Report an issue with this species

Gray birch is a deciduous tree known for its gray, non-peeling bark and triangular leaves. It is a highly adaptable pioneer species, tolerating various soil and moisture conditions, often forming thickets in disturbed sites. Though short-lived and with poor drought tolerance, it is used ornamentally and grows rapidly in its early stages.
