Birch trees are deciduous and have a thin papery bark that varies in color from tan to bright white. The bark tends to continuously peel off in sheets. The expansion of the trunk is what causes the bark to peel. A birch tree will have both male and female cones. The female cones will break apart in the fall, releasing hundreds of tiny seeds with wings. The tree is also known as the Canoe Birch because of the fact that Native Americans used the bark for constructing their canoes.

Birch has excellent turning properties and is used quite often to make spools, bobbins, dowels and bowls. It is highly valued as a plywood source. Birch is also used for flooring, doors, musical instruments, boxes, baskets and furniture making.
The wood of yellow birch is heavy, hard and strong. It has very good bending properties, with good crushing strength and shock resistance.
Birch wood works fairly easily, glues well with care, takes stain extremely well, and nails and screws satisfactorily where pre-boring is advised. It dries rather slowly with little degrade, but it has moderately high shrinkage, so is susceptible to movement in performance.
