Effect of Newly Created Water Reservoirs on Agricultural Landscape Stability

摘要

The paper presents an assessment of the effect of three water reservoirs near the Nienawiszcz village (Western Poland) on the improvement of landscape structure and stability. The reservoirs were reconstructed in the years 1999-2012 in places where ponds and post-glacial lake were present in the past. A number of works were also carried out to organise and enrich the landscape around studied area, which is a part of real estate. The research carried out in the years 2013-2015 included valorisation of the natural environment, determination of the ecological and spatial model of the landscape and assessment of landscape stability according to the criterion of the connection network. Valorisation of the natural environment has shown the dominance of areas with outstanding and high natural values (class I and II). Regenerated water reservoirs and wood plantings increased the number and diversity of landscape islands and the connections between them, which additionally improved the stability of the landscape. Water reservoirs and numerous landscape activities in this area significantly influenced the increase of biological diversity as well as the diversity and functionality of the landscape.
