IMIS

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, behaviour, sex, status, (present/absent) 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.

The target species for Meetnetten.be are listed at https://meetnetten.be/#group-1. Other salamanders observed during the sampling are also included. This dataset covers the fire salamander protocol, for which there is 1 target species.
Fire salamanders have to be counted along fixed transects of ca. 1 km. Transect counts are walked between August 15th and November 15th on nights with high humidity, and preferably at temperatures higher than 5°C. Animals are searched for by means of a flashlight (6 m to the left and right of the trail). Each transect must be visited at least twice a year. Sampling was done using the protocol described in De Bruyn et al. (2015), updated by Speybroeck et al. (2020), and explained to volunteers in Lewylle et al. (2017).
