Factsheet S05: Silver birch – Betula pendula
The silver birch is native to Europe and Asia, forming large colonies in the north of its range in Finland and Russia. It is an extremely hardy pioneer tree, growing farther north towards the arctic and higher up mountains than most other trees; it is hardy in zone 2 (-45°C, -50°F). It is found growing in light woods, clearings, on mountain slopes and rocky areas; it is often found growing on acid infertile soils. Natural regeneration is usually vigorous and huge quantities of seed are regularly produced. In Britain it forms 12% of the existing broadleaved high forest.
