Description
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.

Enregistrements de données
Les données de cette ressource données d'échantillonnage ont été publiées sous forme d'une Archive Darwin Core (Darwin Core Archive ou DwC-A), le format standard pour partager des données de biodiversité en tant qu'ensemble d'un ou plusieurs tableurs de données. Le tableur de données du cœur de standard (core) contient 21 enregistrements.
1 tableurs de données d'extension existent également. Un enregistrement d'extension fournit des informations supplémentaires sur un enregistrement du cœur de standard (core). Le nombre d'enregistrements dans chaque tableur de données d'extension est illustré ci-dessous.
Cet IPT archive les données et sert donc de dépôt de données. Les données et métadonnées de la ressource sont disponibles pour téléchargement dans la section téléchargements.

Données sur le projet
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.

| Description du domaine d'étude / de recherche | Flanders, Belgium |
| Description du design | 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. |

Méthodes d'échantillonnage
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.
| Etendue de l'étude | 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. |

Description des étapes de la méthode:
- 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.
