Understanding the space use and habitat needs of animals is essential for effective species conservation. Small animals use small structures that are difficult to monitor. LIB researchers have now used drones in a study to depict these small structures in high-resolution habitat maps. The research team was able to show how important low blackberry bushes are for sand lizards in the Dellbrücker Heide in Cologne. The drone method can find application in nature conservation and landscape planning.
