Great Crested Newt - Risk Zones (Cheshire)

This dataset identifies areas where the distribution of great crested newts (GCN) has been categorised into district zones relating to GCN occurrence and the level of impact development is likely to have on this species. Red zones contain key populations of GCN, which are important on a regional, national or international scale and include designated Sites of Special Scientific Interest for GCN. Amber zones contain main population centres for GCN and comprise important connecting habitat that aids natural dispersal. Green zones contain sparsely distributed GCN and are less likely to contain important pathways of connecting habitat for this species. White zones contain no GCN. However, as most of England forms the natural range of GCN, white zones are rare and will only be used when it is certain that there are no GCN.

本数据集旨在识别大口蟾蜍（GCN）分布区域，并将这些区域划分为与GCN出现相关及发展活动可能对该物种产生影响的行政区域。红色区域包含GCN的关键种群，这些种群在区域、国家或国际层面具有重要价值，并包括为GCN指定的特殊科学兴趣地。琥珀区域是GCN的主要种群中心，包含对自然扩散至关重要的连接栖息地。绿色区域GCN分布稀疏，该物种在此区域中不太可能包含重要的连接栖息地途径。白色区域不含GCN。然而，由于英格兰大部分地区是大口蟾蜍的自然分布范围，白色区域极为罕见，仅在使用时确信该区域无GCN时才会使用。版权声明：© 自然英格兰[年份]，经自然英格兰许可复制，http://www.naturalengland.org.uk/copyright/。© 英国王室版权及数据库权利[年份]。基于LCM2015 © NERC（CEH）[年份]。包含军用地形数据 © 英国王室版权[年份]，许可证号100017572。包含由自然环境研究理事会提供的数据 © NERC（生态与水文中心）。包含或源于军用地形数据提供的信息。© 英国王室版权及数据库权利[年份] 军用地形数据100022021。
