The study plot was established by the Institute of Forest Ecology (Mendel University in Brno) in 1968, namely in connection with the UNESCO International Biological Programme (IBP) and the UNESCO programme “Man and the Biosphere” (MAB). Research was aimed at the primary production, element and water cycling and the secondary production of invertebrates, birds and small mammals. It refers to a semi-natural floodplain forest free of management measures characterized by the Ulmeto-Fraxinetum carpineum forest type group. Dominant tree species are as follows: Fraxinus excelsior, Quercus robur, Populus nigra, Tilia platyphyllos, and Acer campestre. In consequence of flood control, the local floodplain forest was affected by changes in the water regime (absence of natural floods, fall of the groundwater table) from 1972. In the course of the 1970s and 1980s, it resulted in the insufficient supply of water. Since the 1990s, revitalization measures have been carried out (increasing the ground water level by means of channels) for improving forest health. Changes in the water regime have resulted in the improving condition of the floodplain forest ecosystem that has been documented owing to LTER on the site. Following research activities are carried out there: (i) monitoring selected parameters of the stand microclimate and mesoclimate, (ii) evaluating the moisture balance in the forest ecosystems, (iii) evaluating the water regime and moisture conditions of the floodplain forest ecosystem, (iv) evaluating temperature and moisture conditions, (v) research into the water relations of trees, (vi) evaluating long-term changes in the synusia of small terrestrial mammals of the floodplain forest, and (vii) evaluating decomposition processes.

A small watershed that collects floods and run-off. The lowest place is home to a (relativity) dense Acacia savana. The slopes are completely bare. The wadi is covered with alluvium resting on a 6 m layer of red surface of late Pleistocene, which includes silt, clay and fine sand. Rainfall is 30 mm

The study plot was established by the Institute of Forest Ecology (Mendel University in Brno) in 1968, namely in connection with the UNESCO International Biological Programme (IBP) and the UNESCO programme "Man and the Biosphere" (MAB). The study plot is carried out in the natural forest region 30 – Drahanská Vrchovina upland (Drahanský bioregion, 1.52) about 1 km west of the village of Němčice in the Czech Republic on the modal oligotrophic Cambisol (KAmd´) of a fir-beech forest vegetation zone (4 FVZ) with forest type 5S1 – Abieto-Fagetum mesotrophicum with Oxalis acetosella (4AB3 – Fageta quercino abietina, union Luzulo-Fagion, association Luzulo-Fagetum) at an a altitude of 600–660 m at sites of autochthonous mixed forests. Research is aimed at ecological aspects of the transformation of spruce monocultures and optimation of management procedures at the application of sustainable management in forests. Recently, research is aimed at possibilities of the adaptation of forest stands on effects of an expected climate change. The main oriented research in present is: (i) study of mesoclimate and microclimate, (ii) evaluation of water balance, (iii) phenology of tree species, (iv) study of biogeochemical cycle (carbon, nitrogen, sulphur), (v) study of decomposition and soil processes, and (vi) evaluation of biodiversity.

The site is a revitalized young steppe habitat patch, dominated by fescue (Festuca rupicola). The average altitude is around 100 m. The site is a grazing spot and it was recently used for the reintroduction of the European ground squirrel (Spermophilus citellus) to the area after 70 years. Other important species present at the site include Vojvodina blind mole rat (Nannospalax (leucodon) montanosyrmiensis) and Spring meadow saffron (Bulbocodium versicolor).

The Wüstebach catchment is located in the Eifel National Park and covers an area of 38.5 ha, with mean altitude of about 610 m. The geology is dominated by Devonian shale, which is covered by a periglacial solifluction layer of about 1–2 m thickness. Cambisols and Planosols have developed on the hillslopes, whereas Gleysols and Histosols have formed in the valley. The main soil texture is silty clay loam and the litter layer has a thickness between 0.5 and 14 cm. The mean annual precipitation is about 1200 mm. Norway Spruce planted in 1946 is the prevailing vegetation type. During late summer/early autumn of 2013, trees were almost completely removed in an area of 9 ha by the national park forest management in order to promote the natural regeneration of near-natural deciduous forest from spruce monoculture forest.

Dong Cao is a small agricultural catchment (47 ha) of northern Vietnam, located at 70 km from Hanoi, in a sloping land environment. The objective is to monitor the impacts of land use changes (from cassava to fodder and tree plantations) and possible climate changes upon hydrological and sedimentary fluxes and budgets. The catchment has an elevation of 125 m to 485 m and slopes range from 15 to 120%. Monitoring devices include an automatic meteorological station, and weirs to monitor discharge, suspended sediment and bedload. More information is available on https://mtropics.obs-mip.fr/ and in the following paper: Valentin, C., et al., 2008.

The site is located in Clocaenog Forest in North East Wales (53o 03’ 19’’N -03o 27’ 55’’ W). It is a typical upland west-atlantic moorland, dominated by the evergreen shrub Calluna vulgaris (heather). Heather makes up >60% of the plant biomass at the site, but Vaccinium myrtillus and Empetrum nigrum are also present.
