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 discussed and some implications for floodplain forest management are presented based on the results of investigations into changes in the bird community due to fragmentation of an originally continuous forest stand by regeneration felling, and the results of research into ornithocoenoses of the age-diversified mosaic of forest stands. Perforation of the continuous old floodplain forest by clear felling, which was investigated within this study, slightly increased the diversity of nesting birds. However, bird species typical of open cultural landscape benefitted, whose nesting was not recorded before the perforation of the originally continuous forest ecosystem.

The paper is aimed to assessment of diversity and structure of bird community in floodplain forest ecosystem. Authors present results of analyses data on bird communities obtained at two transects in the Litovelské Pomoraví Protected Landscape Area (Czech Republic) in the period 1998–2012. Research of bird communities was carried out using the point-count method. The article deals with qualitative and quantitative representation of breeding bird species, including their relation to habitat type (closed floodplain forest, ecotone). Altogether 63 breeding species were recorded at the Vrapač transect and 67 at the Litovelské luhy transect, respectively. To be able to detect all recorded species, 11 out of 14 years of monitoring were needed at the Vrapač transect and all 8 years of monitoring at the Litovelské luhy transect, respectively. Authors show that the values in dominant bird species change significantly among the particular census dates within one season, mainly with respect to their activity and detectability. Results are discussed in the frame of sustainable forest management in floodplain forest ecosystems. The presented article can promote to discussion aimed to management strategy for floodplain forest ecosystems, which ranks among natural habitat types of Community interest protected under the Natura 2000 European network.

A Proposed Target State for a Floodplain Forest Ecosystem Within an Ecological Network, with Reference to the Ecological Requirements of an Umbrella Bird Species: The Common KingfisherThe present day cultural landscape of Europe is comprised of an ecological network of corridors and core areas (biocentres). This article proposes the use of umbrella species to define the target state of an ecosystem in a floodplain biocentre of the European Ecological Network. The umbrella species used were chosen to represent typical bird species of forested floodplains. Case studies were developed in the Litovelské Pomoraví Protected Landscape Area, a Bird Area in the Czech Republic.

The annual flooding in the Amazon basin transforms the understory of floodplain forests into an aquatic environment. However, a great number of non-aquatic bird species occupy the understory and midstory of these forests. In general, these birds are thought to be sedentary and territorial, but the way they adapt to this dramatic seasonal transformation has never been described in detail. In this study, we describe avifaunal strategies to cope with seasonal flooding in the lower Purus region, central Amazonia, Brazil. We conducted focal observations of five insectivorous species occupying the lowest forest strata in two types of floodplain forest (black- and whitewater) during the low- and high-water seasons. For each observation, the height of the bird above the substrate (ground or water), its vertical position in the forest, and vegetation density around the bird were noted. All species remained present in the floodplain forests during the two seasons and were not recorded in adjacent unflooded (terra firme) forest. In general, birds migrated vertically to higher forest strata and most species (three of the five) occupied similar vegetation densities independent of water level. Despite the tendency of all species to rise in relative vertical position at high water, there was a reduction in height above substrate for four of the five species, suggesting that their position relative to water was not an important microhabitat element for them. Responses were similar in the two floodplain forest types. It is likely that the decrease in available space during the flood, combined with similar vertical displacement in arthropods, leads to increased prey density for understory insectivorous birds and permits year-round territoriality without major habitat shifts.

Abstract This paper presents an evaluation of full-area floristic investigation of floodplain forests in Soutok forest district (Židlochovice Forest State Enterprise) based on an individual forest stand inventory. The study area encompasses 5103 ha of forests, where 1186 segments were inventoried, and 71 223 single records about presence of vascular plant species were done. We found 761 taxa (species, subspecies and hybrids), out of which 655 were herbs, 106 woody plants, 156 were endangered species and 177 adventive species. The average area of a segment was 4.3 ha. The mean number of species per segment was 64.42 in a range of 4–180.

