Waarnemingen.be - Orthoptera occurrences in Flanders and the Brussels Capital Region, Belgium is a species occurrence dataset published by Natuurpunt. The dataset contains over 125,000 grasshopper and cricket (Orthoptera) occurrences of 42 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. Standardized information regarding the occurrence's sex, lifeStage, behavior, occurrenceRemarks, and samplingProtocol is included as well. 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.

The Saltabel dataset deals with grasshopper and cricket occurrences in Belgium. The data are largely gathered by volunteer naturalists, who also reviewed and digitised data from existing museum and university collections in Belgium. Input in a database, feedback to observers, validation and database maintenance were cared for by a professional employee at the Institute for Nature Conservation (IN). The Saltabel (Salta < Saltatoria; bel > Belgium) working group was established in 1989. The purpose of this project was mainly to collect information about the distribution, faunistics and ecology of grasshoppers and crickets in Belgium, The Netherlands and Luxembourg. The working group produced a newsletter which appeared irregularly in the period 1989-2002 with the intention to inform observers about latest findings, interesting observations, ecological research etc., provide feedback to naturalists and to raise awareness about the conservation value of Orthoptera in general. During this periode, the working group was most active and organised annual weekends, in turn organized in Belgium, the Netherlands and sometimes also northern France . These weekends were intended to perform inventories for badly prospected regions and to stimulate knowledge exchange between collaborators. In 1997, a standard work on the grasshoppers and crickets of The Netherlands was published using data from this project (Kleukers et al. 1997). In 2000, a provisional atlas and red lists of grasshoppers and crickets in Flanders , Brussels and Wallonia was published (Decleer et al. 2000), providing the first major output of this faunistic project for Belgium. As a consequence, the interest for grasshoppers and crickets in conservation increased, as these insects became important indicators of natural quality and successful nature management. After this milestone, the working group lost some incentive, the network of volunteers was no longer professionally supported and Saltabel became less active. In 2006, a dedicated survey was organised in Brussels Capital Region through the SaltaBru project, greatly increasing the number of records for this region. More recently, Saltabel became a study group of the Flemish NGO Natuurpunt and the working group revived with numerous activities and a growing number of recorders involved (http://www.saltabel.org). Since 2011, the online encoding platform http://www.waarnemingen.be is promoted and used for online reporting of records. Since 2012, the focus of the working group was put on enhancing the knowledge of threatened species in Flanders, with dedicated surveys prospecting historically known locations of e.g. Stenobothrus stigmaticus, Stenobothrus lineatus and Ephippiger ephippiger. The database described here, however, does not contain these recent records. The Netherlands are currently also working on a new atlas through waarneming.nl (http://www.waarneming.nl/sprinkhaanatlas_start.php).
