Natural Area of Ecological Interest Type 1 Faunistic and Floristic 2nd generation in the Centre-Val de Loire region

Geographical delimitation of the Natural Areas of Ecological Faunistic and Floristic Interest (ZNIEFF) type 1 second generation updated or created as part of the ZNIEFF inventory modernisation programme initiated in 1995. The purpose of the ZNIEFF inventory is to identify and describe areas with high biological capacity and good conservation status. There are 2 types of ZNIEFF:* Type I ZNIEFF: areas of major biological or ecological interest;* Type II ZNIEFFs: large, rich and unmodified natural ensembles, offering significant biological potential.本数据集为1995年启动的具有动植物区系生态价值的自然区域（Natural Areas of Ecological Faunistic and Floristic Interest，简称ZNIEFF）名录现代化项目中更新或新建的第二代第一类ZNIEFF的地理边界。ZNIEFF名录的核心目标是识别并描述具备高生物承载能力与优良保护现状的自然区域。ZNIEFF共分为两类： * 第一类ZNIEFF：具有重大生物或生态价值的自然区域； * 第二类ZNIEFF：规模庞大、物种丰富且未受人为干扰的自然复合生态系统，具备显著的生物潜能。
