Home River Bioblitz

Wasserfledermaus klammert an Steinwand

The Home River Bioblitz is calling on people worldwide to experience their local rivers using the iNaturalist app from 23 to 25 September 2022 to support biodiversity research. Last year, 1,300 people on five continents participated.

Do you live near a river or water body and want to know what bat species live there? Or do you have the impression that many people don't know anything about the bat world? Biologist Julia Lorenz invites you to explore the biodiversity of bats at Fauler See on 23 September 23.

On this night hike we will dive into the world of bats and discover different bat species. After the sun has set, bats are particularly active, so we can watch them hunting and make their ultrasonic calls audible with a detector. Afterwards, we enter our observations into iNaturalist.

The excursion will be led by biologist Julia Lorenz and Moritz Müller, who both work as scientific coordinators at the museum's Citizen Science Competence Center.
