The state forest of La Reine is a humid forest of about 5000 ha located in the south of the plain of Woëvre and at the foot of the Meuse hills in France. Numerous ponds and puddles are scattered throughout the forest and it is crossed by many small, more or less natural streams. Upstream of the forest, these waterways are impacted by human activities (large-scale farming, housing without collective sanitation in particular). Since 2019, the Moselle Basin Workshop Zone has been working on the implementation of a workshop site to understand the bio-hydrogeological functioning of three of these streams, particularly in terms of natural purification. Sampling campaigns are regularly organized in the streams and in ponds.

The present proposal aims to assess how human disturbance and changes in rainfall regime affect the Caatinga ecosystem’s biota at different levels of biological organization (i.e, from populations to ecosystem level), by correlating these aspects with the theoretical reference shown in macro trends already documented in the tropics. The project will be developed in Catimbau National Park, a polygon of approximately 63,000 ha, and one of the most important protected areas in the Caatinga. The Park presents vocation for ecological studies of long-term and thus to become an LTER site due to a series of reasons: (1) it has a biological, archaeological and landscape heritage of inestimable value, (2) it shelters areas with different historical land use and anthropic disturbance on the vegetation of Caatinga, (3) there are already in place several research initiatives and training of human resources, and (4) in term of unit management aspects, logistics and infrastructure are favorable for long-term initiatives. Furthermore, the implementation and achievement of this project’s objectives are centered on: (1) establishment of a set of 30 permanent plots, (2) periodic multi-taxa inventories, (3) continuous monitoring of environmental and anthropogenic variables (4) consolidation of biological, land usage and environmental data on the basis of GIS type and (5) dissemination / transfer of information through a wide range of instruments.This proposal will be implemented by a network composed of 23 researchers supported by a number of undergraduate / graduate students, all from six national institutions and three other overseas. The main core of the graduate programs are Plant Biology, Biology Animal and Fungal Biology, all at the Federal University of Pernambuco (UFPE). In summary, the "LTER Catimbau National Park" is an important proposal and has the ability to expand knowledge about how dry biota respond to land use changes and precipitation, with all the implications that these answers may have for the management of biodiversity and the achievement of sustainable development in semi-arid regions.

Dynamics of alpine tree line has been reported from several mountain ranges in Europe, in North America, New Zealand as well as in the Alps (Grabherr et al. 1994). This led to the formation of the GLORIA (Global Observation Research Initiative in Alpine Environments) project, dedicated to initiate a global indicator network towards research on the effects of climate change through an international co-operation. Indian part of Himalaya was not having any site towards this mission till 2013. Therefore, based on some Indian studies which also indicated this trend in more pronounced manner, the need of having Indian network was felt. It was in this context as a part of network project across the Indian Himalayan states under the banner of HIMADRI (Himalayan Alpine Dynamics Research Initiative) a long-term monitoring site was established in Kashmir Himalaya at Gulmarg, a famous hill resort. This particular work plan (TeaComposition initiative) is conducted at this selected HIMADRI site. Gulmarg lies on the north east side of the Pir Panjal Range and is about 60 kms west of Srinagar city. It encompasses the upper catchment area of Ferozpur Nullah and the forests that surround the Gulmarg meadow. The vegetation in Gulmarg mainly comprises of coniferous temperate mountain forests of Blue Pine (Pinus Wallichiana), sub-alpine forests of Silver Fir (Abies pindrow) and Himalayan Birch (Betula utilis), followed by alpine scrub and meadows.

Hailun Agricultural Ecological Station located in Hailun city, Heilongjiang province, was established in 1978, briefly named Hailun Agro-ecosystem Station. The main research fields at that time were the optimal management of agriculture and advanced technology utilization in agricultural production. Chinese ecosystem research network(CERN) established in 1988 selected Hailun station as one of its components. The objective of Hailun station was to study the agro-ecosystem and sustainable development of agriculture in black soil zone in Northease China. Also, Hailun station was considered as one of components, when national field research net was built in 2005.

Děvín is a considerable site of forest and non-forest ecosystems of the warmest part of the Czech Republic. Due to heterogeneous geomorphology, it comprises a range of habitat conditions and vegetation types. Forests cover about 3/4 of the area and they are formed mainly by oak-hornbeam wood, thermophilous oak wood, and ravine wood. The forests of Děvín were strictly managed as a coppice in the past. The oldest records are available from the late 14th century. The cutting period was as short as 7 years in the Middle Age and then gradually increased to 15–25 years during the 17th–19th centuries. A reason of the coppice management was the need of firewood. This probably led to a dominance of the large-leaved lime (Tilia platyphyllos), which stands regular cutting and quickly re-sprouts. The traditional management was abandoned in the 20th century, a nature reserve was declared in 1946, and later even a game preserve was established; the latter, however, was cancelled in the 1990s. The forest has been gradually transformed to a high forest and its age has increased to the today’s average of 70, sometimes over 120 years. The dramatic change in the management has caused a large change in ecological conditions. Light woods, hosting many species occurring in light- and warm-demanding conditions, have shifted to mesic, i.e. moister and nutrient-richer forests than ever before. A marked decrease in diversity in forest understorey has been a consequence. This trend was revealed by a comparison of nearly 200 vegetation plots from 1953–1964 with their 2002–2003 replicates, i.e. after 40 to 50 years. A similar comparison is available for soils with 34 repeated pedological profiles. The aim of the present management is to restore coppices with partial preservation of some stands in a non-intervention regime. A set of 80 permanent plots has been established in 2008 in order to monitor the consequent environmental and vegetation changes, as well as diversity of invertebrates, with a monitoring period of 5–10 years.

