A Zone naturelle d'intérêt écologique, faunistique et floristique (Natural area of ecological, faunal and floristic interest), abbreviated as ZNIEFF, is a type of natural environment recognized by France. The inventory of a ZNIEFF area is an inventory of natural resources and scientific program launched in 1982 by Minister of Environment Huguette Bouchardeau and confirmed by the Act of July 12, 1983 called the Bouchardeau act. A ZNIEFF is not a measure of regulatory protection, but an inventory. It corresponds to the census of outstanding natural land areas in the twenty-two metropolitan areas as well as the overseas departments of France. The designation of a ZNIEFF based primarily on the presence of species or groups of species with strong heritage interest. The presence of at least one population of critical species (:fr:espèce déterminante in French) defines a ZNIEFF. This is one of the bases for prioritizing natural heritage issues as part of the National Biodiversity Strategy, or Regional Biodiversity Strategies, National Strategy for creation of protected areas (SCAP), etc. It is used for environmental impact assessment. The Belgian equivalent of the ZNIEFF is the Site of Great Biological Interest (SGIB). The program was launched in 1982 by the Direction de la protection de la nature (Department of Conservation) (now Direction de la nature et des paysages (Department of Nature and Countryside) of the Ministry of Ecology, Sustainable Development and Energy, with the support of the French National Museum of Natural History; The goal of this undertaking was to produce an inventory for the entire country, areas of greater ecological interest "primarily from the perspective of the Department provide a tool for decision support" (translated).
