Management actions
Implement targeted control of rats and cats in natural areas to reduce predation on the Norfolk Island robin. Restore native forest inside the national park, but also outside the park, with patches of appropriate size, composition, and physical connectedness, to enable passerine birds to expand their range. Conduct weed management (particularly red guava) with planting of native vegetation to avoid habitat becoming unsuitable and to allow ground feeding.

Recovery target
The recovery target is shown in Table 54.

EPBC Act status  Estimated population (2023)  Where known populations occur  2034 target
Vulnerable       750 (700–800)                59% in the national park       The population is at least 1500 individuals and the distribution extends outside the national park and its fringes to other areas of the island (such as other reserves and more southern parts of the island)
                                              1% in public reserves
                                              40% in other land
