Hardwood floodplain forests of lowland rivers in the temperate zone of Europe represent important refugia for biota in the cultural landscape. Most of these habitats that are in near natural state are included in the system of protected areas and ecological networks. This paper presents the results of an innovative method for the assessment of hardwood floodplain forest management strategy. This method is based on combining the analysis of historical development of the forest ecosystem with the growth simulation model of the forest. The method allows us to understand (explain) the current state of the hardwood floodplain forest ecosystem and to predict its future development taking into account the applied forest management strategy. Application of this method is promising especially in protected areas because it allows us to assess the suitability of the chosen strategy that is included in the protected area management plan. The research was conducted in the area of ‘Bahna’ in Litovelské Pomoraví protected landscape area (Czech Republic). The current management strategy applied on the hardwood floodplain forest ecosystem in the study site is based on a strict non-intervention protection regime. Historical research of the forest ecosystem showed that the studied floodplain forest habitat is a relic of coppice with standards system and thus is the result of intensive forest management in the past. Growth simulation model showed that in the future 40 years the assessed management strategy will not lead to significant changes in the structure or diversity of the tree layer. Considering the conservation objectives of the reserve (maintenance of biodiversity and the present character of the forest ecosystem dominated by ash and oak), the current management plan does not require any significant corrections. The presented results can be applied in discussions about optimal management strategies in protected areas containing hardwood floodplain forest ecosystems, which belong to priority natural habitat types in the Natura 2000 network.

W artykule omówiono rezultaty sześciomiesięcznego okresu konsultacji społecznych dotyczących dokumentów planistycznych podstawowych dla procesu planowania w gospodarce wodnej na lata 2009–2015. W grudniu 2008 roku zostały one przedstawione przez Prezesa Krajowego Zarządu Gospodarki Wodnej do oceny społeczeństwa na obszarze całego kraju, natomiast omówienie procesu konsultacji w artykule ograniczone zostało do obszaru działania Regionalnego Zarządu Gospodarki Wodnej w Krakowie. Poprzedza je omówienie struktury i zawartości planów gospodarowania wodami dla obszarów dorzeczy oraz programu wodno-środowiskowego kraju. Konsultacje przedstawiono w podziale na cztery podstawowe kategorie – rezultaty spotkań konsultacyjnych, wyniki badan ankietowych, stanowiska ciał doradczych dyrektora RZGW w Krakowie, a także uwagi samego RZGW, instytucji administrującej regionami wodnymi Górnej Wisły, Dniestru i Dunaju.

The article presents the results of six-month public consultations on the basic planning documents for the planning process in water management for the years 2009–2015. The documents were presented for assessment to the general public in Poland by the President of the National Water Management Board in December 2008, whereas the discussion about the consultation process was limited to the area of activity of the Regional Water Management Board in Krakow (RZGW in Krakow). The article discusses the structure and content of the river basin management plans and the programme of measures. The latter consultation process results are divided into four basic categories: results of consultative meetings; results of opinion surveys; positions taken by advisory bodies to the Director of the RZGW in Krakow; and comments coming from the RZGW in Krakow, an institution which manages the water regions of the Upper Vistula, the Dniester and the Danube rivers.
