These islands are uninhabited by humans but are an internationally important breeding site‍‍‍ for‍‍‍ hundreds of thousands of seabirds.



‍‍‍However, a‍‍‍ population of invasive non-native black rats had become established on the Shiants following their accidental introduction several hundred years ago. Research found that the rats were feeding on seabird eggs and chicks and it is likely that rat presence was preventing other seabird species such as storm petrels from colonising the islands.

‍‍‍The Shiant Isles Seabird Recovery Proje‍‍‍ct

The project is a partnership between the Nicolson family, RSPB Scotland, and Scottish Natural Heritage (SNH). The four year project began in autumn 2014 with the aim of removing the black rat population to protect the existing seabird colonies and subsequently to encourage Manx shearwaters and storm petrels to colonise the islands. The ambitious rat removal operation was undertaken during the winter ‍‍‍‍‍‍of 2015-2016 and in the following years intensive monitoring was undertaken in order to detect any remaining rats and to assess the impact of rat removal on the seabirds and wider ecosystem of the Shiant Isles

Funding was provided by the European LIFE fund LIFE13/NAT/UK/000209 LIFE+ SHIANTS, SNH and RSPB.
