An exceptional abundance
Whilst 272 species of bird have been spotted since the reserve was created, the site is not an ornithological park. Like all nature reserves, the habitat is protected first and foremost - with all its flora and fauna. Since 1976, nature inventories and monitoring procedures have counted:
- 339 species of plants,
- more than 1050 species of insects,
- 102 species of spiders,
- 33 species of mammals,
- 17 species of fishes,
- 11 species of amphibians,
- 8 species of reptiles...
Various families of insects and other invertebrates have not yet been subject to these studies or inventories, and so this list is of course far from being exhaustive and will be extended in the years to come.
NB: in order to protect this abundance of species as best as possible, as well as the peace and quiet required for the fauna, access to the site is regulated and only possible during public opening hours.
