Guide to Birches of NYC in Winter

Birches (Betula spp.) are small to medium-size trees and shrubs found in temperate zones of the Northern Hemisphere, used extensively for their wood and bark. New York City is home to five native species of Birch, recognized in winter by their bark, buds, and scent. Betula populifolia (grey birch) and B. lenta (sweet birch) are common; three others are less often seen: B. nigra (river birch), B. alleghaniensis (yellow birch), and B. papyrifera (paper birch).
