The Flow Country is a vast area of bog peatland in Caithness and Sutherland, northern Scotland. It is the largest blanket bog in Europe, and covers about 4,000 km2 (1,500 sq mi). It is an area of deep peat, dotted with bog pools, and is a very important habitat for wildlife. As peat is largely made up of the remains of plants, which are themselves made up of carbon, it locks up large stores of carbon for thousands of years. This carbon would otherwise be released to the atmosphere and contribute to global warming. In 2024 the Flow Country was awarded World Heritage status by UNESCO on account of its unparalleled blanket bog habitat. It includes the Forsinard Flows National Nature Reserve and the Caithness and Sutherland Peatlands.
