List of certain indicator species in Brittany

Various projects carried out in Brittany have led to the identification of species meeting certain criteria: species subservient to a single large type of environment at the scale of Brittany and species particularly sensitive to the fragmentation of environments in Brittany.

Sources: The observational data that enabled these assessments were acquired for the most part by volunteer networks organised around naturalist associations such as BV-Sepnb, GMB, Gretia, LPO, VivArmor Nature or the CBN Brest, BGM, departmental federations of fishing or hunting, etc. Assessment by regional flora observatories, led by the EPO (2018) and validated by the CSRPN.
