Betula kenaica, or Kenai birch, is a species of birch that can be found in Alaska and northwestern North America at 300 m (980 ft) above sea level.[1]


It grows up to 12 m (39 ft) tall, with reddish-brown bark that may become pink or grayish-white. The leaf blades are ovate and grow in 2-6 pairs which are 4–5 cm (1.6–2.0 in) (sometimes up to 7.5 cm (3.0 in)) long and 2.5–4.5 cm (0.98–1.77 in) wide. The leaf margins are cuneated and serrated with rounded base and acute apex. The flowers bloom in late spring while fruits fall in autumn.[2]


The buds and twigs of the plant are used as a stew flavor while its inner bark can be eaten either raw or cooked and can be used as soup thickener. The sap is used to make honey.[1]
