The Monitoring of invasive alien crayfishes in the Flemish part of the LIFE RIPARIAS areas is an event dataset published by Agency for nature and forests (Flemish government, Belgium). The data are collected from targeted monitoring on ponds within the nature areas managed by the Agency for nature and forests, in the summer of 2022. Only invasive species are presented in this dataset. The data are published as a standardized Darwin Core Archive and includes for each occurrence record an occurrenceID, date, location, quantification and scientific name. Issues with the dataset can be reported at https://github.com/riparias/anb-crayfishes-occurrences/issues We have released this dataset to the public domain under a Creative Commons Attribution License. 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.

An inventory was made of the alien macroinvertebrates occurring in Flanders. To this end large collections of biological samples were investigated and supplemented with own sampling campaigns. Mainly fresh and brackish surface waters were investigated. Three new macroinvertebrate species for Flanders were discovered. In total 41 alien macroinvertebrates were encountered in fresh and slightly brackish surface waters in Flanders. Additionally, 24 alien macroinvertebrate species have been reported for the Belgian part of the North Sea and its adjacent estuaries. Most alien macroinvertebrates belonged to the crustaceans and molluscs. Over 2,500 samples containing macrocrustaceans were identified to species level, which allowed us to accurately map their distribution in Flanders. Alien species found in the fresh and brackish water environment, mainly originated from the Ponto-Caspian area and North-America followed by Asia and South- and East-Europe. This overview shows that alien macroinvertebrates are widespread and abundantly present in many watercourses in Flanders. Based on observations in neighbouring countries, several additional species are expected to arrive in the near future. A follow-up of the invasive alien species together with a monitoring scheme to detect new incoming species is valuable to estimate the size of the problem and to be able to closely follow their ecological and economic impact This dataset was originally created for research on the spread and impact of alien invasive macroinvertebrate species in Flanders. However, the dataset can be reused for a variety of purposes. However, this being an occurrence dataset, it can be used for understanding species richness, distribution pattern and modelling studies such as ecological niche modelling. In order to enhance the confidence of use, we have documented the metadata as well as subjected the data records to a series of quality assessment and enhancement processes as described in the earlier section quality control description. To allow anyone to use this dataset, we have released the data to the public domain under a Creative Commons Zero waiver (http://creativecommons.org/publicdomain/zero/1.0/). We would appreciate however, if you read and follow these norms for data use (http://www.inbo.be/en/norms-for-data-use) and provide a link to the original dataset (https://doi.org/10.15468/xjtfoo) whenever possible.

The Inventory of alien macroinvertebrates in Flanders, Belgium is a species checklist dataset published by Ghent University. It contains information on 73 alien macroinvertebrate species (mostly crustaceans and molluscs) occurring in Flemish aquatic habitats, from inland lakes to coastal harbours at the North Sea. The inventory is the result of the study Boets et al. (2016) (https://doi.org/10.3391/ai.2016.11.2.03 with occurrence data at https://doi.org/10.15468/xjtfoo) where it was originally published as supplementary material. 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 year of first introduction and last assessment in Flanders (given as a year range in the event date in the distribution extension), coarse habitat information (in the species profile extension) and the pathway(s) of introduction, native range(s), and invasion stage in Flanders (in the description extension). The dataset can be used for researching and managing aquatic invasions or compiling regional and national registries of alien species. Issues with the dataset can be reported at: https://github.com/trias-project/alien-macroinvertebrates We have released this dataset to the public domain under a Creative Commons Zero waiver. We would appreciate it if you follow the GBIF citation guidelines (https://www.gbif.org/citation-guidelines) 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 https://twitter.com/trias_project. 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.
