paper birch (Betula papyrifera)
How big are paper birch?
Paper birch can grow to be over 80 feet tall and 16 inches in diameter.
How long do paper birch live?
Paper birch can live about 120 years.
What do their leaves look like?
Their leaves are broadly wedge shaped and 1 1/2 to 3 inches long.
They have an uneven tooth-like edge around the leaves. They loose
their leaves in the fall and grow new ones in the spring.
What does their bark look like?
Their bark is thin and smooth, dark red or brown on the new stems.
As the tree grows the larger branches turn a creamy white color.
The bark will often shed in large paper like sheets. If you remove
the outer layer of bark you will find a reddish orange layer. If
you peal off too much bark you can kill the tree. Birch bark is
very good for starting fires. However, it is important to remember
that you should only take bark off of downed trees, not live or
standing trees.
Where do paper birch live?
Paper birch are often found on the edges of lakes and forest edges.
They are not shade tolerant and need a lot of light to grow and
develop. They are often among the first trees to grow in an area
that has been burned of logged. They are a northern tree and are
found in the northern United States and most of Canada.
What are some other cool fact about paper birch?
Traditionally birch bark played a very important role in the Ojibwa
culture. Their summer and winter houses were made out of birch bark.
The bark was used to cover the out side of the shelters to keep
out the wind and rain. They also used the bark to make birch bark
canoes which were their main form of transportation in the summer.
When the Hudson Bay Company and the North West Company began trading
furs in the 1700 the native people were hired to build birch bark
canoes for them to use in their trading. Some of these canoes were
able to carry sixteen people and 8,000 pounds of cargo! You can
also make birch syrup out of the sap which is similar to maple syrup.
However, the sugar content in birch sap is not as high as maple
tree sap so you have to boil the sap longer to make syrup.
