The use of camera trapping is a useful way to monitor wild animals, especially the more elusive species that are more difficult to detect like the Eurasian lynx. In Sweden tracks left in the snow by the animals are used to monitory and evaluate regional abundance of Eurasian lynx. The warmer winters have made it harder in some areas, and camera trapping may be a good replacement for this method. In this study 165 camera positions from the middle of Sweden have been evaluated. The aim of the study was to look at several factors; roads, harvested forest, glacial moraine (ground type), buildings, past traces, scent stations and cadaver and find if there was a link between them and capturing lynx visits on photo/film, as this could provide better and more efficient methods in monitoring lynx. The coordinates of the different camera positions were entered into a GIS program. Based on different buffer zones around each camera position (50 to 500 meters in radius), the various factors have been distinguished, that is, if the factor existed or not in the camera area. Scent stations and carcasses were already fixed factors for certain camera positions. The results indicate that there is a correlation between lynx visits and scent stations (Chi2 6,606; P <0,05), with a higher likelihood of a lynx visit at camera station with scent than without a scent. The result shows the importance in using lures when the purpose is to capture lynx on photo or film, as this increases the chance that the lynx passes the camera and the picture is taken. Other factors did not appear to have a significant impact on getting a lynx appear on film. |
