It is wind-blowing, and its light seeds provided with wings are spread by the wind often over long distances, which is why birch is one of the first species of trees overgrowing wasteland (pioneer species). Occurs on dry, sandy areas, on wasteland, in deciduous forests, mixed and pine forests, in bushes and on felling sites, along railway routes. It is also an important forest tree.
