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".
The Carolinian zone spans across much of the eastern United States, 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.
Trees found here include various species of ash, birch, chestnut, hickory, oak, and walnut; tallest of all is the tulip tree. Fruit trees native to this zone include the pawpaw. Animal life includes raccoons, opossums, squirrels (including the relatively rare southern flying squirrel), nuthatches, and chickadees. The Carolinian forest is among the most biologically diverse regions in Canada, with over 2,200 plant species, 400 bird species, and more than half of the country's at-risk species.
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.
The Canadian portion of the Carolinian forest supports an unusually high concentration of rare vascular plant species compared with other regions of the country.
Research on plant distributions in southern Ontario has shown that many uncommon species are clustered on landforms such as sand plains and other specialized habitats. Protected natural areas play an important role in conserving these species, as a significant proportion of documented rare plant occurrences have been recorded within parks and reserves. Examples of rare or regionally significant plant species include Asimina triloba (pawpaw), Sassfras albidum (sassafras), and Opuntia humifusa (eastern prickly pear cactus), which occur in scattered populations in Carolinian Canada.
The reason for the high biodiversity in this region is its unique climate, ranging from humid subtropical to a mild humid continental. The Carolinian forest of Ontario has the warmest average annual temperatures, the longest frost-free seasons, and the mildest winters of any region in Ontario and Canada in general. This distinctive climate is largely due to the nearby Great Lakes which moderate the temperature of the surrounding land. Climate records show that the Carolinian region, as part of the Great Lakes-St. Lawrence basin has already warmed over the past century, with the largest increases occurring in winter and spring. This warming is associated with longer growing seasons and changing precipitation patterns that affect forest water balance and ecosystem processes. The climate of the region is strongly influenced by the Great Lakes, so even relatively small shifts in temperature and evaporation can alter habitat conditions in Carolinian forests.
Projected climate change may further influence forest composition and resilience in southern Ontario by increasing stress on some common tree species and shaping management responses in both urban and natural landscapes. Natural disturbance patterns such as wildfire in the broader Great Lakes-St. Lawrence Forest is also shaped by interactions among climate variability, short-term weather conditions, and landscape characteristics.
