Method steps

1. The source data for this standardized checklist is an Excel sheet, originally published as Table S1 in the supplementary material of Zieritz et al. (2014) (https://neobiota.pensoft.net/article/4007/list/5/).
2. This raw data file was uploaded to a GitHub repository (https://github.com/trias-project/rinse-registry-checklist). See https://trias-project.github.io/rinse-registry-checklist for an introduction to this repository and the mapping of this dataset.
3. We developed a RMarkdown script to document and perform the transformation of the data to Darwin Core, which includes the following steps:
4. Perform some basic cleaning of the raw data and scientific names.
5. Generate stable and unique identifiers for each taxon (taxonID).
6. Create a taxon core file (http://rs.gbif.org/core/dwc_taxon.xml), with information about the higher classification.
7. Create a distribution extension file (http://rs.gbif.org/extension/gbif/1.0/distribution.xml), including the interpretation of occurrences for each country (translated into occurrenceStatus and establishmentMeans).
8. Create a species profile extension file (http://rs.gbif.org/extension/gbif/1.0/speciesprofile.xml), with coarse habitat information.
9. The resulting Darwin Core data files are uploaded to the INBO IPT and documented with metadata.
10. The dataset is published and registered with GBIF.

The checklist incorporates a wide variety of non-native taxa present in the Two Seas Area and aims to be non-biased towards particular countries or taxa. It includes 6.643 unique taxa, with 6.661 distribution statements per country (duplicates are the result of multiple sources for the same taxon). The checklist covers five kingdoms: Plantae (3.643), Animalia (2.698 taxa), Fungi (199 taxa), Chromista (96 taxa) and Bacteria (3 taxa) and 31 phyla. Additionally, 3 viral taxa were recorded.

1. Plantae
   rank: kingdom
2. Animalia
   rank: kingdom
3. Fungi
   rank: kingdom
4. Chromista
   rank: kingdom
5. Bacteria
   rank: kingdom

The checklist covers species that are non-native in at least one of the four countries (Great Britain, France, Belgium and the Netherlands) comprising the Two Seas Programme area (https://www.interreg2seas.eu/en/content/programme-area), and includes terrestrial, marine and freshwater habitats. This region includes various geological types, ranging from Pre-Cambrian, to Carboniferous, Cretaceous and Tertiary rocks. The main river systems in the area include the Thames, Loire, Meuse and Rhine.
