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.
Mixedwood Plains Ecozone (Canada)
Owing to its southern location, it initially had a high natural biological diversity. For example, the Lake Erie Plains region has the highest tree diversity in Canada, with species such as tulip tree, cucumber tree, pawpaw, black gum, sassafrass and black oak. American chestnut was common in this region before the arrival of chestnut blight, though it is now very rare. The area also has a high diversity of songbirds, reptiles and amphibians.
