Description

Meetnetten.be - Transects for fire salamanders 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 site counts for 1 priority species (Salamandra salamandra), as well as other amphibians observed during sampling. 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.

We have released this dataset to the public domain under a Creative Commons Zero waiver. 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. If you have any questions regarding this dataset, don't hesitate to contact us via the contact information provided in the metadata or via opendata@inbo.be.

Sampling Description

Study Extent

Salamandra salamandra, the Fire salamander occurs mainly in old oak and beech forests, where the species reproduces in small brooks, pools and puddles.

Sampling

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).

Quality Control

Data are collected using a predefined sampling protocol.

Method steps

  1. Researchers from INBO and Natuurpunt Studie define and document the appropriate sampling protocol for the target species.
  2. Fieldwork is planned and coordinated by Natuurpunt Studie, using https://meetnetten.be.
  3. Data are collected in the field by specialized volunteers, using the predefined sampling protocol.
  4. Volunteers enter the collected data in https://meetnetten.be.
  5. A custom SQL view is created in the meetnetten.be database to map the original data to Darwin Core as an event core with an occurrence extension
  6. The Darwin Core views are connected to the INBO IPT and documented with metadata.
  7. The dataset is published and registered with GBIF.

Taxonomic Coverages

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.
