The Catalogue of Life infrastructure, ChecklistBank, serves as a repository (‘data catalogue’) for taxonomic, nomenclatural, and other species list data sources, like national or policy relevant and legal species lists. In this milestone report, work by Catalogue of Life is reported for two tasks. For task 2.1.2, an overview is provided of the relevant invasive species lists and national species list already mediated through Catalogue of Life’s ChecklistBank. For task 2.2.2b, work is reported on the mobilisation and publishing of the EU Directives open species data in Catalogue of Life’s ChecklistBank. Catalogue of Life ChecklistBank mediates (partial) national species lists originating from 26 of the 27 European Union Member States. Several countries have multiple lists that can be considered as partial national lists, and that are not merged into one national species reference list. There are 52 invasive species lists published from Europe as open data in ChecklistBank. Again, some countries publish multiple invasive species lists, and not necessarily one unified list for the entire country. The corpus of available open species data originating from national and/or invasive species lists in Catalogue of Life’s ChecklistBank is already very high. These data are available for use in the Biodiversity Meets Data project, and free to use for Natura 2000 site managers.
