Réserve naturelle géologique de Haute-Provence

Created in 1984 by decree, the geological reserve of Haute-Provence covers an area of ​​200 hectares between the Alpes de Haute-Provence and the Var. It concerns the Digne thrust sheet, the pleated arch of Castellane, the Digne-Valensole basin and the Provencal Var links. It protects and enhances geological sites, fossils in place, landscapes with folded and fractured layers.
The protection is based on two scales of limits. On the one hand, a set of 18 geological sites on which the extraction and collection of any fossil form are prohibited. On the other hand, a vast protection zone extended over 59 municipalities where the extraction of fossils is prohibited and the collection of naturally released forms is tolerated, if practiced in limited quantities. Among the geotopes highlighted, we can mention the ammonite slab of Isnards in Digne, the fossiliferous ichthyosaur sites of La Robine or the sirenian site of the Tabori ravine in Taulanne.
