Birch is a common broadleaf tree. It is easy to recognize from its white trunk. 

The bark of a birch tree is mostly white in color, but it can grow rough and black as the tree ages. Birch bark has been widely used by humans as kindling and to produce tools and other objects. 

Birch wood is strong, tough and bends easily. This is why it is very suitable for making furniture, flooring and plywood. 

Birch trees grow in all kinds of locations. They are one of the most common tree species in Northern Europe. 

There are two types of birch trees. The leaves of the silver birch have a triangle-like shape. The leaves of the white birch have a round shape.

The leaf is attached to a branch by a thin stalk. The "lines" you can see running through the leaf are actually leaf veins. Water travels through these veins into the cells of the leaf.
