Welcome to the St Kilda Soay Sheep Project.

The Soay Sheep Project has been running in its current form since 1985, with continuous collection of information about individuals including genetic parentage, morphological data and life-histories. This has enabled ground-breaking research into topics including population dynamics, evolution and genetics, ageing and parasite infection in a natural setting.

Please use the links in the navigation bar to explore the site and find out about our research.
