It grows quickly and is short lived, with a life span of some 60 years. It is a typical pioneer species and can colonise bare ground. An alder may be distinguished from a birch tree by its usually stalked winter buds and by conelike structures that remain on the branches after the small winged nutlets are released. The scaly bark is grayish brown in some species and almost white in others. The oval leaves are alternate, serrate, and often shallowly lobed; sticky on unfolding but glossy when mature, they fall without changing.
