Biodiversity

Exceptional ecological wealth

The Grand Site de France Conca d'Oru, Patrimonio vineyard, Gulf of Saint-Florent, is distinguished by its exceptional ecological richness, both terrestrial and maritime. This remarkable biodiversity is protected through several measures: Natura 2000 sites, Marine Nature Park, Atlas of Municipal Biodiversity.

FAUNA AND FLORA

Miscellaneous assets

The Grand Site area encompasses many different environments, favourable to a variety of heritage fauna and flora.

Among reptiles, there are habitats suitable for Hermann's tortoise, the European tree frog and the European pond turtle. Amphibians are well represented, notably including the Sardinian discoglossid (Sardinian toad) and the Green Toad.

The area is distinguished by its rich birdlife. The red kite (Milvus milvus) is regularly observed there, as is the Stone Curlew in the open areas of the plain. Rocky areas may be home to the Peregrine Falcon, while the Red-headed Shrike may be present in semi-open areas. The Sardinian Warbler (Sylvia undata) and the Sardinian Warbler (Sardinian warbler) are also among the protected species at the site.

In the territory, bats find varied hunting grounds, and proven roosts have been identified for several species of high heritage value, such as the lesser horseshoe bat (Hipposideros rhinolophus), the Greater Horseshoe Bat and the Geoffroy's Bat.

Open and semi-open environments are home to several remarkable insects, including the Corsican Zygene and the Corsican Swallowtail (Papilio hospiton), as well as the Corsican Barbitist, the Porto-Vecchio Decticella, the Corsican Phaneroptera and the Jasmine Cricket. The potential presence of the Great Capricorn beetle, a protected species, further enhances the site's entomological interest.

As for flora, 131 heritage plant species are listed in the bibliography, including one species of Community interest: the island cabbage (Brassica insularis) of Barbaggio and Poggio d'Oletta.
The rich flora is also evident in the remarkable diversity of orchids, such as Ophrys conradiæ, named after the Corsican botanist Marcelle Conrad, Ophrys funerea and Ophrys zonata, both endemic to Corsica and Sardinia and very rare, and Anacamptis papilionacea, Neotinea lactea and Serapias lingua.
Other emblematic heritage species such as the tree spurge (Euphorbia dendroides), sea lavender (Lavatera maritima) and oleander (Nerium oleander) illustrate the diversity of Mediterranean habitats present.

NATURA 2000 SITES

ECOLOGICAL RISKS AND CONTINUITY

Natura 2000 sites aim to preserve rare or endangered habitats and species in Europe. The Grand Site territory includes three Natura 2000 sites. The Grand Site now manages two of these Natura 2000 sites: Stations à chou insulaire and Strette de Saint-Florent. 

This is one of five sites in Corsica designated for the preservation of the island cabbage (Brassica insularis), a rare plant species that is globally endangered and of heritage and agronomic interest (as a reservoir of resistance genes for cultivated cabbages).

Composed of rocky ridges and limestone cliffs, the «strette» are conducive to specific biodiversity and constitute a habitat of Community interest.

These remarkable coastal and marine areas (dunes, scrubland, Posidonia seagrass beds) are home to a wealth of habitats. The marine section is part of the Cap Corse and Agriate Marine Nature Park.

MARINE NATURE PARK

CAP CORSE AND AGRIATE

Created in 2016 (6,830 km²), it partially covers the marine territory of the Grand Site.

It protects rare habitats (seagrass beds, coralligenous reefs) and heritage species (red lobster, dentex, lobster, bluefin tuna, yellowtail, swordfish, cetaceans, seabirds such as Audouin's gulls, crested cormorants, Cory's shearwaters and ospreys).

In cooperation with all stakeholders in the region and public policy makers, the Park ensures a balance between environmental and economic issues in its maritime territory.
It fulfils three fundamental objectives:

These objectives are broken down into six strategic priorities:

The large Mediterranean spider

The large Mediterranean spider (Maja squinado), is a species found on all types of seabed, whether sandy or rocky, or even in Posidonia seagrass beds. This crustacean, whose carapace can measure up to 25 cm, is most often observed between the surface and a depth of 50 m, but it is not uncommon to find it at greater depths. Did you know that this species is an expert in the art of camouflage? Young spider crabs use their claws to catch algae, sponges, molluscs and small anemones, which they attach to their shells. Highly prized for its taste, the spider crab is making a comeback along our coasts, where it is rising from the depths. If you are lucky enough to come across one, remember that only professional fishermen are authorised to catch this species.

Sea urchins

Fishing for sea urchins is highly regulated and controlled. To ensure that we can continue to enjoy this delicate but fragile delicacy, the Park conducts scientific monitoring work with the Stella Mare research platform. Twice a year, divers conduct counts at eight sites in the Park, at different depths, to obtain an accurate picture of the purple sea urchin population and be able to organise the sustainable management of this resource in partnership with professional fishermen.

ATLAS

COMMUNAL BIODIVERSITY (ABC)

The Grand Site's ABC approach aims to strengthen understanding of local biodiversity issues, in close connection with the specific landscape and cultural characteristics of the area.

It responds to a desire on the part of the six municipalities and the Grand Site Joint Association to gain a better understanding of the fauna and flora present in their territory, to raise awareness among residents and visitors of the area's natural riches, and to support local economic actors in taking biodiversity into account in their actions. The Municipal Biodiversity Atlas will provide the Grand Site with a tool for the municipalities in the area, facilitating their commitment to the protection and preservation of local biodiversity.

The ABC Project

The ABC project does not stop at the boundaries of the Grand Site but includes the entire perimeter of the six municipalities involved in the Atlas project as a whole, namely: Barbaggio, Patrimonio, Saint-Florent, Farinole, Poggio-d'Oletta and Oletta. The work resulting from the ABC will enable local authorities to better take biodiversity issues into account in their projects.
