Sarmatic mixed forests, Mixed forest ecoregion in central Russia.

The Sarmatic mixed forests are a WWF ecoregion (PA0436) of about 846,100 km², running from southernmost Norway, southern Sweden and southwestern Finland through the Baltic states and northern Belarus into central European Russia. Quercus robur, Picea abies and Pinus sylvestris dominate; the spruce thins southward where moisture fails. Belovezhskaya Pushcha is its best-known example, and the Neris Regional Park marks the transition to Central European mixed forests.
