Tag hinzufügen | Zusammenfassung: | Loch Leven has suffered from periodic cyanobacterial blooms for many years, largely, as a result of substantial amounts of phosphorus entering the loch, combined with a relatively low flushing rate and a favourable light-climate. The blooms have a direct impact on the various users of the loch, and in terms of conservation interest, reduce light penetration into the water, reducing macrophyte growth, with associated impacts on macro-invertebrate, fish and bird communities. Since the 1970s there has been an action programme to improve the ecology and water quality of Loch Leven aimed, primarily, at reducing the intensity and frequency of phytoplankton blooms, and enhancing water clarity by reducing the loadings of phosphorus to the loch. This report provides a synthesis of all water quality monitoring undertaken at Loch Leven up to and including 2001, together with published ecological data from a variety of sources. The review aims to examine long-term patterns of change in key water quality parameters in response to the reduction in external phosphorus load, and evaluate any evidence of ecological recovery. In addition to this, the report explores the role of each parameter in the understanding of changes in water quality, and makes recommendations for future monitoring and management. |
