White tailed deer (Odocoileus virginianus) can often be spotted along the Humber River. Many mammals such as the white tailed deer use ravines and connected greenspace as natural corridors to navigate urban development. This explains why large mammals are sometimes spotted in highly urbanized areas along the Humber River. The Terrestrial Natural Heritage System Strategy is one way TRCA is working to protect natural heritage such as wildlife corridors within the Humber River watershed.
