Every winter, the Scandinavian wolf population is surveyed using non-invasive genetic sampling (NGS) and snow-tracking to assess its annual status and trends. During 2017/18, search intensity and the proportion of samples genotyped was unusually high, resulting in more than 3 000 samples associated...
