Abstract:

The high adaptability enables the roe deer (Capreolus capreolus) to populate different regions and habitats. The space usage is governed by time use patterns, which fluctuate on a daily and yearly basis and have the effects on age- sex classes differ. The aim of this project is to attain more knowledge about the ecology of deer. This was undertaken by analysing photographs of deer taken by camera traps in the course of one year. Under the Wild Animal and human project, a systematic camera trapping was undertaken since 2012 in the study area Sihlwald on 19 case sites. The subsequent statistical analysis allows statements about the spatial use and activity of deer in the study area.
Overall, the data shows that deer have the largest share (43%) of observed species in this study area. Most events were registered at border areas. The gender distribution showed more females (47%) than males (30%) and in 23% of events sex determination was not possible. Where age determination was possible, the age class distribution shows that 37% were adults, 13% juveniles and 9% yearlings. However in 44% of events age determination was not possible. The highest diurnal activity of deer was recorded during twilight times, particularly during dusk. Deer appear to be least active during the night. Annually, the highest activity was obtained in spring and summer months and only very few events were recorded in autumn. The influence of climatic factors was inconclusive. Nevertheless, a weak trend towards increased activity at lower temperatures, decreased precipitation as well as periods of shorter sunlight periods could be detected.
Despite some challenges with the correct identification of deer using camera trap photographs, the results obtained show that camera trapping for ecological studies of deer is suitable. A continuation of monitoring, as well as the inclusion of data from complementary methods of investigation will be able to provide further insight and lead to a better understanding of the species.
