說明

Meetnetten.be - Site counts for butterflies 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 2 priority butterfly species, as well as other butterflies 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), the cloudiness, temperature, and wind force at the time of the event (in the measurement or fact extension) 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.

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.

計畫資料

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.

研究區域描述 Flanders, Belgium
研究設計描述 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.

取樣方法

Sampling was done using the protocol described in Maes et al. (2019) and explained to volunteers in Ledegen et al. (2018). A site count is similar to a transect in that is it visited multiple times, but unlike a transect it is not divided into different sections. A route is mapped out in such a way that observers pass potentially interesting locations and that it can be walked in about an hour. 1. Apature iris (purple emperor / grote weerschijnvlinder): observation locations are recorded and per route the maximum number of butterflies seen at the same time is noted. Also, for each count, the duration of the search is noted. Three censuses are performed between 10 June and 20 July. 2. Satyrium ilicis (ilex hairstreak / bruine eikenpage): counted along a fixed route, but not divided into sections: butterflies that fly further than 5 m are also counted. Each observed butterfly is recorded. The count takes place three times between the beginning of June and mid-July, at 13 counting areas.

研究範圍 For two butterfly species in Meetnetten.be (Apatura iris and Satyrium ilicis) the choice was made to count these by site rather than transect. This is because these species are mainly found in lower quantities and it would be too likely to be missed in a transect count. 1. Apature iris (purple emperor / grote weerschijnvlinder) is undoubtedly one of the most spectacular butterflies in Flanders. It is a forest species that lives in tree canopies and is not always easy to find. This summer butterfly is followed up at about ten locations each year. Because the butterflies often fly high, they are counted along a fixed route (but not per section or within an imaginary cage). 2. Satyrium ilicis (ilex hairstreak / bruine eikenpage) is in sharp decline in Flanders. Mapping this decline is not evident: in its habitat (forest edges and heathland with scattered small oaks) the species often hides well. We count this species by means of an area census instead of a classical transect census.
品質控管 Data are collected using a predefined sampling protocol.

方法步驟描述:

  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.
