An area of mainly dry calcareous grassland with sclerophyllous scrub, and old orchards. The main land-uses are extensive traditional sheep-farming; and growing almonds and olives.
This is the only large semi-arid plain in France, and supports important populations of typical steppe breeding species.
Pressure/threats to key biodiversity
The site is seriously threatened by: the cultivation and modification of steppe-meadows; the use of irrigation; the felling of old almond and olive orchards and their replacement with commercial groves; the leasing out of military training areas for agricultural exploitation; disturbance from recreational activities and hunting; plans to build a motorway. These changes seriously threaten the populations of Tetrax tetrax, Burhinus oedicnemus and Pterocles alchata.
