Amazing autumn colours in Kejimkujik National Park, Nova Scotia, Canada. The vividly coloured trees are almost certainly Red Maple trees (Acer rubrum), a native species of the area - which grow near the waters edge because, unusually, they can withstand frequent flooding.
In the past the National Park formed part of the traditional canoe route for the indigenous Mi'kmaq people to cross from the Atlantic coast of Nova Scotia to the Bay of Fundy. Today it's a National Park (established in 1967) covering 381 square km.
The spectacular colours are caused by the usually dominant green chlorophyll breaking down to show the reddish anthocyanins contained within the leaf structure.
