The Causses (French pronunciation: ​[kos]) are a group of limestone plateaus (700–1,200 m) in the Massif Central. They are bordered to the north-west by the Limousin and the Périgord uplands, and to the east by the Aubrac and the Cévennes. Large river gorges cut through the plateau, such as the Tarn, Dourbie, Jonte, Lot and Aveyron. Causse is an Occitan word meaning "limestone plateau". Arranged from the north-west to the south-east, the following plateaus are found: Many sites on the Causses are included in Natura 2000, notably the on the Larzac, Méjean, and Noir plateaus. * *
