Brushtail Possums (Trichosurus vulpecula Kerr) in a New Zealand Beech (Nothofagus) Forest
Brushtail possums were studied over a period of four years by live-trapping, poisoning and kill- trapping on an altitudinal transect (455-1500 m a.s.l.) in beech (Nothofagus) forest in South Island, New Zealand. There was a single breeding season in autumn in which most females (including 80% of one-year- olds) panicipated. Trap-revealed ranges of adults were up to 1 km long and some immature males dispersed up to 10 km. Capture rates in live-traps were highest in beech/podocarp forest at 455-460 m a.s.l. and declined with altitude.
