UK Biodiversity Indicator C3b, Status of UK species of European importance

This spreadsheet is the underlying data for the biodiversity indicator C3b, Status of UK species of European importance.

Article 17 of the European Union Habitats Directive requires Member States to report every six years on progress made with maintaining and/or restoring favourable conservation status for habitat types and species of community interest. These are habitats and species for which the UK has European-level conservation responsibilities.

Details of exactly what information is to be delivered is laid out in the report format and guidance notes. Each assessment needs to conclude whether the species is in one of the following states:
- Favourable
- Unfavourable-Inadequate
- Unfavourable-Bad
- Unknown

However, it is likely to take time before species move from unfavourable conservation status to favourable conservation status, so for the unfavourable assessments, an assessment of trend is made to determine if the species is improving, declining, or stable.

This is one of a suite of 24 UK biodiversity indicators published by JNCC on behalf of Defra; the latest publication date was 19 January 2016 - for indicator C3b the latest data are for 2013. The supporting technical document details the methodology used to create the indicator.

本电子表格构成了生物多样性指标C3b，即英国物种欧洲重要性的现状的底层数据。根据欧盟栖息地指令的第17条，成员国需每六年报告一次在维护和/或恢复栖息地类型和社区利益物种的有利保护状况方面取得的进展。这些栖息地和物种是英国承担欧洲级保护责任的领域。具体应提供何种信息的细节已在报告格式和指导说明中阐述。每次评估均需得出结论，判断物种是否处于以下状态之一：
- 有利
- 不利-不足
- 不利-恶劣
- 未知
然而，物种从不利保护状况过渡到有利保护状况可能需要一段时间，因此对于不利评估，会进行趋势评估，以确定物种是改善、恶化还是保持稳定。这是由JNCC代表英国环境、食品和农村事务部（Defra）发布的24个英国生物多样性指标之一；最新的出版日期为2016年1月19日——对于指标C3b，最新的数据为2013年。支持的技术文件详细说明了创建指标所使用的方法。
