Many species of animals and plants wich play an important role for nature conservation are highly elusive. The Eurasian otter (Lutra lutra) is one of these species. The Eurasian otter is very cryptic and, due to its mostly nocturnal activity, hard to observe. Since they use their scats for intraspecific communication, the most common non-invasive detection method is the search for its scat. Usually, specifically trained persons searched for and collected scats for further analyses. However, during the last study between 2006 and 2012 the sympatric occurrence of the American Mink (Neovison vison) increased dramatically. While during the first three years, most of the collected scats belonged to the Eurasian otter, 10% of the scats visually identified as Eurasian otter belonged to the Mink in 2010-2012. In total, 34% of the scats were found to be from sypatric carnivores. As the main diet of the carnivores in the study area consists of fish, their scats were almost identical in shape, color and smell. Thus, verifying the scat bevore using expensive genetic methods would be extremely helpful.
