Invasive non-native species are having severe ecological impacts across the world, and we now know that eradicating invasive mammals from just 169 islands would improve survival prospects of almost 10% of the world’s Critically Endangered and Endangered island vertebrate species.
Previously considered a relatively benign introduction to islands, house mice are now recognised as capable of driving some of the world’s largest and most iconic birds towards extinction. On three islands, in three different oceans, house mice have learnt to predate on seabirds more than 200 times their weight. This talk will concentrate on an exciting project underway to remove house mice from Gough Island, Tristan da Cunha, the UK’s most remote Overseas territory in the South Atlantic.
Gough Island is a globally important breeding site for multiple threatened bird species and is one of the only islands in the world where house mice have been recorded predating large seabird species, including scalping chicks and injuring adult albatrosses – and in some cases, pushing species rapidly towards extinction. Current estimates suggest that at least 2 million seabird chicks and eggs are being lost to the mice every year. The stakes are high in eradication operations and having mice as the invasive species requiring removal only adds to their complexity.
