プロジェクトデータ

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.

収集方法

For Serotine bat (Eptesicus serotinus), Brown long-eared bat (Plecotus auritus) and Grey long-eared bat (Plecotus austriacus), two emergence counts took place outside the selected maternity roosts each year: one before juveniles emerge (late May - early June) and one when both adults and juveniles emerge (late July - early August). Emergence counts were conducted from 15 minutes before sunset until 15 minutes after the last bat had exited the building (if no bats were observed, the count lasted until 1 hour after sunset). Emergence counts were supported with handheld ultrasonic detectors, and in some cases with thermal imaging cameras. For Geoffroy's bat (Myotis emarginatus), two complementary protocols were used. Firstly, attic counts inside the roosts: one count took place inside the selected maternity roosts each year, when both adults and juveniles were present (late July - early August). Roosts were visited during the day, and a picture was taken of the bat clusters. The number of bats were then counted on these pictures. Secondly, emergence counts, following the same method as used for the three species mentioned above, were also conducted at one location for a limited period.

Method step description:

1. Researchers from INBO and Natuurpunt Studie define and document the appropriate sampling protocols 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 protocols.
4. Volunteers enter the collected data in https://meetnetten.be.
5. A custom SQL view is created in the meetnetten.be database (exceptionally combining two protocolIDs due to their complementarity) to map the original data to Darwin Core as an event core and 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.
