Abstract

Waarnemingen.be - Orthoptera occurrences in Flanders and the Brussels Capital Region, Belgium is a species occurrence dataset published by Natuurpunt. The dataset contains over 90,000 Orthoptera occurrences of 41 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.
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.
To allow anyone to use this dataset, we have released the data to the public domain under a Creative Commons Zero waiver (http://creativecommons.org/publicdomain/zero/1.0/). 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/ffwdxn) 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. We are always interested to provide more information or know how you have used the data, so please contact us via the contact information provided in the metadata or natuurdata@natuurpunt.be.
The publication of this dataset was supported by the INBO as part of the Flemish contribution to LifeWatch.

Taxonomic ranks
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Orthoptera
Common names: animals, insects, grashoppers & crickets

Spatial coverage

General spatial 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 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 3,536 meters using Wieczorek et al. (2004).
Coordinates: 50°40'12''N and 51°30'36''N Latitude; 2°31'48''E and 5°56'24''E Longitude 

Temporal coverage: August 1, 1920 - December 19, 2016

Methods

Method step description: Not provided.
Study extent description: See geographic coverage.
Sampling description: 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 majority of the data are presence-only data (absence data are not included in this dataset).
Quality control description: Recorded data are constantly verified by species group specialists (including professionals) 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. 13.9% of the observations in this dataset are supported by photographs on waarnemingen.be. The validation status is indicated in the field identificationVerificationStatus, the link to the original record in references.
