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
The Saint Lawrence River is one of the most polluted in the world and these surrounding forests are vulnerable to clearance for agriculture and urban development including the cities of Montreal, Ottawa, Quebec City and suburbs of Toronto, Syracuse and Albany, New York. Less than 5% of natural forest remains intact. The fragmented blocks of remaining habitat include: the eastern end of Lake Ontario; Missisquoi National Wildlife Refuge in Vermont; the Chaumont Barrens, Rome Sand Plains, the Albany Pine Bush and the proposed Split Rock Wildway in New York; Bruce Peninsula (the barrier between Georgian Bay and the main section of Lake Huron), Alfred Bog, Luther Marsh, the Ganaraska Forest and Carden Plain in Ontario; and Mont Saint-Hilaire, Lac Saint-François National Wildlife Area and Cap Tourmente National Wildlife Areas in Quebec.
