Meetnetten.be - ABV Common breeding birds in Flanders, Belgium (post 2016) 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 counts for bird species breeding in Flanders . Here it is published as a standardized Darwin Core Archive and includes for each sampling event an eventID, date, location, samplingEffort and sampling protocol (in the event core) and for each occurrence an occurrenceID, the number of recorded individuals, status (present/absent), life stage and scientific name (in the occurrence extension). Issues with the dataset can be reported at https://github.com/inbo/meetnetten-occurrences/issues
The breeding birds project is a joint initiative of the Institute for Nature and Forest Research (INBO) and the Vlaamse Vogelwerkgroep of Natuurpunt, in collaboration with Natuurpunt Study.
The data is collected to discover trends in long and short term breeding bird occurrences in Flanders and is used for the EU reporting on trends, distribution and future prospects of the species listed in the Annex 2 and 4 of the Habitats Directive.

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.
|研究設計描述||Each monitoring network consists of fixed sample locations in which the target species is 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.|
The atlas of breeding birds in Flanders (https://www.gbif.org/dataset/81c5a091-6e94-40db-a2a4-48f4de42d410) was based on territory mapping in 5×5 km UTM-squares with additional information collected in a subset of 8 1×1 km squares (Vermeersch et al., 2004). Information in over 5,000 1×1 UTM-squares was already available,so we chose that grid as a basis for the new census. The grid was then randomly stratified over 6 habitat types (farmland, woodland, urban, suburban, heathland and marshland) and finally, 6 points were randomly assigned to each grid cell. There are 1200 randomly selected UTM 1km squares that will be counted. Each point (6 points in every UTM 1km grids quare) has to be counted three times in a year in predefined periods (DD/MM): 01/03-15/04, 16/04-31/05 and 01/06-15/07. All six points in a square have to be counted on the same day and subsequent counts of the same points in different periods should lie apart for at least two weeks. Each point has to be counted for 5 minutes (This is a 90 minutes per square in a year effort). The voluntary network Starting from the existing network in the BBV-project (special breeding birds), approximately 40 regional coordinators were found throughout Flanders. The volunteer network is maintained by Natuurpunt.
|研究範圍||To describe the long-term abundance from a set of general breeding birds in Flanders, to describe the distribution of the selected species and the changes over time and to describe (relative) densities of a number of species. The first published dataset on the common breeding birds monitoring can be consulted here: https://doi.org/10.15468/sccg5a This dataset includes all the counts after July 2016.|
|品質控管||All records are validated|
- Researchers from INBO and Natuurpunt Studie define and document the appropriate sampling protocol for the target species.
- Fieldwork is planned and coordinated by Natuurpunt Studie, using https://meetnetten.be.
