Butterfly monitoring scheme in Flanders, Belgium

Butterfly monitoring scheme in Flanders, Belgium is a sampling event dataset published by the Research Institute of Nature and Forest (INBO). This dataset contains transect data for butterfly species, collected using a standardized protocol since 1991. Data from 1991-2014 were collected in the INBO Vlinderdatabank (Maes et al. 2016), but have since been migrated to the meetnetten.be database, where new observations are recorded. Here, the dataset 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 in a transect, lifestage, status (present/absent), vernacular and scientific name (in the occurrence extension).
