The Atlas

Inter-municipal Biodiversity

The 2024-2031 management plan for the Grand Site de France Conca d'Oru, Patrimonio vineyard – Gulf of Saint-Florent aims to improve knowledge of the ecosystems and species present in its territory in order to better protect and promote them. It also aims to further study the interactions between biodiversity islands in wine-growing areas (Commitment 1.5.).

It is within this framework that the Joint Association of the Grand Site is now committed to achieving its Atlas of Municipal Biodiversity (ABC), a valuable tool for learning about and promoting local biodiversity.

What is an ABC?

inventory of habitats and species

A Biodiversity Atlas is an inventory of the environments and species present in a given territory, conducted in a participatory manner with the aim of involving all stakeholders in the territory (elected officials, citizens, associations, businesses, etc.) in the preservation of natural heritage.

This inventory makes it possible to map biodiversity issues at the local level, while providing municipalities with a tool for information and decision-making to better integrate biodiversity into their planning and management processes.

The approach

of the Grand Site de France

The Grand Site's ABC approach aims to enhance understanding of local biodiversity issues, in line with the specific landscape and cultural characteristics of the area. It responds to a desire on the part of the six municipalities in the area – Barbaggio, Patrimonio, Saint-Florent, Farinole, Poggio-d'Oletta and Oletta – as well as the Joint Association of learn more about natural habitats, fauna and flora present, of raise awareness among residents and visitors the natural resources of the territory and to support local economic stakeholders in taking biodiversity into account in their activities.

The Grand Site Biodiversity Atlas will be rolled out over three years, from 2025 to 2027. However, the data and actions resulting from this initiative, whether in terms of protection, promotion or awareness-raising, will continue well beyond 2027.

The Atlas is not limited to the perimeter of the Grand Site, but includes the entire perimeter of the six municipalities within its territory.

Why a Biodiversity Atlas?

at the level of the Grand Site de France?

The Grand Site de France stands out for the diversity of its landscapes. Agricultural plains, wetlands, rocky outcrops, wooded areas and coastline form a veritable mosaic of environments that are home to an exceptionally rich biodiversity that must be protected.

In fact, the Grand Site is of great ecological interest for:

The acquisition and dissemination of knowledge about these species and their habitats aim to reconcile biodiversity protection with human activities.

Natural habitats

Natural habitats with the proven presence of 24 habitats of Community interest, including 2 priority habitats.

Flora

The flora includes 131 heritage plant species listed in the bibliography, including one species of Community interest: the island cabbage of Barbaggio and Poggio d'Oletta.

Reptiles & Amphibians

Reptiles with habitats favourable to Hermann's tortoise, the European tree frog and the European pond turtle. Amphibians with the presence of the Sardinian discoglossid in temporary watercourses and the green toad.

Birds

Birds, with the presence of the red kite and the stone curlew in the open areas of the plain, and the potential presence of the peregrine falcon in rocky areas and the red-headed shrike in semi-open areas.

Chiroptera

Chiroptera with favourable habitats for hunting areas and locally proven roosts for species of high conservation value such as the lesser horseshoe bat, greater horseshoe bat and Geoffroy's bat.

Insects

Insects, including the Corsican zygene and four other insects of high heritage value that are dependent on open and semi-open environments (Corsican barbitist, Porto-Vecchio grasshopper, Corsican phaneropter and jas cricket), and the potential presence of the great capricorn beetle.

Project objectives

action plan

The Grand Site Biodiversity Atlas aims to work with all stakeholders to jointly develop a genuine action plan for local biodiversity.

Its purpose is to promote better everyone taking ownership of environmental issues : elected officials, local authority technicians, residents, schoolchildren, visitors and even economic stakeholders. The aim is for scientific knowledge to become shared, understood and integrated knowledge in daily practices and development projects.

The data collected during the inventories will form a reference base to feed into the local strategy biodiversity protection. They will also serve as a basis for land-use planning projects. Finally, they will be used to develop an awareness-raising initiative aimed at all audiences.

In conclusion, The overall objective of the ABC approach is to gain a better understanding of natural heritage and clearly identify biodiversity issues in the region. This effort should make it possible to protect and sustainably preserve fauna, flora and natural habitats, while reconciling ecological issues and human activities in the region.
