Movements, Activity Patterns and Habitat Use of Feral Pigs (Sus scrofa) in a Tropical Habitat

Abstract

Movements, activity patterns and habitat use of feral pigs were studied in a tropical woodland habitat by radio-telemetry, live-trapping and hunter returns. The mean aggregate home-range size was 33.5 km² for boars and 24.1 km² for sows. Feral pigs were rather sedentary, with no tendency to disperse great distances from their initial home ranges. Pigs were most active at night, with peaks of activity in the late afternoon and early morning. Pigs preferentially used the riparian vegetation strip bordering major rivers, and grain crops, when available. The implications for the management of pigs are discussed.
