Discover why it is crucial to respect the Major Sensitivity Zones (ZSM) in Haute-Savoie to preserve the bearded vulture, an endangered species. Maps, dates, advice and an app to track bearded vultures.
Why ZSMs are vital for the bearded vulture
The bearded vulture, a majestic bird of prey found in the Alps, is one of Europe's most endangered species. With a wingspan of nearly 3 metres, it plays an essential ecological role by recycling carcasses, but its reproduction remains fragile: only one chick every 2 to 3 years. The slightest disturbance can cause the nest to be abandoned or the chick to fall. To limit these risks, the National Action Plan (PNA) has established Major Sensitivity Zones (ZSM) around nesting sites. These zones, which are active from November to August, aim to reduce human activities (hiking, climbing, free flight, motorised flight) near the nests. Respecting these zones guarantees the survival of the species and preserves Alpine biodiversity.

ZSMs in Haute-Savoie: Bornes and Aravis
In Haute-Savoie, several ZSMs are currently active for the 2025-2026 season. They cover the following areas in particular: Aravis Nord, Pierre Fendue, Aravis Sud (Manigod), Bargy, Sixt-Passy, Sixt-Fer-à-Cheval, Luzier, as well as Morzine 1 and 2 and Arclosan. These zones are marked out around nests known and monitored by ASTERS-CEN74. They are updated regularly: some will be deactivated in March if no pairs settle there. To view the complete map and download the GPS files (.KML, .GPX), consult the official ZSM maps. These perimeters are not legal prohibitions, but strong recommendations: compliance is essential to avoid breeding failure.
How to adapt your practices in the mountains
Whether you are a hiker, climber, paraglider or microlight pilot, your behaviour matters. In the core areas of the ZSMs, all activities are prohibited from 1 November to 31 August. In buffer zones, avoid noisy activities and respect flight distances: a minimum of 300 metres for non-motorised flights and 1,000 metres for motorised flights and drones. Outdoor sports enthusiasts are advised to consult maps before setting out. Information signs are installed at certain sites, but vigilance is still required. Photographers, please note: searching for ‘the perfect shot’ can cost a chick its life. Every action counts in maintaining the positive momentum of the population, which remains fragile despite reintroduction efforts.
Tools for tracking and protecting the bearded vulture
To find out more, download the app developed by ASTERS-CEN74 as part of the Birdski project. It allows you to track the movements of bearded vultures equipped with GPS and identify sensitive areas in real time. This app, available here, is a valuable tool for professionals and mountain enthusiasts. In addition, the gypaete-barbu.com website offers interactive maps and practical advice. Finally, share the awareness video, on your social media networks to inform your friends and family. Together, let's make Haute-Savoie an exemplary region for the protection of endangered species.
Best practices in ZSM
To protect the bearded vulture and respect Major Sensitivity Zones:
- Consult the ZSM maps before each outing: See maps
- Avoid all activities in core areas from 1 November to 31 August (hiking, climbing, free flight, drones, etc.)
- Respect flight distances:
- Minimum 300 m for non-motorised flights
- 1,000 m for motorised flights and drones
- Do not attempt to approach or photograph nests: disturbance can be fatal.
