Beautiful, Elusive Eurasian Wolf: A Colourful Summer

Large predators symbols of a thriving region  

Lynx and wolves: key players in the natural balance of the mountains

The presence of large predators is evidence that the environment in the region remains wild and functioning. As apex predators, these species play a vital role in regulating ecosystems. Their continued presence in an area is a strong indicator of the quality of natural habitats and the richness of the wildlife.

Discreet and often little-known, the Eurasian lynx and the grey wolf play a vital part in the ecological dynamics of the forests and mountains of the Pays d’Évian and the Abondance Valley.

Spotlight on the Eurasian lynx, the elusive lord of the forests

Larger than a cat, the lynx stands between 50 and 75 cm at the withers and can be over a metre long. Its grey-brown coat speckled with black, its long, powerful legs and its tufted ears make it easily recognisable… if you’re lucky enough to catch a glimpse of it.

Solitary and extremely elusive, it inhabits forests and mountainous areas. It is mainly active at night and can cover a vast hunting territory, spanning up to several hundred square kilometres.

It kills around sixty roe deer or chamois a year, which is still a very small number compared with other causes of mortality affecting these animals. Extremely patient, with keen hearing and a highly developed sense of smell, the lynx can wait several days along a prey’s usual route before pouncing.

A protected species in France, the lynx was reintroduced into the Swiss Alps, the Jura and the Vosges between the 1970s and 1990s. It plays a key role in regulating animal populations and helps maintain the balance of forest ecosystems.

Hide and seek

The presence of a lynx can be detected by the clues it leaves behind: hairs left on the wood when it rubs against it, claw marks on tree trunks, and above all its droppings and footprints – the easiest clues to find and identify. Lynx footprints resemble those of a cat, but are two to three times larger. They’re even easier to spot in the snow!

Warning: lynx crossing!

This is a first for Haute-Savoie. In 2025, the CCPEVA installed road signs, supplied by the Athénas centre, to alert motorists to the presence of the Eurasian lynx. Over the past decade or so, lynx have been killed in road collisions, and the loss of even a single lynx could jeopardise the survival of the species in Haute-Savoie, where it is very rare.

It is a very secretive, solitary species that requires vast territories, which makes monitoring its population very difficult.

Although a few individuals are occasionally photographed by camera traps across the Chablais region, or signs of the species’ presence are found, it is impossible to draw any conclusions about whether the species is established in the area or about the number of individuals.

Males cover very long distances during the rutting season, and the few individuals observed may simply be passing through.

The Eurasian lynx is a species sensitive to even the slightest disturbance: human activity in natural habitats, roads and villages can act as significant barriers to its establishment.

The presence of the Eurasian lynx – and, more broadly, of large predators – serves as a reminder that the Chablais mountains remain a living environment capable of supporting a wildlife population with high ecological demands.

Fragile and elusive, these animals require vast, undisturbed areas in which to settle permanently. Protecting them calls for greater scientific understanding, appropriate management measures and a carefully considered coexistence between human activities and wildlife.

Preserving large predators means preserving the natural balance of an entire food chain and upholding the ecological richness of the region.

As part of the Contract for Sensitive Natural Areas (CTENS), the CCPEVA is working to improve our understanding of the lynx in the region. To this end, it is implementing measures for monitoring, raising awareness (International Lynx Day, film screenings, the installation of road signs, etc.) and preserving habitats that are favourable to the species within the region.
