The Upland Heath Swamps Plot Network is located in the Dharawal National Park, near Sydney, NSW. Sampling of vegetation is stratified along the soil moisture gradient and across the range of structural variability in the vegetation. Thus, three categories of soil moisture and three categories of vegetation structure (based on the height and form of shrubs) are sampled in a factorial design at 60 sites in upland swamps scattered throughout the study area (Keith & Myerscough 1993). Temporal visits are conducted every 5 years or when fires occur. Between 2012 and 2018 the Upland Heath Swamps Plot Network was a member of Long Term Ecological Research Network (LTERN), Australia, a facility of the Australian Government's Terrestrial Ecosystem Research Network (TERN).

Lake Cerknica is intermittent lake appearing at the bottom of closed depression Cerkniško polje extending on the area of 38 km2. The karst features are associated with carbonate rock, both with limestone and dolomite. About 80 % of inflow consists of karst and only 15% of surface waters. The outflow is completely karstic. In spring and usually late in autumn the lake reaches normal level 550 m a.s.l., covering the area of 26 km2. Polje is flooded for 9 and dry for about 2 months, usually in summer. Lake Cerknica is a highly diverse ecosystem that changes in time and space. Vegetation pattern shows clear zonal distribution that depends on extent and frequency of flooding. The lake supports rich fauna with many endangered species, providing temporary shelters and food for protected large carnivores, such as brown bear, wolf, lynx and numerous species of water birds. In recent decades, flood and drought events have become increasingly irregular altering processes and conditions for many species.

The Desert Ecology Plot Network is located in the Simpson Desert in central Australia. The vegetation in the study region is dominated by hard spinifex (Triodia basedowii E. Pritz), with scattered small woodlands of Georgina gidgee (Acacia georginae F.M. Bailey) interspersed throughout (Figure 9.1). The long-term plots for which data are provided as part of LTERN infrastructure are all located within the spinifex hummock grasslands, but additional survey plots, situated in gidgee woodlands, exist and have been surveyed since 2006 and are revisited whenever possible. Temporal visits are conducted annually. The Desert Ecology Plot Network was a member of Long Term Ecological Research Network (LTERN), Australia, a facility of the Australian Government's Terrestrial Ecosystem Research Network (TERN).

The Kellogg Biological Station (KBS) is located in southwest Michigan in the eastern portion of the U.S. cornbelt, 50 km east of Lake Michigan in the SW corner of the state (42° 24′ N, 85° 24′ W, elevation 288 m). Annual rainfall at KBS averages 1,005 mm/y with about half falling as snow; potential evapotranspiration (PET) exceeds precipitation for about 4 months of the year. Mean annual temperature is 10.1 °C. KBS is 1600 ha of cropping systems, successional communities, and small lakes. Surrounding KBS is a diverse, rural-to-semirural landscape typical of the U.S. Great Lakes and upper Midwest regions. The diversity of land use, soil and vegetation types, and aquatic habitats within a 50-km radius of the Station is high. Most of southwest Michigan is on the pitted outwash plain of the morainic system left by the last retreat of the Wisconsin glaciation, circa 12,000 years ago. Soils in the area developed on glacial till, and include well- and poorly-drained alfisols, mollisols, and entisols. Most regional soils are sandy loam and silty clay loam of moderate fertility, principal Station soils are Typic Hapludalfs. Land use around KBS ranges from urban (Kalamazoo, with a metropolitan population of 180,000, is 20 km south of the Station) to rural; vegetation ranges from cultivated and early successional old fields to older growth oak-hickory and beech-maple forests; and aquatic habitats include more than 200 bodies of water of different morphometries, alkalinities, and degrees of eutrophication within 50 km. Cropping systems in the area are typical of the U.S. cornbelt — mainly corn/soybean rotations with wheat of varying importance, and alfalfa an important forage crop. KBS yields are typical of non-irrigated yields elsewhere in the North Central Region. KBS LTER research is carried out in a variety of experimental systems. The most important of these is the Main Cropping System Experiment (MCSE), which was started in 1989 and consists of 11 different cropping systems or successional plant communities, ranging from annual corn-soybean-wheat rotations to late-successional deciduous forest. All communities are replicated within the landscape.

The Connell Rainforest Plot Network is a member of Long Term Ecological Research Network (LTERN), Australia (http://www.ltern.org.au), a facility of the Australian Government's Terrestrial Ecosystem Research Network (TERN), (http://www.tern.org.au). The long-term forest dynamics plot at O'Reilly's is located in the subtropical rainforest near O’Reilly’s Guest House in Lamington National Park, 65 km south of Brisbane. It consists of two 1-ha plots spaced approximately 600 m apart, but for analyses they have always been treated as a single unit. This plot has never been logged, but some selective logging has occurred just outside the plot boundary. Temporal visits occur between 1 to 6 years.

SITES Lönnstorp research station is situated in the Scanian agricultural landscape between Malmö and Lund and has a focus on the design, sustainable development and assessment of arable cropping systems, in conventional and organic farming. The research station is available for research within ecology, agronomy, environmental science, agroecology and other disciplines. SITES Lönnstorp research station have access to 60 hectares of conventional and 18 hectares of organic farm land, mainly cultivated with annual crops, representative for agricultural practise in southern Sweden. The station is also a part of SITES, Swedish Infrastructure for Ecosystem Science. SITES is a nationally co-ordinated infrastructure for terrestrial and limnological field research. In 2016, SAFE (SITES Agroecological Field Experiment) was established at the research station. SAFE make it possible to compare four different agroecosystems, a conventional reference system, an organic system, a perennial system and an agroecological intensified system.

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.
