Individual papers present data collected over 14 years, which provides an opportunity to understand the natural dynamics in a system with very little direct influence from human activities. The results indicate a level of variation that should be expected in natural systems, and provides a solid basis for a discussion of the best approach to the monitoring of biological diversity and environmental factors in rivers and lakes.
The volume is aimed at researchers working with watershed management and aquatic sciences. It provides useful information and experiences of particular relevance to the implementation of the EU Frame Directive for Water.
