The North American craton is the bedrock forming the heart of the North American continent and the Canadian Shield is the largest exposed part of the craton’s bedrock. The Canadian Shield is part of an ancient continent called Arctica, which was formed about 2.5 billion years ago during the Neoarchean era.

Why do trees grow in the Canadian Shield?
This region only has a thin layer of soil, yet the trees in the Canadian Shield only require a small amount of soil to grow, since they cannot root into rock. This region tends to have long cold winters and warm dry summers, therefore all the natural vegetation is able to survive during these conditions.
