Protective measures


The area surrounding the Tattes-de-Bogis is protected by a number of protective measures at the Federal level because the zone is home to a unique biodiversity and an important historical heritage.

Find out more below about the various inventories that are already in-place to protect the site.

Federal inventories

The area surrounding the Tattes-de-Bogis site is listed in a number of inventories:

Wildlife protection

  • The Tattes-de-Bogis are located on the cantonal reserve of fauna n°23 ( la réserve cantonale de faune n°23 ​) housing a priority nesting area for birds (Skylark) and a breeding and feeding zone essential for many animal species (beavers, hares, batrachians, etc...)
  • The site is also particularly important for the conservation of fish life: trout breed here, as do grayling and sculpin.
  • The Tattes-de-Bogis are also located on a biological corridor of European, supraregional and national importance (corridor biologique d’importance européenne, suprarégionale et nationale ​)  that is the main crossing point for deer coming down from the Jura in winter.

​ ​

  • In addition, also included in a cross-border action plan for Europe and Switzerland are two priority forest for the amphibian species that can be found at the Tattes-de-Bogis: the Agile Frog and the Yellow-bellied Sounder.

Historical importance

The future landfill site is adjacent to two monuments of Cantonal historical renown:

  • The Grilly  bridge (protected site, Note 2) –

 Recensement architectural du canton de Vaud Fiche 30.  ​

  • The Swiss-French border post Nº 308 (protected site, Note 3) –

 Recensement architectural du canton de Vaud Fiche 32.   ​


Downstream and beyond

The area downstream of the river is listed in the Federal Inventory of Landscapes, Sites and Natural Monuments of National Importance (IFP).
And in France: 

  • The Upper Versoix and Brou marshes are classified under Natura 2000.
  • The cross-border flow of the Versoix river is classified as a natural area of ecological, faunistic and floristic interest (ZNIEFF).
  • The Versoix marshes are classified as a ZNIEFF.
  • The Bidonnes and Prodon marshes are classified as remarkable wetlands.



Landfill risks and threats


In view of global warming and recurring water stress, it is important to preserve our shared water resources. 
And yet...

Water Quality

  • The landfill site will be located less than 100 metres from the river and will be situated above the Versoix river over a distance of 2 kilometres. The removal of the 45 hectares of agricultural land that links the Versoix woodland to the Bois de Portes could have dramatic consequences for the hydrological balance of the region. With a downhill gradient of between 16 and 18 metres, run-off water from the entire landfill area would flow straight into the Versoix marshes and the river, with a high probability of chemical pollution.
  • This will be exacerbated by the dust generated by the toing and froing of the lorries offloading their cargo, the mechanical excavotors and wind picking up the dust.
  • This pollution could end up in Lake Geneva, which provides an important source of our drinking water...
  • And ironically, the Versoix river and its surroundings have undergone significant regeneration and renaturing work designed to improve water quality.

Wildlife issues

Remember that the river and its surroundings provide:

  • an important wildlife corridor.
  • a refuge for protected species (frogs, beavers) and a nesting area for priority species (skylark).
  • home to valuable fish (lake trout, grayling, sculpin).
  • a popular area for outdoor activities like walking, cycling and horse-riding.
