Causse de Sauveterre

History and Geology of the Causses

The Causses of Sauveterre, Méjean and Noir form part of the Grands Causses, situated in the southern part of the Massif Central. Separated by the Gorges du Tarn and the Gorges de la Jonte, this group of high plateaus offers fascinating landscapes and breathtaking views. Over the millennia, the River Tarn has carved a deep gorge between the Méjean and Sauveterre plateaus: a veritable canyon has been sculpted into the limestone massif of the Grands Causses. The River Jonte, meanwhile, separates the Méjean from the Causse Noir.

"A causse is a limestone plateau found in temperate regions, cut through by deep valleys – known as canyons – and featuring surface karst landforms (sinkholes, lapies)."

At an altitude of 1,000 metres, the Causse Méjean opens out into a vast steppe of yellow grass, as fascinating as any desert. Its landscapes, dotted with hamlets featuring their characteristic slate-roofed houses and shepherds’ huts, undulate endlessly. The Causse de Sauveterre is a less arid limestone plateau, with fairly rugged terrain in its south-western part.

In the Grands Causses, these high limestone plateaus, the flora consists mainly of wild thyme – known locally as ‘mountain thyme’ – sainfoin, white clover, sweet clover, bird’s-foot trefoil and sage. This diversity and the subtle blend of such varied scents generally give the honeys of the Causses a beautiful amber colour. Depending on where it was harvested, each honey possesses a unique range of aromas, faithfully reflecting the variety or varieties from which the bees gathered nectar.

Focus on agropastoralism

This is a sheep’s paradise! For indeed, the Grands Causses are also the realm of the sheep. There has always been a symbiotic relationship between the causses and the valley, between nature and the local people. Agropastoralism is proof of this: “the flocks graze on land – often difficult to mechanise – with varied vegetation: open grasslands, heathland or wooded pastures. These areas are characterised by their great heritage and environmental value, and by grazing, the flocks help to preserve habitats and species, and to maintain the landscapes and the local environment.”

2026 is the International Year of Pastoral Trails and Herders. The Causses and Cévennes Association is organising a number of events to mark this occasion. On the high plateaus, where the sheep once grazed, the cheese (Fédou, Lévejac and even Roquefort, depending on the milk collection area) and the free-range lamb have produced high-quality products. To gain a better understanding of the traditional way of life of the Causses people, you can visit the Causses Interpretation Centre at the Domaine des Boissets, or the Caussenarde d’Autrefois farm in Hyelzas.
