Great Lakes - St. Lawrence Lowlands


In the Great Lakes - St.Lawrence Lowlands, we have a continental climate. Our range in temperature is good since there are no large bodies of water to moderate the warm temperatures in the summer and cold temperatures in the winter. There are also cool breezes in the spring and fall because of the region being close to the Great Lakes. The temperature in the region dramatically decreased since the ice age, making the temperature great.

Soil & Vegetation

In the Great Lakes - St.Lawrence Lowlands, we have deciduous and mixed forests. In the mixed forests, they use two types of trees. Both Deciduous and Coniferous trees. The humus created from leaves of the wide variety of trees creating a grey-brown topsoil rich in minerals for the trees. These soils in the mixed forests region are good for farming. Spruce, fir, pine, cedar, and hermlock woods are found in these forests with maple, beech, ash, oak and birch. These types of trees are a good resource for the lumbering industries. Over the years, this type of forest remains little in Southern Ontario due to the improvement of society and urban development.

The only Deciduous forests in Canada is found right here in the Grreat Lakes - St.Lawrence Lowlands. There is only a small part of this forest left since it was clered out for farming and urban development. In this part of Southern Ontario, the summers are long and hot while the winters are reletively mild, making precipitation lots. These weather conditions are good for hardwood trees like maple, beech, hickory, ash, and black walnut. These type of trees have soils that contain more humus and less acid since there is a large number of deciduous trees. This humus-filled topsoil is a dark brown colour. These trees need 5 months of warm weather to store it's energy to form sap in its trunks to survive the winter months.
