Abstract

Restoration of severely eutrophic, shallow lakes often involves a step by step treatment, starting with control of catchment nutrient inputs and internal nutrient loading, followed by biomanipulation and finally the stabilisation of a macrophyte dominated lake. In this paper, the restoration strategy of Barton Broad is presented. As this is the largest and most complex of the lakes in Broadland to restore, the nature of the restoration strategy is derived from the combined experience of research, monitoring and small scale restoration projects elsewhere. Some practical difficulties and uncertainties are identified within each of the restoration ‘steps’. The need for careful assessment of restoration targets, a catchment approach and collaboration with local people are emphasised.
