Great Crested Newt - Risk Zones (North Somerset and South Gloucestershire)

This dataset identifies areas where the distribution of great crested newts (GCN) has been categorised into 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. Attribution statement: © Natural England, 2022

本数据集旨在识别大口吻蝾螈（GCN）分布区域，并将GCN的分布划分为与GCN出现相关及发展对这一物种可能产生影响的区域。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意义，并包括为GCN指定的具有特殊科学兴趣的地点。琥珀色区域包含GCN的主要种群中心，并构成了有助于自然扩散的重要连通生境。绿色区域分布着稀疏的GCN种群，且不太可能包含该物种重要的连通生境路径。白色区域不含GCN。然而，由于英格兰大部分地区是大口吻蝾螈的自然分布范围，白色区域极为罕见，仅在确定无GCN存在时才会使用。归属声明：© 自然英格兰，2022
