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 39 enregistrements.
2 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.

Couverture taxonomique
The target butterfly species for Meetnetten.be are listed at https://meetnetten.be/#group-4. Other butterflies observed during the sampling are also included. This dataset covers the site count protocol, for which the target species are Apature iris (purple emperor / grote weerschijnvlinder) and Satyrium ilicis (ilex hairstreak / bruine eikenpage).

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 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
Sampling was done using the protocol described in Maes et al. (2019) and explained to volunteers in Ledegen et al. (2018). A site count is similar to a transect in that is it visited multiple times, but unlike a transect it is not divided into different sections. A route is mapped out in such a way that observers pass potentially interesting locations and that it can be walked in about an hour. 1. Apature iris (purple emperor / grote weerschijnvlinder): observation locations are recorded and per route the maximum number of butterflies seen at the same time is noted. Also, for each count, the duration of the search is noted. Three censuses are performed between 10 June and 20 July. 2. Satyrium ilicis (ilex hairstreak / bruine eikenpage): counted along a fixed route, but not divided into sections: butterflies that fly further than 5 m are also counted. Each observed butterfly is recorded. The count takes place three times between the beginning of June and mid-July, at 13 counting areas.
| Etendue de létude | For two butterfly species in Meetnetten.be (Apatura iris and Satyrium ilicis) the choice was made to count these by site rather than transect. This is because these species are mainly found in lower quantities and it would be too likely to be missed in a transect count. 1. Apature iris (purple emperor / grote weerschijnvlinder) is undoubtedly one of the most spectacular butterflies in Flanders. It is a forest species that lives in tree canopies and is not always easy to find. This summer butterfly is followed up at about ten locations each year. Because the butterflies often fly high, they are counted along a fixed route (but not per section or within an imaginary cage). 2. Satyrium ilicis (ilex hairstreak / bruine eikenpage) is in sharp decline in Flanders. Mapping this decline is not evident: in its habitat (forest edges and heathland with scattered small oaks) the species often hides well. We count this species by means of an area census instead of a classical transect census. |

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.
