D10: River Birch, Betula nigra

The River Birch was introduced from the eastern USA (Minnesota to Florida) in 1736. It favours wet acid soils commonly occurring in floodplains and swamps. It is unusual for a birch in that it can tolerate high summer temperatures. The bark changes characteristics with age, becoming shaggier with maturity. It is commonly multi-stemmed and can grow to 25 m.
