Meetnetten.be - Transects for Eresus sandaliatus 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 transect data for Eresus sandaliatus, one priority spider species. Here it is published as a standardized Darwin Core Archive and includes for each sampling event an eventID, date, location, locationID and sampling protocol (in the event core) and for each occurrence an occurrenceID, the number of recorded spiderwebs, 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 5x5 km Universal Transverse ...
