Waarnemingen.be - Non-native plant occurrences in Flanders and the Brussels Capital Region, Belgium
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 502,000 occurrences of 1,618 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.

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 143,497 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

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.
|Bounding Coordinates||South West [50.67, 2.53], North East [51.51, 5.94]|
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.
|Kingdom||Plantae (plants), Fungi (mushrooms), Chromista|
|Start Date / End Date||1862-06-30 / 2021-07-02|
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. The validation status is indicated in the field identificationVerificationStatus.|
