Description
Meetnetten.be - Exuviae counts for dragonflies 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 exuviae (larval skin remained behind after ecdysis) counts for 1 priority dragonfly species (Gomphus flavipes). more

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), the length of the transect (in the measurement or fact extension) and for each occurrence an occurrenceID, the number of recorded individuals, status (present/absent), life stage, sex 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.

We would appreciate it if you follow the INBO norms for data use (https://www.inbo.be/en/norms-data-use) when using the data.

The target dragonfly species for Meetnetten.be are listed at https://meetnetten.be/#group-6. Other dragonflies observed during the sampling are momentarily not included. This dataset covers the larval skin protocol, for which there is 1 target species. In a later phase, when the monitoring of Gomphus vulgatissimus is operational, more data will be included.
Sampling was done using the protocol described in De Knijf et al. (2019) and explained to volunteers in Ledegen et al. (2017). 1. Gomphus flavipes (River Clubtail/ Rivierrombout): During a count of larval skins, the riparian bank is slowly crossed over a length of 500 m and every larval skin found is collected. The location is preferably read with a GPS. Each transect is visited once every 10 days and this in the period from 1 June to 15 August (6 visits in total).
