Article 12 Birds Directive Reporting 2008-2012 Dataset Series

The Birds Directive (Directive 2009/147/EC) came into force in Ireland in 1981. Article 12 of this directive requires Member States to report on the implementation of national provisions taken under this Directive including specific reporting on status and trends of bird species. The first new format Article 12 report was submitted by member states in 2014 covering the four year period 2008 – 2012 inclusive. The Eionet website provides access to the information contained in all the national reports - see http://bd.eionet.europa.eu/article12/. The reports include a separate report for each individual bird species. If the particular report is describing a breeding population then a breeding distribution and range map forms part the report. Detailed distribution data was primarily derived from the 2007-11 Bird Atlas (via BirdWatch Ireland) but also from species specific projects conducted by NPWS and others. Final 10km and 50km grid mapping was generated from this information by NPWS and by Birdwatch Ireland. The resources referenced in this metadata relate to these distribution and range mapping for breeding populations in Irish National Grid. The individual species reports on the Eionet website provide important information on the sources and selection of data to derive the final distributions and ranges. All enquires on detailed distributions should first be directed to BirdWatch Ireland. NPWS is in a position to release the 10km (and 50km where appropriate) derived grid distribution data. Details of the Article 12 the related reporting requirements, including reporting format guidance and reference portal are available at http://ec.europa.eu/environment/nature/knowledge/rep_birds/index_en.htm. The following Data Resources are included in this download, and detailed metadata is available for each resource in the download: - AR1212_CurrentDistributionAllSpecies.shp - Multipart polygon shapefile showing the national distribution of the all reported breeding bird species. The national grid distributions for the 135 individual species are largely based on the national distributions for these species generated by Birdwatch Ireland for the BirdAtlas2007 to 2011. - AR1212_CurrentRangeAllSpecies.shp Multipart polygon shapefile showing the national range of the all 135 reported breeding bird species. Range "...describes roughly the spatial limits within which the habitat or species occurs.《鸟类指令（Directive 2009/147/EC）》于1981年在爱尔兰正式生效。该指令第12条要求欧盟成员国汇报本国根据本指令制定的法规执行情况，其中需包含鸟类物种现状与趋势的专项报告。 成员国于2014年提交了首份采用新格式的第12条报告，覆盖2008年至2012年的完整四年周期。欧洲环境信息网络（Eionet）网站提供了所有国家报告的查阅入口，具体网址为http://bd.eionet.europa.eu/article12/。 每份报告均针对单个鸟类物种单独编制。若某份报告聚焦于某物种的繁殖种群，则需附带繁殖分布范围地图作为报告的组成部分。 详细的分布数据主要源自2007-2011年《爱尔兰鸟类图集》（由爱尔兰观鸟协会BirdWatch Ireland提供），同时也参考了国家公园与野生动物服务局（NPWS）及其他机构开展的物种专项调查项目。NPWS与BirdWatch Ireland基于上述信息最终生成了10km与50km分辨率的网格制图成果。 本元数据（metadata）所关联的资源，均为爱尔兰国家网格框架下的繁殖种群分布与范围制图数据。 Eionet网站上的单个物种报告，详细说明了用于生成最终分布与范围数据的资料来源与筛选标准。 所有关于详细分布数据的咨询，应首先联系BirdWatch Ireland。NPWS可提供10km（适用场景下含50km）分辨率的网格分布数据。 第12条报告的相关报送要求（包括报告格式指南与参考门户）的详细信息，可查阅网址http://ec.europa.eu/environment/nature/knowledge/rep_birds/index_en.htm。 本次下载包含以下数据资源，每份资源均配有详细元数据： - AR1212_CurrentDistributionAllSpecies.shp —— 多部件多边形形状文件（shapefile），展示所有已上报繁殖鸟类物种的全国分布情况。本次收录的135个单个物种的国家网格分布数据，主要基于BirdWatch Ireland为2007至2011年鸟类图集生成的对应物种全国分布数据。 - AR1212_CurrentRangeAllSpecies.shp —— 多部件多边形形状文件（shapefile），展示135种已上报繁殖鸟类物种的全国活动范围。 “范围（Range）”指“物种或其栖息地大致分布的空间边界。
