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.
Southwest Elgin Forest Complex
The Southwest Elgin Forest Complex comprises a 20-kilometer subzone of discontinuous woodlots in southern Ontario within 5 kilometers of the Lake Erie shoreline from John E. Pearce Provincial Park at the eastern end to the Elgin-Kent county border at the western end. Mature forests are often dominated by American beech and sugar maple with a notable presence of species, including sassafras and tulip tree, which are restricted to the Carolinian forest region. Some rare birds are present, most notably hooded warbler in woods and Acadian flycatcher in ravines.
