The effect of attractant lures in camera trapping: a case study of population estimates for the Iberian lynx ( Lynx pardinus )

摘要: Capture–recapture analysis of camera trap data is a conventional method to estimate the abundance free-ranging wild felids. Due notorious low detection rates felids, it important increase probability during sampling. In this study, we report effectiveness attractants as tool for improving efficiency sampling in estimation Iberian lynx. We developed grid system stations which with and without attractant lures were spatially alternated across known lynx habitat. Of ten individuals identified, five detected at no (blind sets), nine, lured stations. Thirty-eight percent blind set station’s independent captures 10 % resulted photographs unsuitable correct individual identification. The total capture was higher than that obtained estimates cameras underestimated number lynxes compared cameras. our appears use increased trail and, therefore, accuracy capture–recapture analysis. observed failure detect may violate assumptions bias estimates.
