Control predators not on islands for seabirds
A before-and-after study at three sites in northern North Island, New Zealand (Wilson & Hansen), found that the population of New Zealand fairy terns Sterna nereis davisae increased from a low of five breeding pairs in 1987 and an annual decline of 1.5% to between 35 and 40 individuals in 2005 and an annual increase of 1.4%, following the continual trapping of introduced mammalian predators (feral cats Felis catus, hedgehogs Erinaceus europaeus, stoats Mustela erminia, ferrets M. putorius, weasels M. nivalis, Australian brush-tailed possums Trichosurus vulpecula and rats Rattus spp.) from 1992 onwards. On average 100 hedgehogs and 12 cats were trapped each year.
