Tönnersjöheden and Skarhult experimental forests are situated in the nemoral/nemo-boreal zone closed to the Atlantic sea in South Sweden. Tönnersjöheden (1143 ha) was established as an experimental forest in 1923 with the original aim of studying ecosystems in transition from low productive broad-leaved forests and open Calluna heath-lands to conifer dominated forests. Skarhult (180 ha) was opened as an experimental forest in 1989 with a main focus on management and ecology of broad-leaved forest stands. Forests at Tönnersjöheden are dominated by old growth broad-leaved stands with long continuity, first and second rotations of planted coniferous stands and a number of planted stands with exotic tree species. Forests at Skarhult are dominated by naturally regenerated and planted pure and mixed broad-leaved forest stands of European beech (Fagus sylvatica L.), common oak (Quercus robur L.) and ash (Fraxinus excelsior L.). Research and monitoring activities cover a broad range of basic and applied subjects in the field of forest and forest related environmental sciences. The experimental forests are well-documented and well-described concerning history, climate, soils, vegetation and forest stands.

The tidal flats between Den Helder in the Netherlands and Esbjerg in Denmark are the largest continuous tidal flats in the world and one of the last areas in Europe where nature can still develop to a great extent without human influence. So that this can continue, the German coastal states declared it as National Parks: in 1985 the Schleswig- Holstein Wadden Sea, in 1986 Lower Saxony Wadden Sea and in 1990 the Hamburg Wadden Sea. The Wadden Sea in Schleswig-Holstein, Niedersachsen and the Netherlands was placed on the UNESCO World Heritage List in 2009.

Shennongjia Station is located in Xingshan County, Hubei Province, China. It is located in the southern slope of Mount Shennongjia. The altitude is 1290m above sea level. The typical forest types are the northern subtropical mixed evergreen and deciduous broadleaved forest. Shennongjia Station was established in 1994, it became a station of National Field Research Station network running by the Ministry of Science and Technology of the People’s Republic of China in 2005, and became a member of Chinese Ecosystem Research Network (CERN), CAS in 2008.

Akkeshi JaLTER site locate along the Pacific coast of Eastern Hokkaido. It consists of various habitats such as Bekanbeushi river system, Akkeshi-ko estuary and Akkeshi Bay, which formed an ecotone connecting freshwater, brackish water and marine environment.

UK Environmental Change Network (ECN) site. The Cairngorms site is located high in the Cairngorms, near Aviemore in Speyside, Scotland. The site lies on the North-Western flank of the Cairngorms encompassing the catchment of the Allt a' Mharcaidh (a site in the ECN freshwater network). It is part of the Invereshie and Inshriach National Nature Reserve, within the Cairngorms National Park, and covers some 10 km2. This is the first ECN site in the UK's sub-arctic zone and is an important link not only to other upland ECN sites but to alpine site in Europe and globally through the GLORIA network, and also to networks across the Arctic (SCANNET and INTERACT). The Cairngorms site has been used intensively for research since the 1970s. An Automatic Weather Station (AWS) has been operating at the site since 1984 and was used in the Surface Water Acidification Programme from 1984 to 1994. CEH and MI have used the site for long-term hydrological and snow studies for about 15 years. From 1997-1999 it was one of the ECOMONT (land use change in mountain areas of Europe) sites. Researchers at several universities and institutes use the site for vegetation, soils and nutrient cycling studies. The site forms part of the larger Feshie catchment in the NICHE programme (National Infrastructure for Catchment Hydrology Experiments). This site is nested within the Cairngorms National Park LTSER site (https://deims.org/1b94503d-285c-4028-a3db-bc78e31dea07).

The Bab forest (66 ha) was selected as an example of a lowland deciduous broad-leaved forest on loess for ecosystem research in the International Biological programme (IBP) in 1967. More than 60 researchers performed a comprehensive ecosystem research at the site within IBP and MaB programmes in 1967-1975. This period finished by production of syntheses in micro-meteorology and micro-climate, soils, soil microbiology, ecophysiological processes of plants (photosynthesis, water relations, mineral nutrition), primary productivity, nutrient cycles, water circulation, and secondary productivity. The ecosphisiological studies continued in 1975-1980, later the research was focused to plant population biology and alien plants invasions. The ecosystem research was re-established in 2007. The inventory of shrub and trees, herb vegetation, selected animal groups allowed identification of changes during 40 years caused probably by the climate changes and anthropogenic disturbances. The differences in decomposition of selected native and invasive plant species were assessed. The biomonitoring of the air pollution was done using mosses as indicator organisms. Now the research is focused to dynamics of forest ecosystem (vegetation, selected invertebrate groups, small mammals) and impact of forestry management (clear-cuts) to structure and dynamics of forest ecosystem. The multisite trampling experiment (ALTER-Net) and tea decomposition experiment (ILTER) were/are performed at the site.

A small watershed that collects floods and run-off. The lowest place is home to a (relativity) dense Acacia savana. The slopes are completely bare. The wadi is covered with alluvium resting on a 6 m layer of red surface of late Pleistocene, which includes silt, clay and fine sand. Rainfall is 30 mm
