Press release

Posted on November 19, 2020

The Department of Environment and Security (DES) is launching a public inquiry into the decision to classify Bois de Chênes on the territory of the municipalities of Genolier and Coinsins. This document supplements the regulations in force in the Bois de Chênes and updates the inclusion of federal inventories for the protection of nature and the landscape. It also provides clarifications, in particular with regard to the reception of the public and the uses of the site. This revised classification will provide a real long-term protection strategy for this exceptional natural and landscaped site.

The Bois de Chênes, which extends over nearly 140 hectares at the foot of the Jura between the villages of Genolier, Coinsins, Begnins, Vich and Arzier-Le Muids, presents a very wide variety of natural environments and is home to a remarkable amount of rare and protected species. It is bordered by a high quality agricultural and wine-growing landscape. The site has enjoyed protection since 1966, when the State of Vaud classified it in order to prevent the creation of a shooting range. This decree then established in the heart of the Bois de Chênes estate an integral and scientific reserve and a perimeter of prohibition of military exercises.

The sector has many biotopes, many of which have been registered since 2007 in federal inventories. Also a landscape site of national and cantonal importance, the Bois de Chênes has been home to a mixed forest reserve of some 100 ha since 2015.

A revision of the 1966 classification decree was deemed necessary to integrate the issues of protecting the various inventories. By specifying the routes that can be taken as well as the fire places or reception areas for the classes, it also aims for better cohabitation between site users. The DES therefore puts the decision to classify Bois de Chênes to the public inquiry from November 20 to December 19, 2020.

Three distinct sub-perimeters

The documents put to the public inquiry maintain three distinct sub-areas within the territory of the communes of Coinsins and Genolier. They confirm the vocation of an integral and scientific reserve given to some 36 ha of the Bois de Chênes in the heart of the massif. Left to its free evolution and a haven of tranquility for wildlife, this sub-perimeter is only accessible to pedestrians, without dogs and on a limited number of paths.

It is bordered by a second perimeter comprising a little over 90 ha of open access forests and meadows of high biological value. Places for the reception of classes as well as places where it is allowed to make fires are also provided in this sub-perimeter. The third sub-perimeter, planned for the communes of Coinsins and Genolier, is intended as a landscape protection zone between the reserve itself and the more densely populated areas.

Collaboration with the various actors

The classification decision put to the public inquiry was drawn up by the cantonal services in collaboration with the municipalities as well as with the main stakeholders concerned. The Cantonal Commission for Nature Protection and the Federal Office for the Environment were also able to comment on it. The revised classification will provide a real strategy for the long-term conservation of this exceptional site while ensuring its access to the public.

The investigation is open from November 20 to December 19. The entire file can be viewed by appointment at the offices of the communes of Genolier (022 366 11 62) and Coinsins (022 364 35 35). The documents will also be submitted to the General Directorate for the Environment of the State of Vaud, Biodiversity and Landscape Division, ch. du Marquisat 1, 1025 St-Sulpice, by appointment only (021 557 86 30). The file is also available on the website of the State of Vaud at
