Restoring South Georgia for its endemic and native species
The introduction and spread of and other rodents to South Georgia is devastating the island’s environment. Already whole areas have been decimated by rodents, which threaten to penetrate the few remaining rodent-free areas of South Georgia. SGHT's groundbreaking
The impact of rodents on South Georgia
The arrival of rats and other rodents on South Georgia as stowaways on sealing and whaling ships had a catastrophic effect on the island’s native bird populations. Rats eat the eggs and chicks of many ground-nesting bird species. As a result, the main island has been all but abandoned by the storm petrels, prions, diving petrels and blue petrels that once nested there.
The endemic once bred throughout the island. Now it is listed as near-threatened. Its breeding is confined to rodent-free offshore islands and islets, and the few remaining main-island areas that are protected from rodent invasion by sea-level glaciers.
As a result of global warming, South Georgia’s glaciers are retreating rapidly – two glacial barriers have been lost in the last few years alone. Without these barriers, the few remaining rodent-free areas will quickly be overrun and South Georgia’s remaining bird populations will suffer the consequences.
The SGHT Habitat Restoration Project aims to eradicate introduced rats and from South Georgia by 2015. Fundraising for Phase 2 (clearance of rodents from the entire north-west of the island, some 580km2) is complete.
Undertaking the Project has only been possible because of the generosity of SGHT’s donors and the support of those people who have offered their experience and expertise to help with its planning and implementation.
The future of the SGHT Habitat Restoration Project
While sufficient funding has been raised for Phase 1 and Phase 2 of the Project, we now urgently require funding for the final season of work in 2015, the eradication of rodents from the remainder of South Georgia. Another £3 million (US$5 million) will be needed to complete the work.
Ultimately, the whole of South Georgia will be overrun by rats and mice unless every single rodent is eradicated, and soon. Our objective is clear – we must remove every rodent from every piece of land on South Georgia, and leave it rodent-free for generations to come.
Your support for SGHT can directly help return millions of seabirds to South Georgia, and restore the island’s native ecology.