AbstractMachar I.: Applying landscape ecological principles in sustainable forest management of the floodplain forest in the temperate zone of Europe. Ekologia (Bratislava), Vol. 32, No. 4, p. 369-375, 2013.European floodplain forests of the temperate climatic zone are an example of an ecosystem in the cultural landscape characterized by an exceptionally high biodiversity. In this usually heavy deforested landscape of the Central and South European river floodplains, which are subjected to intensive agricultural use, the preserved ecosystems of floodplain forests represent important refuges for biotic biodiversity and are invaluable for the ecological landscape stability of the entire floodplain and the wider river basin. Unlike other Central European communities, whereby constant ecological conditions of habitats tend to be preserved even upon changes in ecosystem, the floodplain forests are characterized by a long-term continuous development of ecotopes, conditioning the complex interconnected succession series of ecosystem. The ecological floodplain phenomenon is created by fluvial landscape processes and the conservation of the natural development dynamics of the said fluvial landscape processes is essential for its protection. The landscape structure of floodplain forests is significantly affected by forest management measures, including regeneration methods, silvicultural measures and felling. Floodplain forest management radically affects the biodiversity of the given ecosystems which are listed among habitats of European concern in the Natura 2000 network. Since understanding of the biological nature of forest ecosystems is essential for landscape and ecological planning and sustainable forest management, it is imperative to study ecological processes taking place in the various floodplain forest biotopes in order to be able to define the principles of their management. This article aims to contribute to the process of formulating principles of biodiversity protection and the management strategies for floodplain forest ecosystems, while applying some theories and methods of landscape ecology. The Results section of the article comes in the form of case studies for each topic and draws on original data which were published in the scientific journals or presented at scientific conferences (see References). Some of the presented case studies focus on the Protected Landscape Area Litovelske Pomoravi.

The floodplain forests of lowland rivers in the temperate zone of Europe are an important biota refuges in the cultural landscape. Most of these forest ecosystems are included to the national systems of protected areas and ecological networks. The paper deals with innovative method for assessment of management strategy for hardwood floodplain forest ecosystems. The presented method is based on a combination of results from historical research with the application of growth simulation model. This method enables to predict a future development of the forest ecosystem studied and assess the forest management strategy. This can be a useful tool for correction of management plan of protected area. The method was applied in study site Vrapac National Reserve within the Morava River basin (Litovelske Pomoravi Protected Landscape Area, Czech Republic).

Are there any common patterns in the transition processes from traditional and more or less sustainable forest management to exploitative use, which can regularly be observed both in central Europe and in the countries of the South (e.g. India or Indonesia)? Attempts were made with a time-space-model to typify those force fields, in which traditional sustainable forest management is undermined and is then transformed into a modern type of sustainable forest management. Although it is unlikely that the history of the North will become the future of the South, the glimpse into the northern past offers a useful starting point for the understanding of the current situation in the South, which in turn could stimulate the debate on development. For instance, the patterns which stand behind the conflicts on forest use in the Himalayas are very similar to the conflicts in the Alps. In the same way, the impact of socio-economic changes on the environment – key word ‹globalisation› – is often much the same. To recognize comparable patterns can be very valuable because it can act as a stimulant for the search of political, legal and technical solutions adapted to a specific situation. For the global community the realization of the way political-economic alliances work at the head of the ‹globalisationwave›can only signify to carry on trying to find a common language and understanding at the negotiation tables. On the lee side of the destructive breaker it is necessary to conserve and care for what survived. As it was the case in Switzerland these forest islands could once become the germination points for the genesis of a cultural landscape, where close-to-nature managed forests will constitute an essential element.

Forest and climate change in the inner-Alpine dry region of Visp Over the past decades, observed increases in temperature have been particularly pronounced in mountain regions. If this trend should continue in the 21st Century, frequency and intensity of droughts will increase, and will pose major challenges for forest management. Under current conditions drought-related tree mortality is already an important factor of forest ecosystems in dry inner-Alpine valleys. Here we assess the sensitivity of forest ecosystems to climate change and evaluate alternative forest management strategies in the Visp region. We integrate data from forest monitoring plots, field experiments and dynamic forests models to evaluate how the forest ecosystem services timber production, protection against natural hazards, carbon storage and biodiver-sity will be impacted. Our results suggest that at dry low elevation sites the drought tolerance of native tree species will be exceeded so that in the longer term a transition to more drought-adapted species should be considered. At medium elevations, drought and insect disturbances as by bark beetles are projected to be important for forest development, while at high elevations forests are projected to expand and grow better. All of the ecosystem services that we considered are projected to be impacted by changing forest conditions, with the specific impacts often being elevation-dependent. In the medium term, forest management that aims to increase the resilience of forests to drought can help maintain forest ecosystem services temporarily. However, our results suggest that relatively rigid management interventions are required to achieve significant effects. By using a combination of environmental monitoring, field experiments and modeling, we are able to gain insight into how forest ecosystem, and the services they provide, will respond to future changes.
