The NEON site at the Oak Ridge National Laboratory (ORNL) is a 138.1-km^2 core terrestrial field site located in the Cumberland Plateau within Anderson and Roane Counties, TN. It is encompassed within NEON's Appalachians and Cumberland Plateau Domain 7, which includes the world’s longest expanse of hardwood-forested plateau. This domain is home to some of North America's greatest diversity of fish, mollusk, and wildflower species. ORNL is managed by a combination of the Department of Energy (DOE) and Tennessee Wildlife Resources Agency (TWRA). The Domain hosts four other NEON field sites, two aquatic and two terrestrial, three of which are located in Tennessee. Remote sensing surveys of this field site collect lidar, spectrometer and high-resolution RGB camera data. The flux/meteorological tower at this site is 127’ with 6 measurement levels. The tower top extends above the vegetation canopy to allow sensors mounted at the top and along the tower to capture the full profile of atmospheric conditions from the top of the vegetation canopy to the ground. The tower collects physical and chemical properties of atmosphere-related processes, such as humidity, wind, and net ecosystem gas exchange. Precipitation data are collected by a tipping bucket at the top of the tower and a series of throughfalls located in the soil array. This site has five soil plots placed in an array within the airshed of the flux tower. Field ecologists collect the following types of observational data at this site: Terrestrial organisms (birds, ground beetles, mosquitoes, plants, small mammals, soil microbes, ticks), Biogeochemical data, and soil data. Total data products planned for this site: 119

The “Área de Proteção Ambiental das Bacias do Gama e Cabeça de Veado” (AGCV) is located in the central area of the Cerrado domain in Brazil. This area of environmental protection is important due to its strategic localization as a buffer area between urban areas and the natural environments in DF, and by harboring hydric resources from two basins. There are three contiguous conservation units located inside the AGCV: Estação Ecológica do Jardim Botânico de Brasília (EEJBB; Ecologica Station of the Botanic Garden of Brasilia), the Reserva Ecológica do Roncador - IBGE (Recor - IBGE; Roncador Ecological Reserve) and Fazenda Água Limpa (FAL; Agua Limpa Farm, the ecological and agricultural field station of the Universidade de Brasília. In addition to those there is a contiguous 5,000-h area which is well-preserved, locally known as Alpha area. This latter and the three other conservation units are located 25 km SW of Brasília, Federal District, and together comprise about 15,000 ha in the core part of the Cerrado domain. A mosaic of Cerrado vegetation, including open vegetation, typical savanna formations, and forests occur in the region.

Kopaonik is the largest and the longest mountain range in Serbia located in its central part. It is proclaimed a national park in 1981. The observatory site in Kopaonik is located in strictly protected spruce forest, on the lower distribution of spruce zone on the border zone with beach forest. The mountain is characterized by alternating climate conditions; from warmer sub-mediterranean climate in the lowest part of the mountain to cold subalpine climate in high elevation areas. Vertical profile of the mountain with different climate zones and geological diversity resulted in high habitat diversity. The largest part of the area is covered by climatologically adapted mixed deciduous and coniferous forest having obvious zonal transition. A large number of endemic and relict plant species makes Kopaonik one of the most significant biodiversity centers in Serbia. Main threats to the area besides soil erosion present logging, deforestation and tourism.

La topografía se caracteriza por llanuras, mientras los suelos predominantes están clasificados como xerosol háplico asociado a litosol y xerosol háplico asociado con litosol y planosol éutrico; estos suelos son someros (menos de 50 cm de profundidad). El tipo de uso histórico ha sido de pastoreo, aunque existen algunas áreas donde se realizó agricultura de temporal.

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 Wombat Stringybark Eucalypt SuperSite is a member of the TERN Ecosystem Processes platform (https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/), a field observatory within the Australian Terrestrial Ecosystem Network (TERN, http://www.tern.org.au/). The Wombat Stringybark Eucalypt SuperSite is located in the Wombat State Forest, Victoria, South Eastern Australia at an elevation of 713m. The site is a secondary re-growth forest that was last harvested in 1980. Dominant tree species are Eucalyptus obliqua (messmate stringybark), Eucalyptus radiata (narrow leaf peppermint) and Eucalyptus rubida (candlebark) with an average canopy height of 25 m. The understorey consists mainly of patchy grasses and the soil is a silty-clay overlying clay. The forest is managed by the Department of Environment, Land, Water and Planning and management includes selective harvesting and prescribed burning regimes. The climate of the study area is classified as cool-temperate to Mediterranean zone with cold and wet winters (May-Aug) and warm and dry summers (Dec-Feb). Key research objectives include: • What are the elements of structure, composition, functions and processes of the dry eucalypt forests of South Eastern Australia required for the sustainable management of these ecosystems? • What is the carbon sink/source strength of a dry sclerophyll forest and what is their contribution to Australia’s National Carbon Inventory? • What is the magnitude of emission and/or uptake of non-CO2 greenhouse gases, such as nitrous oxide and methane of dry eucalypt forest? • How will climate variability, drought or fire influence the ecosystem processes of dry eucalypt forest? The Dja Dja Wurrung peoples are the traditional owners at Wombat.

The Abrolhos Bank is located along the eastern Brazilian coast and is characterized by an enlargement of the Brazilian shelf (~46.000 km2), reaching approximately 200 km in width. The Abrolhos Bank encompasses three main megahabitats and a complex bathymetry. Rhodolith beds comprise the largest megahabitat, with 20,904 km² (43% of the mapped area), followed by unconsolidated sediments' megahabitat covering 19,151 km2 (39%) and by the reefal megahabitat with 8844 km2 (18%). Rhodolith beds and unconsolidated sediments are topographically less complex and form larger continuous extensions when compared to the reefal megahabitat, which is structurally complex and more patchily configured, even when examined at the regional scale.
