Wildlife on the Scottish island of Orkney is experiencing a remarkable recovery following the eradication of over 6000 predatory stoats. The conservation efforts have led to a surge in numbers of the native Orkney Vole and red-listed birds like Hen Harriers and Lapwings. The conservation project, launched five years ago, focused on eliminating the invasive stoats, which were first observed on the island in 2010. Through the use of humane lethal traps, more than 6500 stoats have been removed from Orkney, making it the largest project of its kind globally.
Conservation scientists have been monitoring the wildlife on Orkney and have reported significant increases in successful nesting attempts of ground-nesting birds such as the Hen Harrier, as well as rare waders. Additionally, there has been a notable increase in the activity of Orkney Voles, with indications of a 200% rise in the species. The Orkney Native Wildlife Project, initiated in 2019, has stated that its mission to safeguard bird and small mammal populations on the islands is showing positive results.
The introduction of stoats in 2010 posed a serious threat to the native species of Orkney, as stoats are skilled predators that prey on small mammals, birds, and eggs. The stoats’ hunting behaviour, which includes caching excess prey for later consumption, had a devastating impact on the ecosystem. However, a team of international experts, in collaboration with local communities, RSPB Scotland, and the Scottish Government, have successfully culled thousands of stoats from the islands since 2019.
Anne McCall, director of RSPB Scotland, described the project as a testament to successful conservation efforts amidst a wider nature crisis affecting Scotland’s wildlife. The restoration of natural balance on Orkney has been a pivotal achievement, reversing the damage caused by the accidental introduction of stoats. The positive impact on ground-nesting birds and the Orkney Vole population is a promising sign of the project’s effectiveness.
NatureScot’s Head of Biodiversity, Dr Katherine Leys, commended the ongoing efforts to remove stoats from Orkney, which have led to promising signs of recovery for the island’s wildlife. Orkney, despite its small landmass, is home to a significant percentage of hen harriers, breeding seabirds, and red-listed species like curlews and lapwings, highlighting the importance of conservation initiatives in the region. The Orkney Vole, a unique subspecies exclusive to the island, further underscores the significance of preserving Orkney’s diverse ecosystem.
In conclusion, the successful eradication of stoats from Orkney represents a major milestone in wildlife conservation efforts, showcasing the positive outcomes of collaborative initiatives and dedicated conservation work. The resurgence of native species and the restoration of ecological balance on the island serve as a compelling example of the positive impact that targeted conservation projects can achieve in protecting biodiversity and safeguarding endangered wildlife populations.
