The North Uist Machair and Islands is a protected wetland area in the Outer Hebrides of Scotland. A total of 4,705 hectares comprises seven separate areas: four sites on the west and north coasts of North Uist, as well as the whole of the island of Boreray and parts of Berneray and Pabbay in the Sound of Harris. The site primarily contains machair areas, with a range of habitats including sand dunes, acid grassland and freshwater wetlands, including nutrient-rich marshes and fens, wet and dry machair and saltmarsh. It has been protected as a Ramsar Site since 1999.^[1]
