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 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.

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.

Dongting Lake Station (29º30'N, 112º48'E) located in East Dongting Lake in Yueyang City, Hunan Province. The station has good geographical advantage, convenient transportation, for about 180 kilometers from Changsha, the capital of Hunan Province. Dongting Lake located in the northeast of Hunan Province, the south shore of Jing River (in the middle of the Yangtze River) is the second largest freshwater lake of China.

The Camargue Biosphere Reserve covers 193 000 ha, including 50% of natural and semi-natural habitats dominated by lagoons, brackish/freshwater open and reed marshes, halophilous steppes, rangelands and fallow lands. Resilience of these ecosystems to anthropogenic influences is variable and can translate into alpha, beta and gamma biodiversity loss through ecosystem fragmentation and transition (eg, from halophilous steppes to reed marsh following freshwater input), and modification of ecosystem health state with feedbacks on ecosystem services, especially in terms of human uses (waterfowl hunting, bull grazing, reed harvesting, nature conservation). These natural ecosystems are intermingled with agro-systems of which the evolution from family to speculative farming is likely to affect biodiversity. The delta is almost completely polderized, and each year about 400 000 000 m3 of water is pumped from the Rhône to permit rice cultivation (and incidentally water management of marshes and pastures), of which 55% is pumped back to the Rhône, the rest being evacuated (when possible!) to the sea through the Vaccarès lagoon. Sea level rise, climatic variability, modification of agricultural policy (affecting rice farming areas), freshwater availability (increased penetration of the saltwater wedge from the Rhône) and underground salinisation will differently affect these ecosystems of which the dependency upon the hydro-system, primarily developed for rice production, is variable. Considering the high degree of 'artificialisation' of the delta, research and transfer activities at Tour du Valat are mostly targeting human behaviors, since we consider that management actions have currently more impact than evolution of abiotic conditions on ecosystems. Our mail goal is to foster adaptation of users, managers and decision makers to global changes. The Tour du Valat (TdV) is a private research centre located on a 2 600 ha estate (of which 1 800 ha are classified in natural reserve) in the Camargue (Rhône delta), south of France. Created in 1954 and legally recognised as a non-profit-making association, it has set itself the mission to halt and reverse the destruction and degradation of Mediterranean wetlands and their natural resources, and promote their wise use. Pioneer in producing management plans for protected natural areas, its activities are today largely oriented towards multidisciplinary research, co-constructed with or transferred to stakeholders and aimed at preserving the biodiversity, functions and services provided by ecosystems in a context of global changes. Disciplines such as hydrology, remote sensing, plant and animal ecology are combined into three main ecosystem approaches corresponding to modeling, restoration and management. Tour du Valat collaborates with managers, users, research organizations, and administrations. The Biosphere reserve provides a framework for collaborative projects across the entire Delta. Operational decisions are made by the Management Committee, the Technical Committee (made up of partners and stakeholders of the site), and the Scientific Council (involving researchers from Tour du Valat).
