NDFF Amphibian monitoring program 2001

The monitoring program primarily focuses on areas where key species occur. However, the development of common species in these areas can also provide important additional information.
We therefore follow all amphibians in areas where key species live, including common varieties. Data about all species is collected during field visits. The monitoring program supplies information about the current state of and changes to amphibian populations in the Netherlands in collaboration with Statistics Netherlands (CBS).

监测程序主要关注关键物种分布区域。然而，这些区域常见物种的发展亦能提供额外的、具有重要价值的信息。因此，我们跟踪所有生活于关键物种所在区域的物种，包括常见种类。在实地考察过程中，收集了关于所有物种的数据。监测程序与荷兰统计局（CBS）合作，提供关于荷兰两栖动物种群当前状况及其变化的详细信息。数据集可通过以下链接获取：https://www.ndff.nl/english / serviceteamndff@natuurloket。记录中包含非零的积极观察结果。截至2018年3月，共有101,808条记录。监测荷兰两栖动物的NDFF协议详情请参阅：https://www.ndff.nl/overdendff/validatie/protocollen/1-201-monitoring-van-amfibieen-in-nederland-2001/。
