dc.description.abstractThe article presents the complex processes of renaturalisation in the middle part of the Kamionka valley in the Poznańskie Lakeland. They are the result of socio-economical and landscape changes, which occured in the study area in the last 100 years - mainly land use changes due to withdrawal of former intense human activity, abandonment of agriculture and development of secondary vegetation succession. The main aim of the research was to analyse the reaction of natural environmental system to changes of the intensity of human impact, as well as to recognize the persistence in the landscape of former anthropogenic landforms. The research method comprised: field investigations, mainly detailed geomorphical mapping (with special focus on anthropogenic landforms), analyses of plant communities and extent of secondary succession, as well as analyses of archival sources, mainly topographic maps from various periods and air photographs. The study proved a strong relationship between the changes of land-use pattern and their environmental effects both on biotic and abiotic elements of the ecosystem. A substantial increase of forested areas in the last 100 years, together with an activity of new introduced fauna species like beaver, influenced the type and intensity of other environmental and morphological processes. The following changes are observed in the study area: reduction of erosion on slopes, increase of water retention in the drainage basin, increase of organogenic accummulation, local increase of sinuosity of stream channels, fastening of development of denudational valleyheads and spring sapping. Additionally, the anthropogenic landforms, connected with former human activity, dissappear gradually from the landscape, mainly due to denudational processes and encroachment of secondary vegetation succession. Further development of renaturalisation of the study area is likely to become locally more diverse. However, its progress and environmental results are highly dependent on the protection strategy and policy, which will be conducted by the Pszczewski Landscape Park and by the regional forestry council.pl_PL
