The Arigna Mountains Special Area of Conservation (SAC) is located in County Leitrim, Ireland, encompassing a diverse upland landscape characterized by rugged mountains, blanket bogs, heathlands, and upland grasslands. This conservation site is particularly important for its habitat diversity, supporting internationally significant species such as the hen harrier, a rare bird of prey, and the slender naiad, a protected aquatic plant.
