Summary:

The following study concerns an assessment of ways of the littoral zone management in both small and middle lowland watercourses on the composition of hydromacrophytes in water communities. The research was performed between 2007 and 2012 in 20 study sections located in Lower Silesian watercourses. The research included an assessment of the development of the littoral zone and identification of water hydromacrophytes and determination of the level of their bottom coverage. Each study section had a Shannon-Wiener biodiversity, Pielou evenness and species shortage indexes calculated.
Results of the following study indicate that ways of using the littoral zone have a significant influence on analyzed vegetal indexes. The highest values were observed in study sections where littoral zones were such as:. uncultivated lands such as wetlands, bushes and tall herbs. While the lowest observed values in all compared indexes were noted in forest sections.
