ALTITUDE (meters a.s.l.): 40 m
SIZE (ha): 5300 ha
Date of establishment as LTER site: 2007
DESCRIPTION : The work is based on the former activities of Bornhöveder ecosystem research (1989-2001). Mostly monitoring, modelings regarding the interaction of structural and functional ecosystem components have been carried out. Thereafter the monitoring activates were reduced to aspects of forests dynamics in particular under atmospheric deposition loads. However, the entire project data is used for developing systemic indicator models and understanding ecosystems as interactive in the landscape context with special regard of Ecosystem Integrity. Whilst the work is mainly based on existing results and maps, monitoring date on forest in compliance with the regulations of ICP-forests manual will be available furthermore. The installed instruments will be driven by a authority specialized on forest observation. Recently, the object of research on human-environment systems has been extended, and it was carried out detailed studies on the potential of landscapes and ecosystems for the provision of ecosystem services.

Lake Maggiore
REFERENCE PERSON: Roberto Bertoni & Cristiana Callieri (National Research Council - Institute of Ecosystem Study)
COUNTRY: Italy
BIOGEOGRAPHIC REGION: Subalpine
MAIN ECOSYSTEM/HABITAT type (Eunis classification): Southern Alpine Lake / Oligotrophic lake / Holo-oligomictic lake
ALTITUDE (meters a.s.l.): 193,85 m
DESCRIPTION : Lake Maggiore is the second largest and deepest Italian lake and an important freshwater resource. It has been studied since 1940 thanks to the CNR Institute of Ecosyste Study active on its shore. The evolution of the lake passed from a pristine state to an eutrophic and again to an oligotrophic state due to the decrease of phosphorus input. This large lake is important for tourism, irrigation of rice and maize fields and for professional fisheries. Phosphorus is the limiting factor for its primary production while nitrate is the most abundant nitrogen compound in the lake. The  main effect of the ongoing climatic change on Lake Maggiore is the increase of the heat content of the lake, that affected the deep hypolimnion. It is likely that the reduction of mixing events will affect also the biota of Lago Maggiore.
Main research topic: Main research topics conducted on the lake are related to the study of the evolution of several variables from meto-climate,  to physico-chemical and biological parameters. Special interest is dedicated to the microbial component. Specific research topics are: circulation mechanisms of lake water, ecological effects of climate changes, phytoplankton, picoplankton and bacterial biodiversity, photosynthetic and dark carbon uptake, benthos diversity, zooplanktonic food web, fish stock evolution, paleolimnology.
Main LTER parameter: Long-term data sets are available of the main chemical, physical and biological parameters. LTER parameters monitored in the lake are: physico and chemical parameters, chlorophyll.

Mesta River
REFERENCE PERSON: Emilia Varadinova (Institute of Biodiversity and Ecosystem Research, Bulgarian Academy of Science Bulgaria)
COUNTRY: Bulgaria
BIOGEOGRAPHIC REGION: Sub-mediterranean
MAIN ECOSYSTEM/HABITAT type (Eunis classification): Inland surface waters.
ALTITUDE (meters a.s.l.): Altitude of Bulgarian part of the river varies between 1100- 458 m. Average altitude approximately  779 m
SIZE (ha): 0 ha
DESCRIPTION : In terms of the Water Framework  Directive 2000/60/EC ( Annex XIA), the river Mesta is located in the Eco-region 7 (Eastern Balkans). Mesta (Nestos) River rises in the Rila Mountains in SW Bulgaria and flows some 260 km trough territories of Bulgaria (129) and Greece (130) before discharging the North Aegean Sea. At the Bulgarian territory Mesta River is mountain stream with average altitude of the catchments area 1318 m what define it as a highest river valley in Bulgaria. Mesta catchments basin is situated in the zone of the European-continental climatic influence and snow-rainy. feeding. Bulgarian part of the Mesta River has 129 km length with catchments area surface 2 267 km2 and 25 tributaries along the river. The biggest one is Dospat that flows into Mesta in the Greece territory. River Mesta is regarded as one of the most natural streams found in South Europe. The status of protected areas of most of the right-side tributaries in high-mountains preserves water quality, but not the amount of potential water abstraction for increasing human needs. Left-side tributaries suffer from intensive deforestation of large areas and thus minimizing the water generation capacity of the watershed. Gradual decreasing of total water discharge following global changes and aridisation of the regions, especially in its southern sectors of the basin and watercourse.
Main research topic: Mesta river was selected as a model watercourse as far as its ecological status has been well studied for the last 30 years in terms of it hydrology, water quality, benthic invertebrate fauna, community trophic structure, and other ecological quality elements. The system offers a possibility of the ecological situation variety and river types as well as developed river system and indicative basic continuum gradients. The water ecosystem is subjected to organic pollution determining saprobic processes irrelatively pure form and wide range of the saprobity. Conditionally two main periods, determining ecological situation in the Mesta River, were described: before 1990 г., when heavy organic pollution conditions dominated, and after 1990 г. – when processes of recovering and stabilization were observed. Essential changes of the species diversity occurred after 1990 leading toward species composition enrichment with new taxa and loss of others non-adequate in the new ecological situation. As a result of decreased loading with organic matter from industrial origin water quality of the different sites is improving and entire ecological situation of the Mesta River is getting better.
Main LTER parameters: According to Water Frame Directive (2000/60/ЕU) (European Parliament and the Council of European Union 2000), all countries members of the EU have to achieve good ecological state of the water bodies. Along these lines biological monitoring is a leading and among obligatory biological parameters for water body’s quality assessment are macrozoobenthos, ichthyofauna, phytobenthos (diatoms) and macrophytes. As regards to macrozoobenthos a considerable data-massif including long-term period (1978-2012) is composed.  It should be pointed out that the available hydrological and hydrochemical (water temperature, pH, oxygen concentration/saturation, conductivity, nitrates, phosphates) parameters include 30 years period. The last three decade investigations are connected mainly with detail studies on the species diversity and trophic structure of the macrozoobenthos.Considerably fewer are the data on the other three biological elements of Mesta River, which to date has not been an object of regular and long term investigation.

