the partias nature reserve, a refuge for the lpo
Comprising a wide variety of environments (rocks, lakes, wetlands, mixed forests, etc.) with great geological diversity, this reserve is the ideal place for many species to thrive. It is also home to a large number of insect species, protected and/or endangered plant species, and more.
To preserve this reserve, the inhabitants of the territory have mobilized to prevent certain developments and thus respect the richness of this valley.
theregional nature reserve of Partias
This reserve, near Briançon, was created thanks to a citizen initiative, the Association des amis des Combes (Friends of the Combes Association), which aimed to prevent development in the valley in order to protect biodiversity.
The LPO (League for the Protection of Birds) now manages the reserve in agreement with local residents and stakeholders. More than 104 species of birds and 524 species of plants live in the reserve. It is an important refuge for birdlife, particularly black grouse and rock ptarmigan.
It is also a place with a surprising variety of alpine landscapes, including rocks, lakes, wetlands, larch forests, and alpine moors. There are many hiking trails starting from Puy Chalvin . However, the Partias Nature Reserve is a protected, preserved, and regulated area.
In order to help preserve this protected area, it is important to comply with the regulations in place. These regulations enable human activities (hiking, mountain biking, pastoralism, etc.) to be reconciled with the preservation of biodiversity.

wintering area and raising awareness among hikers
At the end of winter, LPO teams set out in search of droppings, which helpidentify the wintering grounds of black grouse. This allows them to locate and protect these birds from skiers. Repeated passage by hikers can have serious consequences for their survival and reproduction. This is why protected areas are designated as "quiet zones" to avoid any disturbance. It is a way of raising awareness and educating people. It is mandatory to bypass the protected areas and keep your dog on a leash in the reserve in order to safeguard the species living in this territory. Exploring the reserve with a guide is the best way to avoid disturbance and to understand the importance of preserving this environment.
Pastoralism in the Partias Reserve
Pastoralism is present in the Partias reserve with 1,200 sheep and 76 cows. In the fall of 2023, eight watering troughs were installed to allow the herds to drink.
Pastoralism in the reserve is managed by the GAEC de Notre-Dame des Neiges, livestock farmers, shepherds, the AFP (Association Foncière Pastorale) and the two co-managers of the reserve.
This involves working in consultation with these various stakeholders to manage the herds while preserving the environment and biodiversity. Numerous studies have been and are being carried out to assess the effects of pastoralism on the site's biodiversity and the effects that climate change may have on food resources, and thus to observe how plant species adapt over time.
