AbstractThe factors that affect the trappability of the red fox (Vulpes vulpes L.) in alpine and subalpine New South Wales were examined by means of treadle snares. Trapping (1) on animal tracks without the use of a bait or lure, and (2) by setting snares around a bait, led to the capture of individuals of both sexes and all age-classes. A greater number of foxes was captured per number of snares set in winter than in other seasons because of the commensal foraging patterns of foxes at this time. Foxes were more likely to be caught within 100 m of their home-range boundaries during snow-free months and outside their home ranges while foraging at ski resorts in winter. Snares were found to be difficult to set, and foxes were captured in only 50% of sprung snares. Treadle snares caused no apparent long-term injuries to 40 red foxes that were radio- tracked and observed for 1–24 months after capture.
