2020-09-16 eng Meetnetten.be - Egg counts for butterflies 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 egg counts for 1 priority butterfly species (Phengaris alcon). Here it is published as a standardized Darwin Core Archive and includes for each sampling event an eventID, date, location and sampling protocol (in the event core) and for each occurrence an occurrenceID, the number of recorded individuals, status (present/absent) and scientific name (in the occurrence extension). Issues with the dataset can be reported at 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. We have released this dataset to the public domain under a Creative Commons Zero waiver.

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 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. Phengaris alcon (alcon blue / gentiaanblauwtje) can be found in wet heathlands with Gentiana pneumonanthe (marsh gentian / klokjesgentiaan) and a sufficient number of ants. Not the butterflies, but the eggs of this species are counted on the host plant. Either the entire area is examined and all eggs are mapped or sample areas are used (in the case of large populations). Sampling was done using the protocol described in Maes et al. (2019) and explained to volunteers in Ledegen et al. (2018). Egg counts for Alcon blue are done in plots of 10 x 10 m on locations with the highest density of gentians. Counting takes place once a year, in August. Data are collected using a predefined sampling protocol. Meetnetten.be Frederic Piesschaert 0000-0002-5843-646X pointOfContact 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. Flemish Government Flanders, Belgium 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.
