One of the aims of the project is to restore the lakes of community importance at the Chambaran Military Camp.

Initial study (Action A1)

The initial study is essential to ensure that practical restoration and conservation activities are carried out effectively. It will involve analysing the lakes in general, as well as focusing specifically on the fauna (molluscs, coleoptera, odonata, etc.) and associated flora.

The species and habitats listed in Annex 2 of the Habitats Directive and the remarkable species (included on the red lists) will be studied in close detail.

The inventories will cover eight lakes on the military camp and one pond. The first chain of lakes is located to the north and includes the Étang de la Femme, the Étang des Meuniers, the Étang des Bécassines, the Étang des Nénuphars and the Étang des Sans-soucis.  The second chain is located to the south and includes the Petit Étang de Vienne and the Grand Étang de Vienne. The pond, on the Ferme des Lilas, is located not far from these. There is also a single lake in the west, the Étang de Chazal Garnier.

Restoration of the lakes (Action C1)

The lakes will be restored in accordance with the results of the initial study (Action A1). The plans involve:

  • Installing a drain box at the outlet of one lake and restoring an embankment (leak)
  • Cutting down birch woodlands (not of community importance)
  • Reshaping the bank to reclaim lake shores

The aim is to halt the advancing vegetation that is colonising the key habitats on the lake shores (code 3130 and 3150) and to restore regular water coverage on these shores. The aquatic plant communities on the shores are short, thinly spread grasses that have developed as a result of the humidity gradient on the shallow inclines and temporary land emergence. As well as restoring habitats of community importance, the work will also encourage remarkable and/or protected species to colonise the sites.
