All going to plan, today marks one year until the Agulhas II leaves Cape Town for Gough Island on 15th May 2019 to start the mice eradication operation to protect endangered land and sea birds.

Gough Island, in the middle of the South Atlantic, needs our urgent help. Every year over one million seabird chicks are killed, pushing some species towards extinction. The chicks are killed by an invasive non-native species of house mouse that was introduced to Gough by humans.

The RSPB and Tristan da Cunha Government have developed an ambitious programme of conservation action. In 2019 rodenticide bait will be spread across Gough Island, eradicating the mice and restoring Gough to its natural state. This action will prevent the deaths of defenceless chicks year after year, halting decline and allowing populations to bounce back.


Programme objectives

  • To prevent the extinction of the Critically Endangered Tristan albatross and Gough bunting
  • To restore Gough Island to its natural state, ensuring the island remains one of the world's most important seabird nesting sites, worthy of World Heritage Site status
  • To support Tristan da Cunha Island Council as custodians of Gough Island and ensure a lasting legacy for Tristan da Cunha, a British Overseas Territory.




Eradication operation

The solution is relatively straightforward, though the operation is logistically complex, mainly because of the island's remoteness, tough terrain, and harsh weather conditions. Using helicopters, highly experienced pilots will spread cereal bait pellets containing a small amount of proven rodenticide across the island. In difficult to reach areas bait will be spread by hand to ensure that every mouse encounters rodenticide pellets.

We are well-placed to carry out such an important and complex operation. The RSPB and our partners have years of island eradication experience to draw on.

The programme also involves some of the world’s leading experts in the field of rodent eradications who have been buoyed by the success of the Macquarie Island Pest Eradication Project and the successful delivery of the South Georgia Habitat Restoration Project. Both of these projects highlight that complex island restoration projects are achievable in difficult environments.

The operation is on track to go ahead in the Southern winter of 2019 (May-August).
