Working in Partnership for the Future of the Severn Estuary

The Severn Estuary is one of the largest estuaries in Britain and has the second highest tidal range in the world. It has a natural and cultural heritage which deserves special attention, and is a living and working environment for the communities who live around its shores and care about its future. The Severn Estuary Partnership (SEP) was set up in 1995 as an independent initiative, hosted by Cardiff University, to work with local stakeholders in promoting a sustainable approach to the planning, management, and development of the Severn Estuary for all who live and work here.
