MOVEMENTS OF FERAL PIGS (SUS-SCROFA) AT SUNNY-CORNER, NEW-SOUTH-WALES

This study describes the movements of feral pigs at Sunny Corner in eastern New South Wales. Population density at this site was 2 pigs km-2. Twenty-two pigs (12 males and 10 females) were captured and fitted with telemetry transmitters. Aggregate home range for males (10.7 +/- 6.9 km2) was significantly greater than for females (4.9 +/- 1.4 km2) as was 24 h home range (1.4 +/- 1.1 km2, males and 0.8 +/- 0.4 km2, females). Seasonal home ranges were greatest in the winter and smallest in the autumn. These differences were attributed to variations in food availability. During all seasons there was a preference for creeklines that had vegetative cover. This was the result of thermoregulatory needs, refuge availability and food supply. Peak activity throughout the study occurred between 1900 and 2400 hours with little movement during the middle of the day. The implications of these results to management programs are discussed.
