Ad hoc checklist of alien species in Belgium

The Ad hoc checklist of alien species in Belgium is a species checklist dataset published by the Research Institute of Nature and Forest (INBO). It was specifically created for the TrIAS project (Tracking Invasive Alien Species, http://trias-project.be) to account for gaps in the alien species coverage in other species checklists for Belgium and mainly includes taxonomic groups and newly introduced species not covered elsewhere (yet). Due to its ad hoc nature, the list might change substantially over time. Here it is published as a standardized Darwin Core Archive and includes for each species: the scientific name, higher classification and stable taxon identifier (in the taxon core), the (confidence regarding the) presence of the species in Belgium (and its regions), the date of first introduction and last assessment (in the distribution extension), coarse habitat information (in the species profile extension), the pathway(s) of introduction, native range(s) and invasion stage in Belgium (in the description extension), and an overview of the consulted literature for each taxon (in the literature references extension). Issues with the dataset can be reported at https://github.com/trias-project/ad hoc-checklist We have released this dataset to the public domain under a Creative Commons Zero waiver. We would appreciate it if you follow the INBO norms for data use (https://www.inbo.be/en/norms-data-use) when using the data. If you have any questions regarding this dataset, don't hesitate to contact us via the contact information provided in the metadata or via [e-mail]. This dataset was published as open data for the TrIAS project (Tracking Invasive Alien Species http://trias-project.be, Vanderhoeven et al. 2017), with technical support provided by the Research Institute for Nature and Forest (INBO). It is selected as one of the authoritative sources for the compilation of a unified and reproducible checklist of alien species in Belgium.比利时外来物种临时清单（Ad hoc checklist of alien species in Belgium）是由自然与森林研究所（Research Institute of Nature and Forest，INBO）发布的物种清单数据集。本数据集专为TrIAS项目（Tracking Invasive Alien Species，http://trias-project.be）打造，旨在填补比利时其他外来物种清单在物种覆盖范围上的空白，主要收录尚未被其他清单纳入的分类类群与新引入物种。鉴于其临时构建的特性，该清单后续可能会发生较大变动。 本数据集以标准化的达尔文核心档案（Darwin Core Archive）格式发布，每条物种记录包含以下信息：分类单元核心模块中的学名、高级分类阶元与稳定分类单元标识符；分布扩展模块中的物种（及其所属区域）在比利时的存在置信度、首次引入日期与最新评估时间；物种概况扩展模块中的粗略生境信息；描述扩展模块中的引入路径、原生分布范围及该物种在比利时的入侵阶段；以及参考文献扩展模块中各分类单元所参考的文献概览。若发现数据集存在相关问题，可前往https://github.com/trias-project/ad hoc-checklist 提交反馈。 本数据集已通过知识共享零许可协议（Creative Commons Zero）释放至公共领域。使用本数据集时，敬请遵循INBO的数据使用规范（https://www.inbo.be/en/norms-data-use）。若对本数据集存在任何疑问，可通过元数据中提供的联系方式或发送邮件至[e-mail]与我们取得联系。 本数据集由自然与森林研究所（INBO）提供技术支持，作为TrIAS项目（Tracking Invasive Alien Species，http://trias-project.be，Vanderhoeven等，2017）的开放数据发布。该数据集已被选为编制比利时统一且可复现的外来物种清单的权威来源之一。
