Flora and fauna

The island has become the home of a breeding colony of double-crested cormorants.[2] Their droppings have threatened the forest, a relict of Carolinian forest in southern Ontario.[3] The forests of the island are dominated by the common hackberry and Kentucky coffeetree.[4] Unusual species on the island include the wild hyacinth[5] and the Lake Erie water snake, Nerodia sipedon insularum.[6]
