Project summary

Edit project overview to modify the project summary.


The Nine Chalk Rivers project is a series of 16 restoration projects spread across nine unique chalk rivers flowing onto Norfolk’s north coast. The rivers face similar problems, most notably canalisation, disconnection from the floodplain, siltation, low flows and diffuse pollution. The projects are diverse, and include re-meandering, floodplain re-connection, silt and nutrient trapping and catchment management planning. Each project will improve the ecological health of the rivers and floodplains. To deliver these projects, Norfolk Rivers Trust is working with landowners across Norfolk as well as the Environment Agency, Natural England, The University of East Anglia, Norfolk Wildlife Trust, Norfolk Coast AONB, RSPB, The Wild Trout Trust, The River Glaven Conservation Group and various other partners.

Community Involvement – Norfolk Rivers Trust is involving communities in catchment management planning and project delivery through local conservation groups, community councils and stakeholder workshops.
