A species that exists only in the Crau

Endemic to the steppe grasslands of the Crau plainnear to Arles, the species has experienced a spectacular decline in the 20th century. Today, there are only three known sub-populations left:

  • a small relict population on seven hectares in Peau de Meau (National Nature Reserve of the Crau coussouls), the last in the centre of the Crau
  • two populations in the periphery of the Crau: one at Calissane (165 ha), straddling the Reserve and a military site, the other on the private BMW car testing site (85 ha).

It is listed as Critically Endangered on the global IUCN Red List and on the European Red List as well as on the French and Regional Red Lists. It is protected under French law.

To learn more about the Crau Plain Grasshopper, watch “A secret of the steppe”. This film was produced in 2019 by the animation studio Les Fées Spéciales supervised by the Conservatoire d’espaces naturels Provence-Alpes-Côte d’Azur and the Chamber of Agriculture des Bouches-du-Rhône, both co-managers of the Crau Coussouls National Nature Reserve. It was supported by the following partners: WWF-World Wide Fund for Nature, National Geographic Society, DREAL Provence-Alpes-Côte d’Azur, Conseil départemental des Bouches-du-Rhône and Carrière de la Menudelle.
