Carolinian Life Zone - from The Ruthven Park Nature Blog - Carolinian Forest Fact Sheet
"The “Life Zone” concept was developed in 1889 by C. Hart Merriam, an American zoologist and a founder of the US National Geographic Society, as a means of describing areas with similar plant and animal communities.
The Carolinian Life Zone is centred in the Carolinas in the United States and is found in Canada only in the southwestern section of Ontario. Carolinian forest is characterized by a predominance of deciduous, or broad-leafed, tree species.
Although only approximately 1% of Canada falls within the Carolinian Life Zone, more species of plants and animals are found here than anywhere else in Canada. Over 2200 species of plants are found within the Carolinian zone in Canada."
We're Canada's bio-diversity "hot spot" but we also have the challenge of more rare / species-at-risk than anywhere else in Canada.
