GCN - Strategic Opportunity Areas (Cheshire)

This dataset identifies areas where the addition of new ponds would benefit Great Crested Newt populations. The core areas contain a pond density of 2+ ponds and are located within a 1km square where great crested newt presence has been predicted. Fringe areas contain a pond density of 1 and are located within a 1km square where great crested newt presence has been predicted or are within a 250m of a Core Area. Higher scores are associated with darker colouration and represent a greater presence of suitable habitat features: grassland (+250m buffer), woodland (+250m buffer), within 100m-2500m range of a river, with a pH >6.5 and Phospherous >40. These suitable habitat features have been given a score of ‘1’. Arable land and Suburban areas have been given a score of ‘-1’. Urban areas greater than 2ha (+400m buffer), roads (7.5m buffer), rivers (+7.5m), Special Protection Areas (+500m), Special Areas of Conservation (+100m) and Ramsars (+100m) have been excluded.

本数据集旨在识别新增池塘将对大口蟾蜍种群产生益处的区域。核心区域池塘密度达到2个以上，并位于预测到大口蟾蜍存在的1平方公里区域内。边缘区域池塘密度为1，位于预测到大口蟾蜍存在的1平方公里区域内，或位于核心区域250米范围内。评分越高与颜色越深相对应，代表适宜栖息地特征（如草地、林地等）的出现越频繁：草地（+250米缓冲区）、林地（+250米缓冲区）、河流100米至2500米范围内、pH值大于6.5、磷含量大于40。这些适宜栖息地特征获得评分‘1’。耕地和郊区地区则获得评分‘-1’。超过2公顷的城区（+400米缓冲区）、道路（7.5米缓冲区）、河流（+7.5米）、特殊保护区（+500米）、特殊保护区（+100米）以及拉姆萨尔湿地（+100米）均被排除在外。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/。© 英国皇室版权和数据库权利2018。基于LCM2015 © NERC（CEH）2017。包含军用地形数据© 英国皇室版权2007，许可证号100017572。包含由自然环境和研究委员会提供的数据© NERC（生态与水文中心）。包含或派生自军用地形数据。© 英国皇室版权和数据库权利2018 军用地形数据100022021。
