Butterfly transect counts at the Zwin Nature Park

The data were collected since 2023, during spring and summer, in the ZNP’s provincial domain. This area is situated in a coastal dune zone between the ‘Zwin Plain’ and ‘Zwin dunes and polders’.

All these Zwin subareas are situated within the European Natura 2000 network. This dataset is published as a standardised Darwin Core Archive and includes for each sampling event a parentEventID, grouping eventIDs per season, the sampling protocol, with sample size and unit, the country code, longitude and latitude with geodetic datum and coordinate uncertainty (in the event core), and for each occurrence, an occurrenceID, the scientific name, Dutch vernacular name, taxon rank, occurrence status (absent or present), the number of recorded individuals, and the identifiedBy term for the field observer’s name (in the occurrence extension).
