Meetnetten.be - Chorus counts for Amphibia in Flanders, Belgium

Última versión Publicado por Research Institute for Nature and Forest (INBO) en Apr 15, 2021 Research Institute for Nature and Forest (INBO)

Meetnetten.be - Chorus counts for Amphibia 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 3 priority species (Hyla arborea, Epidalea calamita and Pelobates fuscus), as well as other amphibian species 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, 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.

Datos del Proyecto

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.

Título Meetnetten.be
Identificador meetnetten.be
Fuentes de Financiación Flemish Government
Descripción del Área de Estudio Flanders, Belgium
Descripción del Diseño 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.

Métodos de Muestreo

For the tree frog and spadefoot toad the number of calling males is counted in the reproductive habitat at least twice a year. 1. Male Pelobates fuscus call from the bottom of the waterbody. The calls being fairly weak, counting the exact number of calling males by ear can be challenging. This is particularly the case when other anurans such as Hyla arborea are calling simultaneously. Therefore, the use of an underwater hearing device or hydrophone is advocated. Each waterbody is investigated with waders, in order to approach the calling animals upto hearing distance. 2. Hyla arborea: Monitoring in the framework of the Tree Frog Monitoring Network is done by counting the number of calling males, or in some cases, by estimating the number. 3. For the Natterjack toad monitoring network, calling choruses need to be monitored three times. The number of calling males is counted or in some cases, when the population turns out to be too large, estimated. The number of calling males is counted exactly at each visit. For up to 50 animals the sounds are still good to distinguish and localize so that this is easy (Bauwens & Speybroeck, 2014; Groenveld et al., 2011). With more animals a more rough estimate can be given. 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).

Área de Estudio 1. Pelobates fuscus, or the common spadefoot toad, is found in fishless cattle drinking pools and relatively nutrient-rich ponds, but also in cut brook and river meanders in a fairly open, sandy environment. These are often water features in (buffered) heathlands, but also near dikes and even vegetable gardens and extensively managed fields. This type of habitat is rare in Flanders. The common spadefoot currently only occurs in the central part of Limburg. 2. Hyla arborea, or the common tree frog, is found in the scrubland of the Limburgse Kempen, a restricted section of the Antwerpse Kempen near the Belgian-Dutch border, and the dunes of the Zwin. In recent years, the Flemish population has increased. 3. Epidalea calamita or the Natterjack toad is a true pioneer species that thrives in dynamic environments. The species reproduces from April to August, when the animals gather in breeding pools and the males call loudly.
Control de Calidad Data are collected using a predefined sampling protocol.

Descripción de la metodología paso a paso:

  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.
