Département du Var, Région PACA.
The site is steep and composed of grey rock with red patina. We also note the presence of underwater caves. The sandy beaches stretch for 40 meters. There is also a river system is formed by three small coastal rivers: Reppe, Rayolet and Vallat du Bouchou. The high depths of the archipelago integrated within the limits of the ASPIM, are delimited in depth by the -30 m depth.
This area is unique both on the terrestrial and marine plane, especially in the marine part by the presence of a barrier reef of Posidonia oceanica, the presence of sandy and sandy detritus-bottom muddy gathering all the communities, the presence of the rocky under-marine marine habitats of coralligenous and intertidal rocky areas of the entire coastal line with the exception of sandy areas and gravel beaches. The species present are the sidewalks of Lithophyllum lichenoides, the photophilic seaweed belts at Cystoseira amantacea. The Marine Reserve brings together most of the habitats, biocenoses and remarkable species of the Mediterranean lower and sub-coastal areas. On the terrestrial side, it is an area that shelters beaches of sand and pebbles, halo-nitrophilic vegetations, shaved lawn in Allium chamaemoly, shrub including the Matorral arborescent with wild olive tree and lentisk and “Tamaris” of France formations.
The marine area around the Grand Rouveau is under threat of an increase in anthropogenic activities: tourism, yachting, artisanal/pleasure fishing, scuba diving. There are two main types of tourism, land tourism (visit to the Island) and recreational activities at sea. Both are based on activities that are mostly summer. This site presents a great vulnerability due to human pressure on marine resources already perceptible. The island itself is impacted by the presence of the plants that invades natural habitats to the detriment of local species. Uncontrolled attendance contributes secondarily to the destruction of certain species as well as the presence of introduced predators (black rats: Rattus rattus).
On the terrestrial faunistic level, the presence of the rare and threatened European phyllodactyle is mainly reported. In its marine part, the area contains remarkable habitats and protected species listed in Annexes II and III of the ASP/DB Protocol (Posidonia oceanica, Pinna nobilis, Cymodocea nodosa, Lithophyllum, etc.). The terrestrial part (island) of Grand Rouveau offers various ecological potentials, whose steep terrain and soil conditions are satisfactory, fostered by the presence of regular plant cover and the excellent conservation status of the marine environment by the presence of diverse and high-quality marine habitats promoting underwater wealth.

Owned by the Conservatoire du littoral since 2000, the island of Grand Rouveau is managed by the city of Six-Fours with the support of the APIR (Association de Protection de l'Ile du Rouveau). Since 2001, it has had a first document of study of the terrestrial environment and summary recommendations of management, carried out at the time of its acquisition by the Conservatoire. The management plan was carried out by a team of international experts within the framework of the initiative «Petites Iles de Méditerranée». It was validated by a local management committee. The DOCOB Natura 2000 «Lagune du Brusc» completes this management plan for its marine part. It was carried out by the Paul Ricard Oceanographic Institute and was approved by the Steering Committee in December 2010.
The Ile du Grand Rouveau is located in the vicinity of the municipality of Sixfours-les-Plages in the Var. It is the westernmost island in the Embiez archipelago and is 650 metres from the island of Embiez (the archipelago’s main island), and 1.23 nautical miles from the coast.
