Abstract:
For several years there has been much local concern over low flows and low water levels In the River Kennet and the associated deterioration in ecological Interest. One issue highlighted in the 'River Kennet Catchment Management Plan, Consultation Report (NRA 1993) was changes In the abundance and community structure of aquatic weeds. Perceived changes included the increasing prevalence of terrestrial plants in the headwaters, reduction in the abundance of Water-crowfoots (Ranunculus spp.) and proliferation of filamentous algae (eg Cladophora sp.)-and Water-cress (Nasturtium officinale). As a result of these perceptions, Sir William Halcrow and Partners Ltd (Halcrow) was commissioned by the NRA in August 1993 to undertake an investigation of weed growth and weed management practices in the Upper Kennet. The project consisted of two main components: a baseline survey of aquatic weeds; a review of problems and management practices. Analysis of the baseline survey, carried out in autumn 1993, showed that different river reaches were characterised by different macrophyte communities.
