River birches have papery bark that’s considered scaly, and often has multiple thin trunks rather than one large trunk. River Birch functions as an ecologically valuable species because of their flood-resilience and ability to mitigate impacts of acid mine drainage. The bark of river birch is also considered a survival food. As an ornamental tree, the DURAHEAT cultivar is very similar to the Heritage cultivar in that it is a lighter colored tree that is resistant to the bronze birch borer, a beetle. The bark of DURAHEAT is shinier than that of Heritage, growing 40’ tall and 30’ wide.
