THE COMMUNITY WHY RESTORE RIVERS? It is part of the Norfolk Rivers Trust’s mission to gain the active participation of the community. Stakeholders help Britain’s rivers generally fail to reach “good” ecological absorb and process pollutants. This enhances water us to set objectives, keep us informed about issues on the quality. This is both a problem in itself and a sentinel quality within limits. However, very polluted rivers have less ground such as pollution and actively volunteer to make of trouble. wildlife and in turn a reduced capacity to provide such many more worthwhile projects possible. benefits.
