The bank vole Myodes glareolus was by far (87%) the most common species trapped, but also other species were observed (including shrews). We provide digital data collection forms and highlight the importance of long-term data collection.R, Version 4.2.2Birkebeinervegen, Innlandet, NorgeBirkebeiner road, Innlandet county, Norway10.46513111.02375761.46085661.247073The Research Council of Norway221056
