The map below is based on data by the European Space Agency (the CCI project). It shows the two different types of forests in Europe: dark green represents needle-leaved trees (mostly evergreen); light green represents broad-leaved trees (virtually all deciduous):
The needle-leaved trees are mostly spruces, pines, and firs (all evergreen), with some (deciduous) larches mixed in especially in the Alps and Central Europe. The broad-leaved trees (all deciduous) are more varied: ashes, beeches, hornbeams, oaks, and poplar trees are widespread in most of Europe, alders in Eastern Europe, and chestnuts in Southern Europe.
