Kok Ma water research station in located at Doi Suthep-Pui National Park about 20 km from Chiang Mai city. The station was established in 1965 by Kasetsart University and University of Hawaii. The altitude of this station ranges between 1,300-1,600 m above mean sea level. The dominant vegetation is hill evergreen forest.

The SERS is situated in the Korat Plateau between latitude 14°25′-14°33′ N and longitude 100°48′-100°56′ E (Fig. 1). The SERS covers an area of approximately 82 km2 (Trisurat et al. 2006) in seven sub-districts of Nakhon Ratchasima Province in northeast Thailand, namely Ta Khob, Lam Nang Kaew, Phu Luang, Udomsap, Wang Mee and Wang Ngam Khiew. Its altitude ranges from 250-762 m above mean sea level and approximately 35% of the research station is situated in altitudes between 300-400 m. The SERS is surrounded by extensive agricultural areas and human settlements. Based on visual image interpretation of Landsat-TM images, nine land-use/land-cover classes were classified, namely, dry evergreen forest, mixed deciduous forest, dry dipterocarp forest, secondary growth, plantation, grassland, old clearing, agriculture & settlement, and water body.

Beijing Urban Ecosystem Research Station is located in Beijing. Urban ecosystem is a complex social-economic-ecological system dominated by human beings. Urban ecological elements, including climate, atmosphere, hydrology, soil, organisms, etc, and ecological process such as material flow, energy flow, etc, are products of interaction between human activity and natural environment. These will evolve with variation of the human-nature relation as well. Beijing is the center of policy, economy, culture, science and technology in China and it is also an international metropolis. Beijing covers 16,400 km2 (built area is 1204 km2) with population of more than 15, 810,000 in 2006. Beijing urban ecosystem research station was based on State Key Laboratory of Urban and regional Ecology, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences and started constructing in 2001, consisting of monitoring net, indoor specimen analysis and conservation room, information data management and analysis room and official documentation room. Up till now, laboratories concerning air, water, soil and microorganism have been set up engaging in research of Beijing urban ecosystem’s structure, typical process and function.

UK ECN site. The shallower regions of Lower Lough Erne (109.5 km2), present an example of a flooded drumlin landscape which has created an intricate mosaic of land and water. As a consequence of differences in depth and area, the water retention time of the Lower Lough is four months. The phytoplankton abundance in the deep open water of the Lower Lough is more typical of a mesotrophic water body despite comparatively high phosphorus concentrations (58 mg P l-1, 2017). The paucity of phytoplankton in this region is attributed to a high back-ground light attenuation from the peat-stained water and the greater depth of the mixed water zone (>35 m). The lake supports a fish population dominated by the introduced roach, as well as pike, perch, bream, trout and pollan. The Zebra Mussel is a relatively recent introduction (1996) which has impacted significantly on the lake ecology. Water monitoring is undertaken at the deepest portion of Lower Lough Erne.

Reserva de la Biósfera Chamela-Cuixmala dominada por bosque tropical seco en la Costa del Pacífico Mexicano en el estado de Jalisco. El relieve predominante en Chamela consiste de lomeríos bajos y con fuerte pendiente sobre rocas volcánicas del Terciario en las que predominan la riolita, el granito y la granodiorita. Los suelos de Chamela son relativamente jóvenes y someros e identificados como Entisoles. La geología y topografía de la región de Chamela pertenece a la provincia fisiográfica de la Sierra Madre del Sur.

Vascular plant cover estimated in the Kiskunság Restoration Experiments (1995-2019). The Kiskun Restoration Eperiments are located in abandoned arable land and clear-cut tree plantations mostly, but not entirely within LTER Fulophaza and close to the Bugac-Bocsa-Orgovany Site in the Kiskunság Sand Ridge. We have three restoration experiments with long-term monitoring of changes in plant species cover according to treatments. The locations are differentiated as stations in the database. Experiment one (Exp1) involved mowing as treatment (1995-2001) on clear-cut and chemically treated previous Robinia pseudo-acacia plantations in Fülöpháza, Izsák and Bugac (three stations). A 30 m x 40 m block was allocated for the mowing treatment at each site with twelve adjacent plots of 10 m by 10 m, with six control (unmowed) and six treatment (mowed) plots randomly selected. We also had some reference grassland plots. Monitoring took place in three permanent 2 m x 2 m units per each site (n=18/treatment) from 1995-1999, re-sampled several times until 2017. Data are accessible separately for the three sites (stations), sample ID reflects the 2 m x 2 m sampling units. Experiment two (Exp2) is located in Fülöpháza in on abandoned farmland (station). The experiment involved old-field sites. Treatment was carbon addition to induce soil N immobilization in 1998-2003. The block design was the same as above. Monitoring took place from 1998-2004, plus re-sampled less frequently till 2018. Data are accessible in one file for the station, sample ID reflects the 2 m x 2 m sampling units. Experiment three (Exp3) is also located in Fülöpháza in abandoned fields. Three stations are included that are abandoned arable fields of different age. Restorative treatments involved seeding, mowing and carbon amendment in 1 m x 1 m units (n=64) from 2003 to 2008. Monitoring took place in 2003-2008, resampled in 2019. Data are accessible separately for the three sites (stations), sample ID reflects the 1 m x 1 m sampling units with indication of treatments.

Dataset provides Total Nitrogen (TN in mg L-1) in Lake Paione Superiore (LPS) at different layer depths measured at least twice per year (late summer/autumn) during the period 2014-2020. In total 37 records of Total Nitrogen recorded in the Lake are uploaded.

The site is located in the Eastern Carpathians (Romania). The predominant ecosystems are grasslands located above tree line, dominated by Carex curvula, Juncus trifidus (alpine zone) and Nardus stricta, Festuca airoides (subalpine zone). The site consists of monitoring points in subalpine and alpine meadows across the whole range of the Rodna Mountains.

The site is a managed realignement (Sea Wall Removal) combined with a land lowering to start estuarine development in a suitable tidal frame. The site was created in 2002 and monitored in an initial phase intensively. (aspects of morphology, sediment characteristics (including polluents), macrozoobenthos, vegetation and birds). Vegetation and birds are ongoing monitoring.
