BatMapper is a project based at Stockholm University to map bat activity across Sweden. We collected bat observations from the public during 2019 to 2021 and were particularly interested in information about bat roosts but any observations of bats were welcomed. Locating bat roosts can be a difficult, time consuming task and public knowledge of suspected or known bat colonies is extremely valuable for our research as it minimises the time spent finding suitable colonies to study. We used a combination of manual counting of bats, ultrasonic detection of bat calls and genetic analysis to assess how climate and landscape affect bat colonies across a climatic gradient from Skåne to Norrland.

Note: we are no longer taking observations of bats and instead encourage you to report bat observations or locations of suspected colonies to ArtPortalen.
