[DREAL LR] National nature reserve and associated protection perimeter in Languedoc-Roussillon

A national nature reserve and its associated protection perimeter are part of the protected natural areas (ENPs) which are designated or managed within an international, Community, national or local framework with a view to achieving specific objectives of conservation of the natural heritage.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 in categories 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. The perimeters of protection may be wide and defined from the point of view of a list of municipalities, particularly in the case of geological reserves.Legal references: Articles L332-1 to L332-27, R332-1 to R332-29, R332-47 to R332-48 and R332-66 to R332-81 of the code of the Environment.

__Origin__

Source of georeferencing: the name and the actuality of the geographical repository used to digitise the perimeters of RNN are entered by the fields SRC_GEOM and SRC_ANNEE of the data series N_ENP_RNN_S_ddd.Thematic source: Administrative, legal or contractual classification of the protected natural area. These acts are referenced in the alphanumeric table N_ENP_ACTE_RNN_ddd associated with this dataset
18/10/2011: Creation of RNN projects, enhanced protections, and perimeter of protection projects. Digitisation in the 1/2000th of the 3 new layers and of the RNNs.
05/09/2013: correction of CONAT rnn (3 parcels less)
23/09/2015: updating attributes

国家自然保护区及其相关保护边界，属于受保护自然区域（Protected Natural Areas，缩写ENPs）的组成部分，此类区域通过国际、欧洲共同体、国家或地方层级的框架完成划定与管理，旨在实现自然遗产保护的特定目标。
国家自然保护区是由国家设立的受保护陆地或海洋区域，其在生物多样性乃至地质多样性层面均拥有卓越的自然遗产价值。将区域划定为国家自然保护区，旨在保障这类卓越自然遗产的存续。该类区域属于严格管控空间，禁止任何可能造成退化的人为干预，并配有专门的管理计划。此类区域依据世界自然保护联盟（International Union for Conservation of Nature，简称IUCN）的Ia、III或V类标准进行分类，具体分类取决于现有法规与管理目标。
部分国家自然保护区还设有受该保护体系覆盖的额外“缓冲区”区域。根据具体情况，需区分由省长令划定的严格意义上的保护边界，与政令界定的保护区域。保护边界范围可较为宽泛，通常以所辖市镇清单作为划定依据，地质类保护区尤其如此。
法律依据：《环境法典》第L332-1至L332-27条、R332-1至R332-29条、R332-47至R332-48条以及R332-66至R332-81条。
