Description

Meetnetten.be - Sightings for Eresus sandaliatus 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 area count data for Eresus sandaliatus, one priority spider species. 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 spider webs, 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 5x5 km Universal Transverse Mercator (UTM) grid cells. Original locations are available upon request.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 8 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

  • Event (core)
    8
  • Occurrence 
    8

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data

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.

Title Meetnetten.be
Identifier meetnetten.be
Funding Flemish Government
Study Area Description Flanders, Belgium
Design Description 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.

Sampling Methods

Sampling was done using the protocol described in Van Keer et al. (2020). 1. The Ladybird Spider will be monitored using transects or area counts within delimited areas, where each visible part of the web will be counted. This dataset deals with area count data.

Study Extent To support the Flemish and European nature policy, reliable information is needed on the distribution and trends of Flemish and European priority species. 1. Eresus sandaliatus (Martini & Goeze, 1778). The Ladybird spider builds a dome-shaped web on the ground, which turns into a vertical underground living tube on one side. The spider usually lives in this 5-10 cm deep tube. It often catches large and powerful prey, such as dung beetles and ground beetles.
Quality Control Data are collected using a predefined sampling protocol.

Method step description:

  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, occurrence extension and measurement or fact 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.
