Résumé :	Corncrakes once occurred throughout the UK. Stable populations now occur only in the far north and west of Scotland, primarily on islands with High Nature Value farming systems and supported by agri-environment schemes for Corncrakes. Additionally, there is a small re-introduced population in England.Over the last thirty years, there has been nearly a threefold increase in the Scottish population thanks to conservation and agri-environment initiatives. These initiatives focus on delivering safe habitat through the creation of cover and late mowing of silage fields. However, increases have been restricted to core areas with almost no range expansion.Conservation delivery occurs in collaboration with farmers and crofters as well as on nature reserves on the Orkneys, in Sutherland and on the Outer and Inner Hebrides. The RSPB owns and manages six nature reserves on four of the islands within the Inner Hebrides of Scotland. One of these reserves, on the island of Coll, has been the location for much of the early, applied research into the breeding ecology of Corncrakes. Research findings have guided our management of other nature reserves in the Hebrides and also inform agri-environment prescriptions. In most cases, our persistence in producing and maintaining good conditions for breeding Corncrakes has had island wide population benefits for this species. These reserves hold a significant proportion of the UK's Corncrake population and act as focal points for learning and demonstrating good practice.
