Anthropogenic modifications to water regimes are one of the main factors threatening the stability and existence of floodplain forests. This study presents an analysis of topsoil biogeochemistry withi...
Extensive soil sampling and screening assessment of ecosystem risks combined with a multidimensional statistical analysis were used to estimate and spatially characterize the ecosystem risks stemming ...
Ecological functions of a black alder riparian forest (Aegopodio-Alnetum glutinosae) as capacities for the provision of ecosystem services were analysed and indicated by an inductive (bottom-up) appro...
Floodplain forests have traditionally been managed using the coppice-with-standards silvicultural system for centuries. After abandoning this silvicultural system approximately in the 1950s the crown...
Knowledge of the structure and diversity of bird populations in forest ecosystems is important for the conservation of forest biodiversity.
The paper reports the results of a study focused on ornithocoenoses of floodplain forests in Litovelské Pomoraví locality (Czech Republic). The edge effect on diversity of the bird community is discus...
The paper analyzes the effect of whole-area site preparation by ploughing and of alternate field and forest crops on the understorey, soil biological activity and physical and chemical characteristics...
In order to determine the environment carrying capacity in terms of biomass production utilizable by game 360 representative sample plots (1 ?1 m) were laid out in the growing season on the basis of t...
This paper presents the results of an analysis of the changes in the fragmentation and ecological stability of the floodplain forest geobiocoenoses in the Protected Landscape Area Litovelsk?Pomorav? C...
At present, the coppice-with-standards system has become so rare in floodplain forests that it is considered a natural monument. In 1990, the coppice-with-standards system was not recorded in the terr...
Like in other types of forests the greatest changes in the soil of floodplain forest stands occur during their regeneration. These changes are manifested as changes in the content and dynamics of orga...
The paper deals with historical development of floodplain forests in the area of Vrapač National Nature Reserve in the floodplain of the Morava River (Protected Landscape Area Litovelské Pomoraví...
The paper characterizes the natural conditions and current state of floodplain forests in the area of Litovelské Pomoraví and proposes the protective management of the area in accordance with the Euro...
Since the mid-1970’s, the landscape around the confluence of the Morava and Dyje rivers has undergone substantial changes related to the drop of water table caused by water management measures underta...
