Bab - Slovakia
Thermophilous deciduous woodland
The Bab forest (66 ha) was selected as an example of a lowland deciduous broad-leaved forest on loess for ecosystem research in the International Biological programme (IBP) in 1967. More than 60 researchers performed a comprehensive ecosystem research at the site within IBP and MaB programmes in 1967-1975. This period finished by production of syntheses in micro-meteorology and micro-climate, soils, soil microbiology, ecophysiological processes of plants (photosynthesis, water relations, mineral nutrition), primary productivity, nutrient cycles, water circulation, and secondary productivity. The ecosphisiological studies continued in 1975-1980, later the research was focused to plant population biology and alien plants invasions. The ecosystem research was re-established in 2007. The inventory of shrub and trees, herb vegetation, selected animal groups allowed identification of changes during 40 years caused probably by the climate changes and anthropogenic disturbances. The differences in decomposition of selected native and invasive plant species were assessed. The biomonitoring of the air pollution was done using mosses as indicator organisms. Now the research is focused to dynamics of forest ecosystem (vegetation, selected invertebrate groups, small mammals) and impact of forestry management (clear-cuts) to structure and dynamics of forest ecosystem. The multisite trampling experiment (ALTER-Net) and tea decomposition experiment (ILTER) were/are performed at the site.
General Characteristics, Purpose, History
The ecosystem research in Bab forest in period of IBP and MaB programme (1967-1975) was aimed in obtaining knowledge on mechanisms of production processes, identification of principles of ecosystem functioning and interactions between its components. Later (1975-1980) the ecophysiological research of palnt functional groups continued. After 1980, the research was limited to several topics, including primary production, plant population dynamics and invasions of alien species. More complex research was re-established in 2007 aiming at identification of changes in the structure and composition of forest ecosystem (vegetation and selected invertebrate groups) and impact of forestry management (clear-cuts) to structure and dynamics of forest ecosystem. The site was used for the ALTER-Net multi-site trampling experiment and the ILTER tea bag decomposition experiment.
The site was established in 1967 as part of the International Biological Programme (IBP), later supported by UNESCO Man and Biosphere Programme (MaB). After interruption, research started again in 2007. The ALTER-Net multi-site experiment was performed at the site and theTeaComposition (global litter decomposition study) experiment was established in 2016.
