Waarnemingen.be - Plant occurrences in Flanders and the Brussels Capital Region, Belgium

Latest version published by Natuurpunt on Sep 21, 2018 Natuurpunt

Waarnemingen.be - Plant occurrences in Flanders and the Brussels Capital Region, Belgium is a species occurrence dataset published by Natuurpunt and described (v1.4) in Steeman et al. (2017, https://doi.org/10.3897/phytokeys.85.14925). The dataset contains close to 1.2 million plant occurrences of almost 1,200 naturally occurring species (native, vagrant or migrant species), recorded by volunteers (citizen scientists), mainly since 2008. The occurrences are derived from the database http://www.waarnemingen.be, hosted at the nature conservation NGO Natuurpunt in collaboration with Stichting Natuurinformatie. Together with the datasets Van Landuyt & Brosens (2017, http://www.gbif.org/dataset/271c444f-f8d8-4986-b748-e7367755c0c1) and Van Landuyt & Noé (2015, https://doi.org/10.15468/xnlbke), the dataset represents the most complete overview of indigenous plants in Flanders and the Brussels Capital Region.

Generalized and/or withheld information: location information is generalized to 4 x 4 km² IFBL grid cells. Observer name, exact XY-coordinates, toponyms, and photographs are not included in the published dataset, but are known in the source database.

Geographic Coverage

Flanders and the Brussels Capital Region. These regions are situated in the north of Belgium and cover an area of 13,522 km² and 162 km² respectively (13,684 km² in total or 45% of the Belgian territory). Flanders is largely covered by agricultural land (51%), urban areas (30%) and woodland (10%) while the Brussels Capital Region mainly consists of urban areas (73%), woodland (12%) and other green areas (10%) (Vriens et al. 2011). All occurrence data are generalized to Instituut voor Floristiek van België en Luxemburg (IFBL) grid cells of 4 x 4 km², with the grid codes indicated in the field verbatimCoordinates. The WGS84 centroids of these grid cells are calculated in decimalLatitude/Longitude with a coordinateUncertaintyInMeters of 2,828 meters using Wieczorek et al. (2004).

Bounding Coordinates South West [50.67, 2.53], North East [51.51, 5.94]

Taxonomic Coverage

The datasets contains close to 1,200 naturally occurring vascular plant species (as well as a number of subspecies, varieties, forms, hybrids and multispecies) recorded in Flanders and the Brussels Capital Region. This includes angiosperms (flowering plants), gymnosperms, ferns and allies, but not algae, mosses and lichens. If the observer remarked that the specific individual of this native plant was introduced by man, then this is recorded in the field establishmentMeans. The taxonomic reference for the dataset is Heukels’ Flora of the Netherlands by Van der Meijden (2005) which follows the classification as suggested by the Angiosperm Phylogeny Group (APG II 2003).

Sampling Methods

Most observations (species, date, location, observer) were recorded by volunteers (citizen scientists). The dataset also includes historical records and datasets imported in waarnemingen.be. The large majority of records (95%) is a casual observation (presence only record). 5% of observations were registered as part of a species checklist. This is recorded in the field samplingProtocol.

Study Extent See geographic coverage.
Quality Control Recorded data are verified by a group of botanical experts (including professional botanists), based on collected specimens, the observer’s species knowledge, added photographs and known species list of locations. The validation procedure from waarnemingen.be consists of an interactive procedure in which observers can be asked for additional information by a team of validators, after which the validator manually adds a validation status. Manual validation focuses on rare species, species that are reported outside their known range and observations accompanied by pictures. Records that are not manually validated are additionally checked by an automated validation procedure that takes into account the number of manually validated observations of a species within a specified date and distance range. 13% of the plant records in this dataset are supported by photographs in waarnemingen.be. The validation status is indicated in the field identificationVerificationStatus, the link to the original record in references.

Additional Metadata

Purpose Plants have a long history of being recorded by both amateur and professional botanists. Volunteer data from amateur botanists were always an important source of distribution data of plants. The atlas of Flanders and the Brussels Capital region (Van Landuyt et al. 2006) was based on the teamwork of many volunteer botanists, NGOs, scientific institutes and governmental organisations. Since Natuurpunt, the largest nature conservation NGO in Flanders, Belgium, launched the web portal waarnemingen.be in 2008, the number of plant observations in Flanders and the Brussels Capital Region has risen sharply. Beside IFBL-mapping and project-related observations, this database is easily used for occasional observations and can be used for monitoring (wildlife) areas. Old notebooks and reports were screened and stored in the database (Steeman et al. 2012). The team of specialized validators motivates the inexperienced observers and validates observations. Here we publish these records on a IFBL (Instituut voor Floristiek van België en Luxemburg) grid cell resolution of 4 × 4 km².
