Enregistrements de données
Les données de cette ressource données d'échantillonnage ont été publiées sous forme dune Archive Darwin Core (Darwin Core Archive ou DwC-A), le format standard pour partager des données de biodiversité en tant quensemble dun ou plusieurs tableurs de données. Le tableur de données du cœur de standard (core) contient 330 enregistrements.
1 tableurs de données dextension existent également. Un enregistrement dextension fournit des informations supplémentaires sur un enregistrement du cœur de standard (core). Le nombre denregistrements dans chaque tableur de données dextension 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. Le tableau des versions liste les autres versions de chaque ressource rendues disponibles de façon publique et permet de tracer les modifications apportées à la ressource au fil du temps.

Données sur le projet
Meetnetten.be is a suite of monitoring networks through which the Flemish Government is collecting high-quality information on 65 priority plant and animal species. These are species on which Flanders has 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 détude / de recherche | Flanders, Belgium |
| Description du design | Each monitoring network consists of fixed sample locations in which target species are 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 déchantillonnage
For Serotine bat (Eptesicus serotinus), Brown long-eared bat (Plecotus auritus) and Grey long-eared bat (Plecotus austriacus), two emergence counts took place outside the selected maternity roosts each year: one before juveniles emerge (late May - early June) and one when both adults and juveniles emerge (late July - early August). Emergence counts were conducted from 15 minutes before sunset until 15 minutes after the last bat had exited the building (if no bats were observed, the count lasted until 1 hour after sunset). Emergence counts were supported with handheld ultrasonic detectors, and in some cases with thermal imaging cameras. For Geoffroy's bat (Myotis emarginatus), two complementary protocols were used. Firstly, attic counts inside the roosts: one count took place inside the selected maternity roosts each year, when both adults and juveniles were present (late July - early August). Roosts were visited during the day, and a picture was taken of the bat clusters. The number of bats were then counted on these pictures. Secondly, emergence counts, following the same method as used for the three species mentioned above, were also conducted at one location for a limited period.
| Etendue de létude | Within a maximum of 36 squares in a 5x5 km UTM grid, located throughout Flanders, bats are counted at maternity roosts during late spring or summer. |
|---|---|
| Contrôle qualité | Data are collected using predefined sampling protocols. |
Description des étapes de la méthode:
- Researchers from INBO and Natuurpunt Studie define and document the appropriate sampling protocols 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 protocols.
- Volunteers enter the collected data in https://meetnetten.be.
- A custom SQL view is created in the meetnetten.be database (exceptionally combining two protocolIDs due to their complementarity) to map the original data to Darwin Core as an event core and occurrence extension.
- The Darwin Core views are connected to the INBO IPT and documented with metadata.
- The dataset is published and registered with GBIF.
