Description

Waarnemingen.be - Butterfly occurrences in Flanders and the Brussels Capital Region, Belgium is a species occurrence dataset published by Natuurpunt and described (v1.4) in Maes et al. (2016, https://doi.org/10.3897/zookeys.585.8019). The dataset contains close to 1.3 million butterfly (Lepidoptera excluding moths) occurrences of 69 naturally occurring species (native, vagrant or migrant species), recorded by volunteers (citizen scientists), mainly since 2008. Together with the dataset Maes et al. (2016, https://doi.org/10.15468/njgbmh), it represents the most complete overview of butterflies in Flanders and the Brussels Capital Region (north Belgium). The occurrences are derived from the database http://www.waarnemingen.be, hosted at the nature conservation NGO Natuurpunt in collaboration with Stichting Natuurinformatie. Standardized information regarding the occurrence's sex, lifeStage, behavior, occurrenceRemarks, and samplingProtocol is included as well.

Generalized and/or withheld information: location information is generalized to 5 x 5 km² Universal Transverse Mercator (UTM) grid cells. Observer name, exact XY-coordinates, toponyms, and photographs are not included in the published dataset, but are known in the source database.

We would appreciate however, if you read and follow these norms for data use (http://www.natuurpunt.be/normen-voor-datagebruik) and provide a link to the original dataset (https://doi.org/10.15468/ezfbee) whenever possible. If you use these data for a scientific paper, please cite the dataset following the applicable citation norms and/or consider us for co-authorship.

Sampling Description

Study Extent

See geographic coverage.

Sampling

The observations (species, date, location, observer) were recorded by volunteers (citizen scientists) at http://www.waarnemingen.be.

Quality Control

Recorded data are constantly verified by butterfly experts (including professional entomologists) 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. 10% of the observations in this dataset are supported by a photograph on waarnemingen.be. The validation status is indicated in the field identificationVerificationStatus, the link to the original record in references.

Taxonomic Coverages

The dataset covers 69 butterflies species (Lepidoptera excluding moths) observed in Flanders and the Brussels Capital Region, Belgium. It includes 50 of the 69 native species, 3 regular migrants (Colias crocea, C. hyale, and Vanessa cardui) and 2 new-native species that are breeding in Flanders (Brenthis daphne and Pieris manni). 5 species (Aporia crataegi, Boloria selene, Coenonympha tullia, Fabriciana adippe, and Speyeria aglaja) no longer have breeding populations in Flanders and recent observations are all considered as vagrant individuals in this dataset. The Satyrium pruni observations are probably introduced. The remaining 8 species are vagrants that most likely spontaneously reached Flanders (Apatura ilia, Brenthis ino, Cupido argiades, Iphiclides podalirius, Lampides boeticus, Lysandra coridon, Nymphalis xanthomelas, and Pontia daplidice). Nomenclature is according to Fauna Europaea (https://fauna-eu.org/).

Geographic Coverages

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 grid cells of 5 x 5 km² of the Universal Transverse Mercator (UTM) coordinate system, 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 3,769 meters using Wieczorek et al. (2004). The coordinateUncertaintyInMeters is larger than the expected 3,536 meters due to an unknown geodetic datum being used for older observations.
