Hundreds of swallow nests were discovered with help of citizen scientists in Lower Austria in 2019. With further support of trainees from the AOC Seebarn, a possible basis for long-term monitoring of swallow nests in Lower Austria was created, providing first insights into public acceptance of house martins and barn swallows. The current results are to be seen as a snapshot of the year 2019. Continuation and expansion of the swallow nest monitoring based on citizen science aims to evaluate the sustainable impact of citizen science for a long-term conservation project.