Neajlov catchment
REFERENCE PERSON: Carmen Postolache and Mihai Adamescu (University of Bucharest)
COUNTRY: Romania
MAIN ECOSYSTEM/HABITAT type (Eunis classification): Arable land, Broad-leaved Forest, Built-up areas.
DESCRIPTION : The Neajlov River and its catchment are a tributary and a sub-catchment of the river Arges, which in turn is one of the main tributary for the lower Danube river stretch. The Neajlov river catchment belongs also to the four administrative units (counties) – Arges, Dimbovita, Giurgiu and Teleorman.
The main categories of land use in the Neajlov catchment are represented by the arable, forest, rural and urban built-up areas .
The landscapes structure from Neajlov catchment is dominated by man-controlled and subsidized ecosystems or agricultural ecosystems. However significant changes in the structure and management of the agricultural ecosystems occurred after 1990, when state owned and large (thousands of hectares) crop farms and animal husbandry have been replaced by small (10-15 hectares) or very small (1-3 hectares) subsistence farms. The process of restructuring the land ownership and farming systems has been accompanied by a significant land abandonment, which accounted almost 25% from agricultural land after 2000 (Postolache, C., 2004).
In addition the irrigation system and the intensive agricultural practices have been almost abandoned, which in turn diminished up to very low level the water demand and the nutrient emission into ground and surface water bodies.
The major crops in the former intensive state and collective farming systems were – corn, wheat, barley, sunflower and beet. The structure of crops has been preserved at the smaller scale and based on non-intensive agricultural practices.
The increase of arable land and the weight of agricultural ecosystems were done in the last century (in particular after 1950) by replacing the natural and semi-natural forests, wetlands and grasslands.
The total human population inhabiting the Neajlov catchment is 260400 individuals with a negative growth rate(r), after 1990, which reached the lowest level of -0.57 % in 1999.
Main research topic:
1. ecosystems analysis in terms of structure, composition and functioning of main compartments (primary producers and interactions with the soil nutrients and water availablity), polution and nutrient adition to the agricultural land and the influences on the natural vegetation (nutrients, heavy metals, gas exchanges);
2. analysis of biogeochemical fluxes, heavy metals, gas exchanges etc;
3. Interpretation and modeling at both ecosystem and landscape scale using GIS and dedicated models as well as statistic models;
4. socio-ecological analysis (starting from data collection, development of stakeholders maps, fuzzy cognitive mapping). The socio-ecological analysis has become an issue for the research and monitoring activities mainly due to the necessity to construct better scenarios for sustainable development. As consequence the database was extended in order to tackle this type of information. Main LTER parameters: Terrestrial vegetation, Litter, River hydrology, Local climate, Soil/Sediment

ALTITUDE (meters a.s.l.): 0-18 m
SIZE (ha): The total territory of the Srebarna Biosphere Reserve is 902.1 ha including the shallow holo-polymictic Srebarna Lake with slightly alkaline to neutral waters and the Danubian island Devnia. RAMSAR Site is 638 ha.
Date of establishment as LTER site: -
DESCRIPTION: The lake of Srebarna, situated in North-Eastern Bulgaria on the right bank of the Danube (440 05’’ n.l. and 270 07’’ e.l.) between the river kilometres 393 and 391, is located in a karstic depletion surrounded by three hills. The watershed basin covers area of 1,070 km2 and is formed of the basins of the rivulets Srebrenska, Babukska and Kalnezha. A hyper-eutrophic lake, the Nature Reserve, is exclusive state property, and the adjoining land tracts are private property or municipal property. Commercial fishing and mowing of Reed, Reedmace and Bulrush in the Reserve was discontinued in 1975. Since then, the natural resources have not been exploited. The Srebarna Lake was designated as a Monument of World Cultural and Natural Heritage (1983), UNESCO biosphere reserve (1977), Ramsar site (1975) and Important Bird Area (1990) because of its extremely rich ornithofauna and mainly because of the breeding of globally threatened species Dalmatian Pelican ( Pelecanus crispus), Pygmy Cormorant ( Phalacrocorax pygmeus) and Ferruginous Duck ( Aythya nyroca). During the last years the lake ecosystem underwent significant changes towards strong eutrophication and anthropogenically speeded-up succession. The main reasons were the interrupted connection with the Danube River (because of a dyke built in 1948) together with the pumping-out of the underground waters, as well as the agricultural changes and activities in the watershed basin. The restoration activities carried out in 1993-1994 and especially the canal which connected the lake with the Danube lead to the beginning of lake recovery. All these events influenced the biodiversity of the reserve. The Institute of Biodiversity and Ecosystem Research – Bulgarian Academy of Sciences (IBER - BAS) dispose with Laboratory and Education Centre in Srebarna Village near the Srebarna Biosphere Reserve. In the Laboratory are performing the hydrobiological, microbiological and ornithological studies. The exhibition in the Education Centre has three aquariums, 2 terrariums and 23 posters, which present the history and biological diversity of the reserve. The IBER - BAS have also Field Station - a house in Srebarna Village (Silistra District). In the house there is 3 badrooms, two kitchens, two bathrooms and a storage place.
