Southern Ontario
Southern Ontario has a very different climate from the rest of the country. It is the only area of Canada that has Carolinian forest. Many trees, plants, and wildlife in Southern Ontario are not found anywhere else in Canada. Some rare trees to Canada in this region include the tulip tree, pawpaw fruit tree and the cucumber tree. The Carolinian forests of Southern Ontario have in large part been destroyed by development sprawl. Very few original growth areas remain.
Eastern Great Lakes lowland forests
This area includes much of northern New York state (save for the Adirondacks), western Vermont, the Saint Lawrence Lowlands in southern Quebec and most of southern Ontario between Lake Ontario and Georgian Bay on Lake Huron. The region includes the Frontenac Axis, the Niagara Escarpment up to Manitoulin Island on Lake Huron, and Lake Simcoe. Meanwhile, the forests south of Lake Ontario are classified as the Southern Great Lakes forests ecoregion and in Canada the higher elevations of the Canadian Appalachian Mountains and the Laurentian Mountains constitute the Eastern Canadian forests.
