  1. Release translocated/captive-bred mammals in areas with invasive/problematic species eradication/control

    A study in 2001–2008 in a forest reserve in Queensland, Australia (Kingsley et al. 2012) found that following the release of captive-bred bridled nailtail wallabies Onychogalea fraenata and subsequent predator controls, numbers increased over a three-year period, but remained low compared to the total number released. Three years after the last release event, the estimated bridled nailtail wallaby population (31 individuals) was higher than at the time of the last release (15 individuals) but was lower than the total number that had been released (166 individuals). In 2001–2005, groups of 1–20 captive-bred wallabies were released on 14 occasions into a 565-ha private forest reserve. Ninety-seven wallabies were kept in two 50 × 50-m predator-proof holding pens for one week before release. Sixty-nine wallabies infested with parasites were treated before release. Predator control was carried out in 2004–2008. Wallabies were trapped in a 2-km2 area with 5–45 wire cage traps during 7–22 nights on eight occasions in 2005–2008.
