GCN - Strategic Opportunity Areas (Derbyshire)
收藏资源简介:
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: pH 6-7 Distance from grassland <100m Density of grassland 5-67% Distance from woodland <100m Density of woodland 5-67% Shannon-Weaver diversity -2 to -0.8 These suitable habitat features have been given a score of ‘1’. Distance from arable land <250m Has been given a score of ‘-1’. Urban areas > 2ha (+400m buffer), roads (7.5m), rivers (7.5m) and Environment Agency Flood Zone 2 have been excluded.

本数据集用于识别可通过新增池塘惠及大冠蝾螈(Great Crested Newt)种群的区域。 核心区域的池塘密度为2个及以上,且位于已预测存在大冠蝾螈的1平方公里范围内。 边缘区域的池塘密度为1个,且处于已预测存在大冠蝾螈的1平方公里范围内,或距离核心区域250米以内。 分值越高,颜色越深,代表适宜栖息地特征的占比越高,相关适宜特征包括: pH值6~7; 距草地距离<100米; 草地覆盖率5%~67%; 距林地距离<100米; 林地覆盖率5%~67%; 香农-威弗多样性指数(Shannon-Weaver diversity)-2至-0.8。 上述适宜栖息地特征均被赋予分值“1”。 而距耕地距离<250米的区域则被赋予分值“-1”。 面积大于2公顷的城区(含400米缓冲带)、宽度7.5米的道路、宽度7.5米的河流以及英国环境署(Environment Agency)洪水风险区2级区域均已被排除。 归因声明: © 英国自然英格兰署(Natural England),2021年 基于LCM2015数据 © 英国国家环境研究委员会(NERC,生态与水文中心CEH)2011年。包含英国地形测量局(Ordnance Survey)数据 © 皇家版权2007年。 基于LCM2015数据 © 英国国家环境研究委员会(NERC,CEH)2017年。包含英国地形测量局数据 © 皇家版权2007年,授权编号100017572。 土壤数据 © 克兰菲尔德大学(Cranfield University,国家土壤资源研究所NSRI)及英国王室文书局局长2019年。 包含英国国家环境研究委员会(NERC,生态与水文中心CEH)及英国自然英格兰署提供的数据。 © 欧洲环境署(European Environment Agency),哥白尼计划(Copernicus Programme)2016年。 土壤数据 © 克兰菲尔德大学(NSRI)及英国王室文书局局长2020年。基于LCM2007数据 © NERC(CEH)2011年。包含英国地形测量局数据 © 皇家版权2007年。© 第三方授权方。包含或衍生自英国地形测量局及农村支付署(Rural Payments Agency)提供的信息。© 皇家版权及数据库权2020年。 © 淡水栖息地信托基金(Freshwater Habitats Trust),PondNet监测计划2018年。 © HS2有限公司,2020年。 安伯瓦利自治区议会 © 皇家版权及数据库权2021年,英国地形测量局100021321;博尔索弗区议会 © 皇家版权及数据库权2020年,英国地形测量局100019526;切斯特菲尔德自治区议会 © 皇家版权及数据库权2020年,英国地形测量局(0100018505);德比市议会 © 皇家版权及数据库权2020年;德比谷区议会 © 皇家版权及数据库权2020年;德比郡议会 © 皇家版权及数据库权2020年;东北德比夏区议会 © 皇家版权及数据库权2020年,英国地形测量局100019665;南德比夏区议会 © 皇家版权及数据库权2020年。 包含或衍生自英国地形测量局提供的信息。© 皇家版权及数据库权2020年,英国地形测量局100022021。 包含英国地形测量局数据 © 皇家版权及数据库权2020年。
