Reintroductions are increasingly being used to restore species and ecosystems. However, chances of successful establishment are often low. Key to improving success is careful consideration of threats, threat mitigation, monitoring, and subsequent improvement to management. We demonstrate this planning, implementation, and review process using the reintroduction of an endangered mesopredator, the eastern quoll Dasyurus viverrinus, in the first attempt to reestablish it in the wild on mainland Australia. In March 2018, 20 captive‐bred quolls (10 male, 10 female) were released into Booderee National Park and monitored via telemetry, camera, and cage trapping. There were many unknowns and, despite thorough consideration of threats, there were surprising outcomes. Within 3 months, 80% of animals had died; half due to predation, an expected threat. Other threats were unexpected yet, due to good monitoring and responsive management, were quickly detected and effective mitigation implemented. These learnings have been incorporated into revised translocation procedures. One year later, four founder quolls remained and had successfully bred. We highlight lessons applicable to other reintroductions. These are, the importance of: (1) conducting a thorough review of threats and implementing appropriate mitigation; (2) targeted monitoring and responsive management; (3) effective communication, education, and engagement with the local community and stakeholders; and (4) ensuring learnings are disseminated and incorporated into future translocation plans. Threat assessment is an important step in identifying potential reasons for failure. However, actual threats can be realized only via experimentation and monitoring. Applying this knowledge to future reintroduction attempts can increase their chance of success. [ABSTRACT FROM AUTHOR]

The article discusses the current distribution of Abbott's Booby on Christmas Island based on occupancy data gathering during an island-wide survey in 2009. The study failed to find any evidence of a significant link between occupancy by Abbott's Booby and distance to the nearest road or to high-density Yellow Crazy Ant colonies. However, the research found that occupancy by Abbott's Booby was significantly and positively associated with both elevation and distance to the nearest disturbed area. Abbott's Booby nesting habitat is reportedly confined to the central plateau on Christmas Island and has shrunk because of major disturbances.
