    Description

    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 700,000 occurrences of 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. Standardized information regarding the occurrence's sex, reproductiveCondition, behavior, occurrenceRemarks, and samplingProtocol is included as well.

    Generalized and/or withheld information: since dataset v1.4 location information is no longer generalized to grid cells, but provided as the original decimalLatitude/Longitude and coordinateUncertaintyInMeters for all occurrences. Observer name, toponyms, and photographs are not included in the published dataset, but are known in the source database.

    Methodology

    Sampling

    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.

    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. The validation status is indicated in the field identificationVerificationStatus.
