Red-tailed phascogales (Phascogale calura), a small, arboreal, nocturnal carnivorous marsupial, have been the subject of eight reintroduction attempts in the past seventeen years. Three of these reintroduction attempts have released juvenile animals without radio-collaring, and success is uncertain. In November 2022 twenty captive-bred juvenile phascogales were released into a feral-predator-free reserve: Mallee Refuge in South Australia. Our study was the first radio-tracking study of juvenile red-tailed phascogales and we uncovered important considerations for future releases. We radio-tracked nineteen individuals and placed remote cameras at nest boxes. We found that the juvenile phascogales were losing weight, and that males were prone to hyperdispersal. Our experience demonstrates that reintroductions to safehavens and lack of predation pressure are no guarantee of success. We posit that weight loss was caused by colder-than-average temperatures at the time of release with individuals entering torpor instead of actively foraging. Male phascogales are known to disperse widely; it is difficult to mitigate this behaviour. In response to weight loss we implemented a supplementary feeding regime. Dispersing males were tracked, trapped, and returned to the release site to retain them in the new population. With lessons learned, we will release eleven captive-bred adult phascogales in May 2023, implementing intensive monitoring and supplementary feeding immediately post-release. We will release mothers carrying pouch young in July 2023 in a soft-release scenario. We will present results of the juvenile release, as well as from our two planned adult releases, with a focus on using intensive monitoring to determine individual fate and success.
