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, 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). meer

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).

This dataset was published as open data for the TrIAS project (Tracking Invasive Alien Species, 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.
Geographic coverage: This checklist covers species that are non-native in Belgium. The aim of the checklist is to provide information on species that are not (yet) covered by other checklists, so it is not meant to be comprehensive. For some taxa, information is included on its presence in Flanders, Wallonia and the Brussels Capital Region (the three main political regions in Belgium).
Taxonomic coverage: This checklist includes over 200 alien species from 4 kingdoms. Arthropods constitute the largest proportion of taxa, followed by spiders and mammals.
Sampling method: Data for this checklist are compiled by directly contacting specialists of underrepresented taxonomic groups and scanning online databases and published but unstandardized species checklists for alien species in Belgium. The dataset also includes information previously gathered for the state of biodiversity in Flanders (incl. De Bruyn 2005, De Bruyn et al. 2007, Dumortier et al. 2007 & 2008, Adriaens et al. 2010, Demolder et al. 2017). The checklist is managed in a Google Spreadsheet ( where we aim to collect to following information: for taxa: scientific name, higher classification, taxon rank, and nomenclatural code; for distributions: location, country (BE), occurrence status, first and last observation date, and degree of establishment; for species properties: native range, (standardized) introduction pathway and realm (terrestrial, marine, freshwater); and the source on which this information is based. Data are added and verified by different people.
