Biodiversity in Saint-Tropez

Exceptional biodiversity

The Saint-Tropez coastline and its natural environment are part of a Mediterranean ecosystem with exceptional biological diversity. Between the turquoise waters of the Gulf of Saint-Tropez and the unspoiled coastal paths, the region is a sanctuary for marine and terrestrial flora and fauna.

This remarkable biodiversity is the subject of protection and awareness programs run by local institutions, associations, and sea users.

Among the best practices for 2025: the port of Saint-Tropez is fighting invasive species and is committed to banning pesticides and herbicides to preserve local flora and biodiversity.

Coastal trails, guardians of our environment.   The coastal paths, from Saint-Tropez to Ramatuelle, preserve the diversity of the Mediterranean’s natural heritage while raising public awareness.   Informative signs and educational initiatives accompany walkers on topics such as:   Preserving coastal ecosystems, Respecting flora and fauna, Preventing the risks of fire and pollution.

See on Sea: observing and protecting the sea

With See on Sea, you can track marine biodiversity in real time, report sightings of species, and contribute to participatory science on local flora and fauna.

It’s a great way to raise awareness among sea users and strengthen environmental consciousness.

Natural wealth

Saint-Tropez is home to exceptional biodiversity, both on land and at sea, which makes our region unique. Between fragrant scrubland, pine forests bathed in sea air, and unspoiled seabeds, each environment is home to unique species that must be protected.
