La France sauvage S01E03 - Les Vosges, la forêt mystérieuse

The ancient upland forests of Western Europe are living monuments. They are home to a wealth of plant and animal species: large mammals and microscopic insects live side by side beneath the tall trees. In upland forest, life is governed by the daylight cycle. The course of the sun influences plant growth and animal behaviour. Upland forest is one of Europe's distinctive natural ecosystems.
