Abstract

The efficacy of surveys in detecting Canada Lynx (Lynx canadensis) can vary considerably by geographic area. We conducted surveys using digital passive infrared trail video-cameras from January to April 2013, during the breeding season of the Canada Lynx, in the John Prince Research Forest in central British Columbia. We used snow-track surveys to test the efficacy of our camera surveys. We measured trail camera detection rates by survey week and location and we noted Canada Lynx activity and behaviours recorded by the cameras. The detection rate increased between January and April, reaching a peak of 8 Canada Lynx/100 camera-days in early April. Canada Lynx spent more time at camera sites displaying behaviours such as scent-marking and cheek-rubbing in late March. The combination of both snow-track and trail camera surveys was especially effective, with Canada Lynx detected at 77% of all monitored sites. Depending on survey objectives, it may be beneficial to conduct camera as well as other non-invasive survey methods for Canada Lynx during the breeding season, when survey efficacy and detection rates are maximized.
