Species with regional biological responsibility in Brittany

The assessment of species from the point of view of Brittany’s biological responsibility for species is based solely on ecological criteria: abundance, distribution, trend, level of risk of extinction in the short term... Regulatory criteria (species listed by European directives, national decrees or decrees, etc.) or inventory criteria (znieff, scap, etc.) are not taken into account. The regional situation is compared to the national one. The taxa assessed are those for which the biogeographic information is most complete, including vertebrates. The lists will be completed as new knowledge is acquired. **Sources:** The observational data that enabled these assessments were acquired for the most part by the networks of volunteers organised around naturalist associations such as BV-Sepnb, GMB, Gretia, LPO, VivArmor Nature or the CBN Brest, BGM, the departmental federations of fishing or hunting, etc. Assessment by the regional flora observatories, led by the EPO (2015 - 2019) and validated by the CSRPN. **Go further:** consult the attached document "Regional Red List Methods and Biological Responsibility of Brittany" and the datavisualisation <a href="https://bretagne-environnement.fr/boardboard/evaluation-responsibility-biologique-regionale-especes-bretagne" target="_blank">"Evaluation of Brittany's regional biological responsibility for species"</a> carried out by the EPO.
