Fabian Holzinger and Franziska Thurner describe how their interest in the local beavers began and what kind of work they do at the Beaverlab. They connect art with science and education. Beavers are a so-called keystone species and they shaped the landscapes and ecosystems for 15 million years, 14.99 million years later, humans brought them to near extinction. Especially in Austria, people, i.e. farmers are a bit hostile against these animals and are concerned about them “destroying” farmland. But they are back in Austria and Linz.
