About Bat Mapper

BatMapper is a project based at Stockholm University to map bat activity across Sweden. We want your observations of bats to help us with an ongoing research project. We are particularly interested in information about bat roosts but any observations of bats are welcome.  Locating bat roosts can be a difficult task and this is why we want you to tell us if you know or suspect that bats are roosting in your house, garden or near to where you live. This information is invaluable to us and will help us with our research on the effects of climate and landscape change on roosting bats.

This project is funded by the Bolin Center Research Area 7: Landscape and Climate.

What is our goal?

Ultimately, we want to understand how bat roosting behavior is responding to changing landscapes and climates. We plan to carry out monitoring of bat roosts in some of the localities recorded on BatMapper using a Citizen Science approach i.e. we would like your help to carry out that monitoring. Therefore, if you are interested in taking part in that side of the project let us know through the “report your sighting” page.


What happens to the data?

The information on bat activity and roosts will be used to guide our research project.  On the publicly available map bat records are only visible to approximately 1km resolution to protect the exact location. All data will also be shared with ArtPortalen.
