Vleermuiskasten.nl - Bats in bat boxes in The Netherlands and Belgium

Latest version published by Dutch Mammal Society on Feb 15, 2021 Dutch Mammal Society

Vleermuiskasten.nl (bat boxes.nl) hosts open data on bats in bat boxes provided by volunteers, professional bat ecologists and researchers. Additional metadata is available at vleermuiskasten.nl. Both presence and absence records are shown.

Occasionally birds are recorded in batboxes and when this occurs the scientific name of these birds are recorded. When the bat boxes are unoccupied, the individual count is recorded as zero. (In these cases GBIF records the scientific name as 'Incertae sedis' which has no meaning for this dataset)