The Transetto Senigallia-Susak is a transect of sampling stations located in the Northern Adriatic Sea. The IRBIM-CNR in Ancona and the Politechnical University of Marche collects from the end of years 80s physical, chemical and biological data. This is an excellent observing site to analyze the characteristics of water masses entering and leaving the North Adriatic Sea and their possible modification. In the site is also located the TeleSenigallia pylon.

The Rutzendorf Experimental Station is an agricultural research site of the University of Natural Resources and Live Sciences Vienna (BOKU), belonging to the Landwirtschaftliche Versuchswirtschaften GmbH. It is representative for the productive soils managed as arable land in the Marchfeld area (Lower Austria). The soil is described as a silty loamy Calcaric Phaeozem (WRB), a Chernozem according to Austrian soil classification. Management on the farm is without livestock, no organic fertilizers are applied. The farm was converted to organic farming in the production year 2002/03. The 8-year crop rotation comprises luzerne (2 yrs), winter wheat*, grain maize, spring barley*, field peas*, winter wheat, winter rye. Cover crop mixtures are grown where indicated in the crop rotation with an asteric. Current research questions include to study (i) the long-term sustainability and productivity of the stockless organic arable system compared to a livestock-keeping system, (ii) the mitigation of climate change effects on the soil-plant system by reducing soil cultivation intensity, and (iii) the development of biodiversity following the conversion to organic farming and enhancement of landscape elements. Regularly meteorological data, crop yields and quality, physical, chemical and biological soil traits, weed species and diaspores, springtails, wild bees and other animal species are assessed. Studies have been conducted as research projects financed nationally and by the European Union, e.g. in two EIP projects.

Röbäcksdalen research station was established 1954 and contains a field station and a dairy barn. The field station offers the ability to perform field research in a variety of areas such as agricultural science, biology, agroecology, soil science and environmental science. At the infrastructure it is possible to do research in a variety of areas such as animal science, agricultural science, ecology, phenology, climatology, geochemistry, biology, agroecology, soil science and environmental science. Visitors and users of the infrastructure can get access to the land and a stream collecting drainage and surface runoff-water from the area, animals in the dairy facility, workshop, machines, measuring equipment and techniques, personnel, laboratories and working stations. All data that is gathered within the infrastructure can also be available for the user, most of with is continuously collected data, data from feeding trials, climate data, soil data, data from water samples of runoff-water, data from the catchment area around the station as well as GIS data and data from different long-term-trials. The predominant soil type at the experimental fields is sandy-silt, which is characterized by good water holding capacity and high capillarity, hence the crops seldom suffer from drought here. The humus content is high (3-6%) which means that the soil is not so dense, something that otherwise might be a problem for this soil type. Sandy soil is present in limited areas. We are active in four different locations in northern Sweden. At Röbäcksdalen we manage the station and on the other sites we collaborate with Lantmännen Lantbruk at Lännäs (Västernorrland), Torsta AB at Ås (Jämtland) and Hushållningssällskapet Norrbotten och Västerbotten at Öjebyn (Norrbotten). The dairy barn was built in 2006 and has around 105 dairy cows of the breed Swedish red. The barn can e.g. be used for feed trials and among the equipment are two Greenfeed units that measure greenhouse gases (GHG) produced by the animals. The inclusion of the barn also offers farm scale studies of e.g. production of GHG or N or P flows.

NINA Aquatic Research Station, Ims provides advanced research facilities on aquatic research, primarily focused on fish ecology

UK ECN Site. Esthwaite Water is a natural lake situated in a glacial valley and is generally agreed to be the most productive or eutrophic lake in the English Lake District. It lies approximately 65 m above sea level and has an area of 1 km2 and a maximum depth of 15.5 m. The average retention time is 90 days. The catchment area is 17.1 km 2 and the hills are composed geologically of Bannisdale slates and grits. The surrounding land is used chiefly for agricultural purposes and forestry. The lake is a grade 1 Site of Special Scientific Interest and has been a designated "Ramsar" site since November 1991. The diverse aquatic invertebrate fauna includes a number of species with restricted distributions in Britain, one of which is the flatworm, Bdellocephala punctata. The slender naiad, Najas flexilis, which is listed as Nationally Scarce, has been found in Esthwaite Tarn. Artificial enrichment of the lake occurs by input from the Hawkshead Sewage Treatment Works (which has operated a continuous programme of phosphate stripping since 1989) and originally from effluents from the fish farm which used to be situated towards the south of the lake. The lake undergoes summer stratification with oxygen depletion regularly below 7 m and sometimes as shallow as 5 m. The phytoplankton tends to be dominated by diatoms in spring and by cyanobacteria for much of the summer.
