Meetnetten.be - Sightings for Stenobothrus stigmaticus in Flanders, Belgium is a sampling event dataset published by the Research Institute of Nature and Forest (INBO). It is part of the Meetnetten.be suite of monitoring networks for priority species in Flanders, in which data are collected at fixed locations using a standardized protocol (https://meetnetten.be). This dataset contains counts of the Lesser mottled Grasshopper Stenobothrus stigmaticus in Flanders. Here it is published as a standardized Darwin Core Archive and includes for each sampling event an event ID, date, location, sampling effort and sampling protocol (in the event core) and for each occurrence and occurrence ID, the number of recorded individuals, status (present/absent), life stage and scientific name (in the occurrence extension). Issues with the dataset can be reported at https://github.com/inbo/meetnetten-occurrences/issues
Generalized and/or withheld information: as these are sensitive priority species, location information is generalized to 1, 5 or 10 km Universal Transverse Mercator (UTM) grid cells. Original locations are available upon request.

The data in this sampling event 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 21 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
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.
The table below shows only published versions of the resource that are publicly accessible.

Meetnetten.be is a suite of monitoring networks through which the Flemish Government is collecting high-quality information on priority plant and animal species. These are species on which Flanders have to report to Europe in the framework of the Habitats and Birds Directives, but also other species that are important for the Flemish nature policy.
|Study Area Description||Flanders, Belgium|
|Design Description||Each monitoring network consists of fixed sample locations in which the target species is counted based on a standardized protocol. Data collection relies mainly on specialized volunteers, coordinated by the NGO Natuurpunt Studie. Fieldwork is planned and monitored with the web tool https://meetnetten.be, which is also used for entering the collected data.|
The personnel involved in the project:
Sampling was done using the protocol described in De Knijf et al. (2016). We monitor Stenobothrus stigmaticus using a capture all method. Annually, four plots of 10 m x 10 m are sampled in the period July to mid-September. Within these plots each grasshopper is captured, named and time of capture was noted.. This was performed until no more grasshoppers were caught within the plot of 10 m x 10 m for about ten minutes. At the end of the count, all grasshoppers are released at the site.
|Study Extent||The question we are trying to answer with the grasshopper monitoring network is whether the species in Flanders over a 24-year period is decreasing by at least 25% or increasing by 33% (Westra et al.2014). Since the 2 species (Stenobothrus stigmaticus and Ephippiger ephippiger) of monitored grasshoppers occur at less than 30 sites, all sites are monitored completely. Schavertje - Stenobothrus stigmaticus - The Lesser mottled Grasshopper is a species of grasshopper which can only be found in three places in West Flanders. This critically endangered species is in Flanders found on barren grasslands on dunes and sands characterised by domination of mosses and lichens.|
|Quality Control||All data is validated|
Method step description:
- Researchers from INBO and Natuurpunt Studie define and document the appropriate sampling protocol for the target species.
- Fieldwork is planned and coordinated by Natuurpunt Studie, using https://meetnetten.be.
- Data are collected in the field by specialized volunteers, using the predefined sampling protocol.
- Volunteers enter the collected data in https://meetnetten.be.
- A custom SQL view is created in the meetnetten.be database to map the original data to Darwin Core as an event core, occurrence extension and measurement or fact extension.
- The Darwin Core views are connected to the INBO IPT and documented with metadata.
- The dataset is published and registered with GBIF.
