Observations.be - Orthoptera occurrences in Wallonia, Belgium
Latest version published by Natagora on 17 September 2020 Natagora

Observations.be - Orthoptera occurrences in Wallonia, Belgium is a species occurrence dataset published by Natagora. The dataset contains over 35,000 occurrences of 46 occurring species, recorded by volunteers (citizen scientists), mainly since 2008. The occurrences are derived from the database https://observations.be, an initiative from the nature conservation NGO Natagora (https://www.natagora.be) in collaboration with Stichting Natuurinformatie and Natuurpunt. Standardized information regarding the occurrence's sex, lifeStage, behavior, occurrenceRemarks, and samplingProtocol is included as well.

Generalized and/or withheld information: for some occurrences, location information is generalized to grid cells, as requested by the observer (usually to avoid disturbance or collecting). Observer name, 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 (https://www.natagora.be/donnees_naturalistes_usage) and provide a link to the original dataset 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 Methods

The observations (species, date, location, observer) were recorded by volunteers (citizen scientists) at http://www.observations.be. The dataset is a mixture of presence-only data and checklists.

Study Extent See geographic coverage.
Quality Control 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 observations.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, the link to the original record is in references.
