Paper Birch (Betula papyrifera), also known as American White Birch, Bolean Birch, Canoe Birch, Silver Birch and, Spoolwood is a species of birch native to northern North America, from Newfoundland west to Alaska, south to Pennsylvania and Washington, with small isolated populations further south in mountains to North Carolina and Colorado.

It is a medium-sized deciduous tree reaching 20 m tall (exceptionally to 35 m) with a trunk up to 80 cm diameter. The bark is white, commonly brightly so, flaking in fine horizontal strips, and often with small black marks and scars. In individuals younger than five years the bark appears brown with white lenticels, making the tree much harder to distinguish from other trees. The leaves are alternate, ovate, 5-12 cm long and 4-9 cm broad, with a doubly serrate margin. The leaf buds are conical and small, they are green colored with brown edges. The flowers are wind-pollinated catkins 3-8 cm long growing from the tips of twigs, the fruit matures in the fall. The mature fruit is composed of numerous tiny winged seeds packed between the catkin bracts. They drop between September and spring.
