Species with regional stakes in Brittany

Species with regional conservation challenges have been identified in Brittany. They meet various criteria: threat of extinction, poor conservation status, high responsibility, etc., all of which are assessed at the regional level. The main file lists all Breton species with regional issues, including those using Breton marine waters or foreshore. It contains information detailing each of the articles of association: regional red list, regional conservation status, relative numerical representativeness, regional biological responsibility, European directives, national red list and determining species znieff. 2 files are associated with this list: * The first file presents the list of species with regional stakes for each of the communes of Brittany, based on observations compiled within the Biodiv'Bretagne platform and which are less than 20 years old. It does not take into account species of strictly marine ecology when they frequent Brittany. * The second file shows the density of municipalities in Brittany: for each municipality, the number of these species with regional stakes seen at least once has been established. This assessment is associated with the level of completeness of the communal list of all observed species. The synthesis is based on observations compiled within the Biodiv'Bretagne platform and which are less than 20 years old. It does not take into account species of strictly marine ecology when they frequent Brittany. **Sources:** Biodiv Bretagne. **Processing and shaping:** Environment Observatory in Brittany, with a regional collective work, bringing together naturalist experts, scientists and regional observatories fauna and flora (ORFF), as part of the regional declination of the Protected Areas Strategy, April 2024. **Go further:** consult the methodology and sources detailed in the datavisualisation <a href="https://bretagne-environnement.fr/boardboard/densite-especes-enjeux-regionaux-bretagne-terrestre" target="_blank">"Species at regional stake for terrestrial Brittany"</a> carried out by the EPO as well as the platform <a href="https://data.biodiversite-bretagne.fr/" target="_blank">Biodiv'Bretagne</a>.
