Management actions
Control the main predators, black rats and feral cats, with targeted control of rodents in natural areas to protect Norfolk Island golden whistler nests (predation by rats has a strong influence on fledging rates). 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.

Recovery target
The recovery target is shown in Table 52.
Table 52 Recovery target for Pachycephala pectoralis xanthroprocta
EPBC Act status  Estimated population (2023)  Where known populations occur  2034 target
Vulnerable       1,671                        42% in the national park       The population is at least 2000 individuals and distributed across Norfolk Island
                 (1,372–1,970)                1% in public reserves
                                              57% in other lands
