Waarnemingen.be - Non-native plant occurrences in Flanders and the Brussels Capital Region, Belgium

Latest version published by Natuurpunt on Sep 21, 2018 Natuurpunt

Waarnemingen.be - Non-native plant occurrences in Flanders and the Brussels Capital Region, Belgium is a species occurrence dataset published by Natuurpunt and described (v1.2) in Swinnen et al. (2018, https://doi.org/10.3391/bir.2018.7.3.17). The dataset contains over 143,000 occurrences of 1,355 non-native plant, algae and fungi 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.

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 and urban areas while the Brussels Capital Region is mainly urban. 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 dataset contains all plant, algae and fungi taxa recorded in Flanders and the Brussels Capital Region which have the status naturalized, naturalizing, exotic, or incidental import in waarnemingen.be. This includes angiosperms (flowering plants), gymnosperms, ferns and allies, algae, mosses, lichens and fungi. This currently covers 1,351 plant, 2 Chromista and 2 fungi species (as well as a number of subspecies, varieties, forms, hybrids and multispecies).

Kingdom  Plantae (plants),  Fungi (mushrooms),  Chromista

Temporal Coverage

Start Date / End Date 1859-06-30 / 2016-12-31

Sampling Methods

The observations (species, date, location, observer) were recorded by volunteers (citizen scientists) at http://www.waarnemingen.be. The dataset also includes historical records and datasets imported in waarnemingen.be. The dataset is a mixture of presence-only data, checklists and monitoring data.

Study Extent See geographic coverage.
Quality Control Recorded data are constantly verified by a group of botanical experts (including professional botanists) taking collection specimens, the observer’s species knowledge, added photographs and known species list of locations into account. 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. Records that are not manually validated are additionally checked by an automated validation procedure that takes into account the number of manually validated observations within a specified date and distance range. 21.6% of the plant records in this dataset are supported by photographs on waarnemingen.be. The validation status is indicated in the field identificationVerificationStatus.
