in wildlife. Birds include cardinals, downy woodpecker, wood duck and eastern screech owl. Large mammals including American black bear (Ursus americanus), moose (Alces alces), Canada lynx (Lynx canadensis), cougar (Puma concolor), caribou (Rangifer tarandus), elk (Cervus canadensis) and eastern wolf (Canis lycaon) have been mostly or completely extirpated from this ecoregion; remaining mammals include white-tailed deer (Odocoileus virginianus), coyote (Canis latrans), snowshoe hare (Lepus americanus), eastern chipmunk (Tamias striatus), American red squirrel (Tamiasciurus hudsonicus) and eastern gray squirrel (Sciurus carolinensis).




Threats and preservation



Because of extensive urbanization and agricultural use very little of this habitat remains intact.
