UK Environmental Change Network (ECN) bird data: 1995-2015

Bird species data from the UK Environmental Change Network (ECN) terrestrial sites. Counts of individual bird species are recorded. These data are collected, using the British Trust for Ornithology (BTO)'s Breeding Bird Survey methodology, at all of ECN's terrestrial sites using a standard protocol. They represent continuous records from 1995 to 2015 (the transects are walked twice each year). ECN is the UK's long-term environmental monitoring programme. It is a multi-agency programme sponsored by a consortium of fourteen government departments and agencies. These organisations contribute to the programme through funding either site monitoring and/or network co-ordination activities. These organisations are: Agri-Food and Biosciences Institute, Biotechnology and Biological Sciences Research Council, Cyfoeth Naturiol Cymru - Natural Resources Wales, Defence Science & Technology Laboratory, Department for Environment, Food and Rural Affairs, Environment Agency, Forestry Commission, Llywodraeth Cymru - Welsh Government, Natural England, Natural Environment Research Council, Northern Ireland Environment Agency, Scottish Environment Protection Agency, Scottish Government and Scottish Natural Heritage.

本数据集源自英国环境变化网络（UK Environmental Change Network, ECN）的陆地监测站点，记录了各鸟类物种的个体数量。
所有ECN陆地站点均采用标准规程，并遵循英国鸟类学信托基金会（British Trust for Ornithology, BTO）的繁殖鸟类调查方法开展数据采集工作。
该数据集涵盖1995年至2015年的连续观测记录，每年会对调查样线进行两次徒步遍历。
ECN作为英国长期环境监测计划，是由14个政府部门与机构组成的联盟资助的多机构协作项目。
各参与方通过为站点监测或（和）网络协调活动提供经费支持，助力该计划的开展。
参与该计划的机构包括：农业食品与生物科学研究所、生物技术与生物科学研究委员会、威尔士自然资源署（Cyfoeth Naturiol Cymru）、国防科学与技术实验室、环境、食品与农村事务部、环境署、林业委员会、威尔士政府（Llywodraeth Cymru）、英格兰自然署、自然环境研究委员会、北爱尔兰环境署、苏格兰环境保护署、苏格兰政府以及苏格兰自然遗产署。
