Betula davurica Pall.
Берёза даурская, чёрная /Daurian birch, Asian black birch

The crown's shape is oval or egg-shaped with the upwards and inward directed branches.
It has a height of 25 m and trunk diameter of 50-70 cm.
It grows in the oak-woods and oak-cedar forests. It reaches elevations of 300-400 m above sea level.
Thrives in sunny locations and is fairly winter hardy.
