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

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 (http://doi.org/10.3897/zookeys.585.8019). The dataset contains close to 900,000 butterfly occurrences of 68 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 dataset Maes et al. (2016, http://doi.org/10.15468/njgbmh), the dataset represents the most complete overview of butterflies in Flanders and the Brussels Capital Region (north Belgium). 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.
