Carolinian Forest

The Carolinian forest refers to a life zone in eastern North America characterized primarily by the predominance of deciduous (broad-leaf) forest. The term "Carolinian", which is most commonly used in Canada, refers to the deciduous forests which span much of the eastern United States from North Carolina northward into southern Ontario, Canada. These deciduous forests in the United States and southern Ontario share many similar characteristics and species, hence their association. Today, the term is often used to refer to the Canadian portion (northern limit) of the deciduous forest region, while the portion in the United States is often referred to as the "Eastern deciduous forest"

Carolinian Canada

The Carolinian forest in Canada is located at the southern tip of Ontario between Lake Erie, Lake Huron and Lake Ontario. The region contains an extremely high biodiversity of species, over 500 of which are considered rare. Research in the Carolinian zone has shown that many rare vascular plants are concentrated on specific landforms and within protected areas, showing the importance of conserving key landscape features of this region.

Lanark Country (including Perth) is part of the Canadian Shield and Great Lakes Basin. Of course to plants and wildlife borders don't mean much and things change with shifting geology, climate and human activity.

Old Growth Forests In Ontario

Prior to European settlement, Ontario and much of Eastern North America was dominated by large tracts of old growth forests. The arrival of European settlement, starting in the 1700’s, led to massive changes in the landscape and forest composition of Eastern North America. Settler activities such as logging, agriculture, and urban development contributed to these changes. Today, remaining old growth forests are few and far in between.
