When you walk across the land or boat across the water, do you notice the range of plants growing on different types of land? For example, the plants that grow in muskeg areas are very different from those growing on bare rocky areas. This is a pattern repeated over and over.
While observing this, have you ever wondered if geology plays a role in controlling where different types of plants grow?
There is a strong link between Ontario’s geological history and the location of different types of plants. We know that geological forces shaped the land. And yes, geological forces also created habitats – special places where distinctive plants grow. Obviously, different habitats are home to different plants. So, the type of rock and the type of deposit left behind by glaciers are key factors in determining the distribution and types of some plants.
Ontario’s long and complex geological history created many different habitats that sustain different types of plants in different areas.
