Twice every day, as the tide ebbs, the muddy waters of the Severn Estuary drain away to reveal around 100 sq km of intertidal land, a complex mosaic of saltmarshes, mud flats, sand banks, and rocky foreshore.
These habitats are home to a wide range of plants and animals, some of which are found nowhere else. Many are specially adapted to live in the harsh intertidal zone, with its widely fluctuating temperatures and salinity. Together they create an ecosystem as rich and varied as any tropical rainforest.
Join ecologist Ed Drewitt for an exploration of the land beyond the seawall.
