The Challenge
Rathlin’s seabirds are threatened by brown rats and ferrets.
Both are invasive non-native species on Rathlin, with rats introduced in the 19th century and ferrets released in the mid-1980s. They are now believed to have been the major drivers behind significant declines in many of the island’s seabirds, as well as a range of small mammals, invertebrates and plants. Rats and ferrets also affect the people living on Rathlin – they damage peoples’ homes and smallholdings, restrict their ability to keep poultry, and risk the transmission of disease.
LIFE Raft aims to eradicate rats and ferrets from the island and put steps in place to decrease the likelihood of their return. Many hundreds of islands around the world have been restored in this way. In March 2026 Rathlin Island was declared ferret free, the first feral ferret eradication. If successful it will also be one of the largest islands in the world to be cleared of rats without the use of helicopters and one of the most populous islands to be restored as well. All-in-all, this means LIFE Raft’s work is significant not just for Rathlin, but for people restoring islands around the world.
