État de la populationTexte officiel évaluation IUCNExpert

Betula pumila is a common species across its broad geographic range. However, there are no hard data on population numbers due to it not being an important commercial species.

Ashburner and McAllister (2013) - consider this species to be more or less confined to the north eastern corner of North America, perhaps as relatively isolated populations.
