Carolinian forest

[2][3] These deciduous forests in the United States and southern Ontario share many similar characteristics and species hence their association.

[2][3][5] The Carolinian zone spans across much of the eastern United States,[1] with extensive coverage in the Virginias, Kentucky, Tennessee, Maryland, Delaware, Pennsylvania, parts of southern New York state, Connecticut, and Rhode Island, eastern Ohio, and small parts of southern Michigan, Indiana, and western Ohio.

It extends up into Southern Ontario, Canada which is located in the fertile ecozone of the Mixedwood Plains and includes ecodistricts 7E-1 to 7E-6.

[8] This distinctive climate is largely due to the nearby Great Lakes which moderate the temperature of the surrounding land.

[1][9] Today, the Carolinian Zone contains major cities and is home to one quarter of Canada's population despite being 0.25% of the total land area.

[8] Some parts of the remaining natural area in the Carolinian zone are protected in an effort to conserve the region and its unique, diverse biota.
