A UNESCO Biosphere Reserve uniting chalk downland, coast, and city along England's southeast shore.
Brighton and Lewes Downs Biosphere Reserve
The Brighton and Lewes Downs Biosphere Reserve, now promoted under the name The Living Coast, is a UNESCO-designated Biosphere Reserve on the southeast coast of England in the county of Sussex. Designated in 2014, the reserve lies within and alongside a central section of the South Downs National Park and is anchored on the Brighton chalk block, the stretch of chalk hills bounded by the River Adur to the west and the River Ouse to the east.
Its landscape combines sweeping chalk downland with dramatic chalk cliffs, shingle beaches, river estuaries, and a stretch of inshore English Channel waters. The reserve sits at the interface between rural Sussex countryside, an iconic coastline, and the dense urban environment of Brighton and Hove, making it one of the most thoroughly human-influenced biosphere reserves in the United Kingdom.
The reserve is notable for combining high-value terrestrial habitats, particularly species-rich lowland chalk grassland, with marine ecosystems that include unusually well-developed subtidal chalk reef. It brings together protected areas, working farmland, a major maritime fishery, and one of England's most visited coastal cities within a single internationally recognized framework for conservation and sustainable development.
