North Uist Machair and Islands SPA is located in the Outer Hebrides off the north-west coast of Scotland. It is a coastal site encompassing areas of rocky shore, sandy beaches and dunes, cultivated machair, saltmarsh, calcareous coastal plains and acid grassland. There are also important freshwater wetlands including eutrophic machair lochs, marshes and fens, and wet machair. These areas are important for both large numbers and high densities of breeding waders as well as Corncrake Crex crex. The Tigharry section is included specifically for Corncrake. In migration periods and during winter, the site holds important numbers of waders on the rocky and sandy shorelines, together with wintering Greenland Barnacle Goose Branta leucopsis.
