Silvical characteristics of paper birch (Betula papyrifera)

Abstract

Paper birch (Betula papyrifera Marsh) is commonly known also as white birch. The bark, which gives not only name but also unique character to this tree, is distinguishable from the white bark of other species by its pearly surface, its creamy cast, and its chalky whiteness that rubs off onto clothing. This bark separates easily into papery thin layers. Its smooth whiteness is marked with elongated horizontal lenticels.
