The biggest threat to this species is poor breeding success following loss of eggs and chicks to rats, cats, coatis, and dogs, as well as to local people. Goats and rabbits are responsible for over-grazing that leads to soil erosion and the loss of suitable nesting burrows. Like many seabirds, this species is also threatened by the fishing industry, as it becomes entangled in fishing gear across its range. Pollution may also be a threat (2).
In 1935 the Juan Fernández Islands were designated as a National Park, but were only protected from 1967. In 1977 they were upgraded to become a Biosphere Reserve, and they have now been nominated for inclusion in the list of World Heritage Sites. The breeding site on Isla Mocha is in a guarded national reserve which has had a management plan since 1998. The government of Chile has worked to improve the habitat of the shearwater since 1997. Collecting chicks is illegal, but enforcement is weak, and further efforts are necessary. The removal of introduced mammals has been proposed (2).
