This trail allows the discovery of the Tillaie Integral Biological Reserve (RBI), where nature is left to evolve on its own. A remarkable ancient oak is there to
discover as well.
The Tillaie Integral Biological Reserve: Integral Biological Reserves were created by decree in 1953 to replace “Artistic Series” established in 1861 under the reign of Napoleon III (1852-1870). They consist in areas left free to evolve on their own. The only human interventions still allowed are scientific surveys, securing alleys that still exist, and hunting.
Dead wood: its decomposition allows soil enrichment. It is home to numerous insects, fungus, and birds. It is estimated that 25% of fauna and flora species in the forest rely on the presence of dead wood.
The Jupiter oak: this majestic oak, 6.7 meters in circumference, is still standing albeit dead since 1994. Its age at the time was estimated to be 650 years. 3 years of drought at the beginning of the 1990s prevented it from surviving any longer. It is surrounded by a fence for the sake of visitors’ safety.
All year round.
