Protected Spaces — ZNIEFF2 Perimeter — Dunkirk Urban Community

A natural area of ecological, faunistic and floristic interest, abbreviated by the acronym ZNIEFF, is an inventoried natural space due to its remarkable character. The ZNIEFF inventory is a naturalistic and scientific inventory programme launched in 1982 by the Ministry responsible for the environment and confirmed by the Law of 12 July 1983. A ZNIEFF is not a regulatory protection measure such as listed or listed sites, but an inventory. The inventory programme identifies the remarkable natural areas of land in the 13 metropolitan regions and the overseas departments. The designation of a ZNIEFF is based primarily on the presence of species or associations of species of high heritage interest. The presence of at least one population of a determining species makes it possible to define a ZNIEFF. It is one of the bases for prioritising natural heritage issues, the National Biodiversity Strategy, the Regional Biodiversity Strategies, SCAPs (National Strategy for the Creation of Protected Areas), etc. It is used in particular for impact assessments and environmental assessment Type II ZNIEFFs are generally important geographical ensembles, often including several Type I ZNIEFFs, and which designate an extended natural set whose general balances must be preserved. This concept of equilibrium does not, therefore, preclude a type II area from being subject to certain developments, subject to respect for general ecosystems.一类具备生态、动物区系与植物区系保护价值的自然区域，缩写为ZNIEFF，此类区域因具有显著特征而被纳入官方普查名录。 ZNIEFF普查是一项兼具自然保护学研究与科学严谨性的普查项目，由环境主管部门于1982年发起，并经1983年7月12日的法律正式确认。 ZNIEFF并非如保护名录或法定保护地那般属于法规性保护措施，而是一项普查认定名录。该普查项目负责识别法国本土13个大区及海外省境内具有极高自然价值的陆地自然区域。ZNIEFF的认定主要依据具有高遗产价值的物种或物种群落的存在，只要存在至少一个关键物种种群，即可划定为ZNIEFF区域。 该普查成果是自然遗产议题优先级划定、国家生物多样性战略、区域生物多样性战略以及SCAP（保护区创建国家战略，英文全称为National Strategy for the Creation of Protected Areas）等工作的核心依据之一，尤其可用于项目影响评估与环境影响评价。 II类ZNIEFF通常为规模可观的地理集合体，往往包含多个I类ZNIEFF区域，指代需要维护整体生态平衡的连片自然区域。因此，这一生态平衡的概念并不排斥II类区域在遵循生态系统整体保护要求的前提下开展适度开发活动。
