National nature reserve and associated protection perimeter in the Loiret

A national nature reserve and its associated protection perimeter are part of the protected natural areas (ENPs) that are designated or managed within an international, community, national or local framework with a view to achieving specific natural heritage conservation objectives. A national nature reserve is a protected land or marine area, created by the State, and whose natural heritage is exceptional, both in terms of biodiversity and sometimes in terms of geodiversity. A classification as a national nature reserve takes place to ensure the conservation of this exceptional heritage. It is a highly regulated space, exempted from any artificial intervention likely to degrade it and which benefits from a management plan. It is classified as Ia, III or V of IUCN (according to the regulations and management objectives put in place). Several national nature reserves benefit from an additional area in a “buffer zone” protected by this scheme. Depending on the case, one distinguishes between the perimeters of protection sensu stricto taken by prefectoral decree, and the protection zones defined by decree. Protection perimeters can be broad and defined from a list of municipalities, especially in the case of geological reserves.
