The modernisation of the ZNIEFF (Natural Areas of Ecological, Faunistic and Floristic Interest) at the national level is carried out on a continuous basis, allowing to have recent data and launch updates if necessary. In Auvergne-Rhône-Alpes, following the revision of the lists of critical species of terrestrial mammals, chiroprae, amphibians, reptiles and birds validated in late 2018, inventories are needed in order to update the data on these faunistic groups in type 1 NIEFFs on the basis of presence/absence with information on biological status if possible. For the departments concerned, this represents: — 34 ZNIEFF for chiropractic plants – 39 ZNIEFF for other mammals – 101 ZNIEFF for birds – 45 ZNIEFF for reptiles – 106 ZNIEFF for amphibians This 3-year work will be entrusted to a contractor chosen by call for tenders.
