Plateau de Canjuers is a high karstic plateau in southeastern France notable for its extensive limestone plateaux, strategic location, and restricted public access due to military use. Located in Provence-Alpes-Côte d'Azur near the border of Var and Vaucluse, it lies within the cultural region of Provence and the biogeographic zone of the Alps. The plateau has long been a crossroads between the Luberon, the Vaucluse Massif, and the Verdon Gorge corridor.

Geography

The Plateau de Canjuers occupies terrain between Drôme-linked alpine foothills and Mediterranean lowlands near Nice, bounded by the Luberon to the west and the Montagne de Lure to the north. Its topography includes karstic dolines, poljes, and dry valleys opening toward the Durance River and the Verdon River. Administratively it touches communes such as Aups, Riez, Sainte-Tulle, Les Salles-sur-Verdon, and Castellane and lies within the historical provinces of Comtat Venaissin and County of Provence. Road access connects with the D900 and routes leading to Manosque, Draguignan, and Forcalquier.

Geology and Ecology

Geologically the plateau is part of the Alpine orogeny system and is composed primarily of Jurassic and Cretaceous limestones, featuring karst phenomena similar to the Causses and the Vaucluse Plateau. Sinkholes, caves, and perched springs reflect recharge into subterranean networks studied by speleologists from institutions like the Muséum national d'Histoire naturelle and the CNRS. Soils are thin over carbonate bedrock, resembling those on the Plateau du Vercors and influencing vegetation patterns comparable to the Monts de Vaucluse and Dentelles de Montmirail.

History

Human presence on the plateau dates to prehistoric periods evidenced by artifacts comparable to finds from the Lascaux region and Mesolithic sites in Provence. During antiquity the area lay within the territory of Gaule Narbonensis and later the Roman Empire, with nearby Roman roads linking Apt and Riez to the network that included Arles and Marseille. Medieval history ties the plateau to feudal holdings of the Counts of Provence and later to administrative units within the Kingdom of France. In modern times the plateau figured into strategic considerations during the Franco-Prussian War era and the two World War II campaigns in the French Riviera hinterland.

Military Use and Canjuers Military Camp

Since the early 20th century much of the Plateau de Canjuers has been occupied by the Canjuers military camp, established by the French Army and associated with units based in Marseille, Toulon, and Istres. The camp was expanded after World War II and used for maneuvers by brigades originating from École spéciale militaire de Saint-Cyr graduates and regiments like the 1st Parachute Chasseur Regiment. Its range facilities and training grounds have hosted NATO exercises involving contingents from United States Army Europe, the British Army, and other NATO partners. The presence of the camp has influenced land tenure similar to military zones like the Camp de Souge and the Camp of Les Éparges, with restricted access enforced by the Direction générale de l'armement and the Ministry of the Armed Forces.

Biodiversity and Conservation

Despite military use, the plateau supports habitats akin to those protected in Parc naturel régional du Verdon and the Parc naturel régional du Luberon, including steppe-like grasslands, Mediterranean scrub comparable to the garrigue of Bouches-du-Rhône, and calcicole plant communities reminiscent of Calanques National Park flora. Notable species recorded on or near the plateau include raptors such as the Bonelli's eagle and European honey buzzard, mammals paralleling populations in Mercantour National Park like the red fox and wild boar, and reptiles similar to those in Camargue salt marsh fringes. Conservation interest has prompted studies by organizations including Ligue pour la Protection des Oiseaux and collaborative monitoring with the Office national des forêts.

Economy and Human Activity

Traditional economic activities around the plateau include pastoralism and transhumance routes linked culturally to Camargue and alpine shepherding traditions, with sheep and goat grazing patterns similar to those on the Causses. Local agriculture in adjacent communes produces products associated with Provence gastronomy such as olives, lavender, and wine from vineyards of the Côtes de Provence appellation. Military presence has generated employment tied to logistics and maintenance in towns like Draguignan and Aups, while regional planners from entities such as Conseil régional de Provence-Alpes-Côte d'Azur and Conseil départemental du Var manage land-use issues.

Tourism and Recreation

Public access is limited compared with tourist destinations like the Gorges du Verdon and the Luberon villages; nonetheless, viewpoints along peripheral roads offer panoramas appreciated by visitors to Moustiers-Sainte-Marie and Sainte-Croix-du-Verdon. Outdoor activities in surrounding areas include hiking on trails near Mont Ventoux routes, cycling stages used in events like the Tour de France, and canyoning in neighbouring gorges popularized by guides from Aix-en-Provence and Nice. Cultural tourism connects to nearby heritage sites such as Abbaye de Sénanque, Palais des Papes, and museums in Aix-en-Provence.
