Two different methods, hair traps and camera traps, were used to find out more about the occurrence and distribution of carnivores in the Donau Auen national park, located in the eastern part of Austria. Camera traps resulted in higher quality data on carnivore occurrence and distribution than hair traps. Hair traps failed to yield valid data due to weather conditions (flood event), floodplain conditions (snails) and the general construction plan (enclosure) of the hair trap. These methods resulted in detection of only the common carnivores such as red foxes, badgers, pine martens, stone martens and polecats. Neozoa, such as raccoons or enoks, were not detected. Similarly, native carnivore species such as weasels and stoats were not detected although they are likely to be present considering their generally wide distribution in Austria. It is assumed that they occur in such small populations, that the study period was too short to confirm their occurrence. Due to the resulting small sample size, correlations between habitat parameters and carnivore occurrence were not significant. However, this study shows that camera traps seem to be a good monitoring tool for carnivores as well as herbivores. Longer survey periods would bring more data and it will become easier to find significant correlations with habitat characteristics.
