A before-and-after study on Cabbage Tree Island, southeast Australia (Priddel & Carlile 2007) found that the population of Gould’s petrel Pterodroma leucoptera leucoptera has increased since the eradication of European rabbits Oryctolagus cuniculus in the austral winter of 1997, with more breeding pairs (186-599 pairs in 1989-97, before rabbit eradication vs. 818–1025 pairs in 1997-2006, after eradication), higher breeding success (17–59% success, average of 33% vs. 46–57%, average of 51%) and more fledglings produced (31-331 fledglings/year vs. 374-488 fledglings/year). Rabbit removal (by sequential epidemics of myxomatosis, rabbit haemorrhagic disease and brodifacoum application) was, however, only one of several conservation interventions and the conservation of Gould’s petrels is also discussed in ‘Provide artificial nesting sites’, ‘Provide supplementary food’, ‘Translocate individuals’, ‘Artificially incubate and hand-rear birds in captivity’, ‘Remove problematic vegetation’ and ‘Control avian predators on islands’.
