Factors affecting the trappability of red foxes in Kosciusko National Park

Abstract

The 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.
