The general objective of this contract is to carry out a diagnosis, evaluation and prioritization of ecological issues (fauna, flora and habitats) on the perimeter of the study likely to be impacted by the project. The service provider will have to collect data from the field (counting, identification, etc.) but also bibliographic data (database from the RAIN (Réseau des Acteurs de l'information Naturaliste) poles, CORINE biotopes, Cahiers d'habitats, etc. The data will cover fauna, flora and habitats. Whatever the inventory, it will be specified, for all species, the type of associated habitat, the population density by species, their ecology, their sociology, regulatory and heritage status, their rarity, their vulnerability, the locations (GPS point)

This diagnosis will consist of: - identifying and precisely locating sensitive natural areas or areas of ecological interest within the scope of the study; - take up the data available by the Réseau des Acteurs de l'information Naturaliste (Rain) and its poles; - identify possible wetlands; - carry out an inventory, fauna, flora and habitat of the study area on the basis of existing documentation (bibliography, data from the RAIN network, ZNIEFF and inventories, protected areas, Natura 2000 sites)
