Abstract Ecology often faces the problem that many threatened species are highly elusive but also conflict-laden.
Thus, proper monitoring data are inevitable for their conservation and management. Indirect monitoring
through scats is frequently used for such species, but scats of related species or species with similar diet are
often visually indistinguishable. Since genetic methods for species identification are time-consuming and
cost-intensive, a verification of the target species beforehand would be extremely beneficial in reducing effort
to the analysis of the target species only. Such species discrimination could be provided through speciesspecific scat detection dogs. Therefore, we evaluated the reliability of species-specific scat detection dogs for two mustelid species feeding on identical diets: the Eurasian otter (Lutra lutra) and the American mink (Neovison vison), both of which are conflict-laden and increasing their populations and distribution ranges in central Europe. Their scats resemble each other in morphology and odour, exacerbating the differentiation even for experts. To evaluate whether detection dogs can reliably discriminate between related species feeding on similar diets and if their use would be beneficial, we tested their abilities against those of humans.
