Exotic plant occurrences in Wallonia is a merged occurrence-only dataset, compiling records of exotic taxa from various floristic data sources covering Wallonia (Southern Belgium). Data compilation, cleaning and validation were performed by the Département de l’Étude du Milieu Naturel et Agricole (SPW – DGARNE - DEMNA), in particular the 'GT-Flore', a working group bringing together plant experts from the department and external collaborators from regional naturalist networks.
The types of primary sources compiled in this dataset are heterogeneous, including specific surveys, citizen observations, digitized collections, etc. Attention should therefore be paid to the "DC term: collectionCode" when figuring out record features. Also, 'FootprintWKT' should be used preferably for spatial referencing, as the dataset includes both grid-derived and point data.
"Flore OFFH and Co" (120 000 records) is the core of the DEMNA database. It covers monitoring carried out by the department officers or by partners under agreement, data from digitization calls, etc.
"Observatoire Wallon des Ambroisies","BD Berce du Caucase", "Enquetes OFFH","Rinse", "Inv. Perm. des Res. For.","Natura 2000",are topical surveys, limited in time and/or taxonomically/spatially oriented.
All records have been subject to a validation procedure performed by the department experts. Validation rules were based on pictures, observer’s expertise, ecological relevance, or additional information provided by the observer.

Additional information is accessible upon specific and motivated request addressed to: http://observatoire.biodiversite.wallonie.be/cmdd/. Please contact the department for additional information about the dataset, about the Walloon 'GT-Flore', or about our biodiversity related activities. Returns and comments are highly appreciated.
Purpose
The dataset was published within the framework of the TrIAS project (Tracking Invasive Alien Species, Vanderhoeven et al. 2017 - http://trias-project.be) .The aim of TrIAS is to establish an open data framework to follow the progression of exotic species, identify emerging species, assess the risk and inform the IAS policies.
Sampling Description
Study Extent
Wallonia, southern Belgium. Some opportunistic data may be slightly out of the described area. This dataset includes data from different projects that may have very different time distributions: going from early 20th data recovered by digitizsation projects to early 2018 inputs into the department databases.Sampling
Multiple sources involving different types of data collection. The dataset encompasses citizen observations, expert prospection, digitized collection, published documents, etc.Quality Control
The validation was carried out by botanical experts from the department. Each validator is assigned to a list of taxa of his expertise and has access to corresponding records. The validation may be based on a document (picture), on rules (credibility of the occurrence, of the observer expertise, etc.) or without any document (additional informations provided by the observer). It is documented by the "DC-Term : IdentificationVerificationStatus". For the purpose of this publication, semi-automatic treatment has been applied to validate all records made by qualified observers. Records subject to this semi-automatic validation are flagged on the "DC-Term: IdentificationRemarks".Method steps
- Fusion of botanical data sources.
- Comparison & linkage of the different taxa with the reference used for exotic species (see 'taxonomic coverage' section).
- Semi-automatic validation based on observer's expertise.
- Mapping to Darwin Core.
