Suserup Skov (19.2 ha) is an old growth temperate forest dominated by beech Fagus sylvatica, pedunculate oak Quercus robur, ash Fraxinus excelsior, wych elm Ulmus glabra, and black alder Alnus glutinosa, admixed with lime Tilia platyphyllos and sycamore maple Acer pseudoplatanus. KU/IGN-SNB, is a 19,2 ha old-growth beech-dominated mixed deciduous forests on western Zealand owned by Sorø Academy. The forest use dates back to 4200 BC. A conservation act was placed on the forest in 1925 for biological and recreational purposes but allowing a minimum odd felling until the act was updated in 1961 to a non-intervention forest. The forest is unique at European level in terms of nonintervention, and the long-term status as non-intervention forest has led to a unique steady state in biomass and accumulation of dead wood, thus serving as an important reference site for unmanaged temperate deciduous forest development. There are long-term data records of e.g. biomass, dead organic matter, soil, forest structure, flora and fungi starting from 1992. The platform is included in a series of paired managed and non-intervention forests for studies of forest structure, biodiversity and biogeochemistry in mature and old beech-dominated forests. Suserup Forest includes an ICP Forests level II plot (2001-). Upgrades: eLTER master sites: soil moisture content (TDR), remote sensing of growth and forest structure, LAI, NDVI (Lidar, camera), continuous plant phenology (web cam),and insect monitoring (optical sensors) as biodiversity measures, ambient air quality and air pollution.

insect (Diptera, Chloropidae) data of grasslands of coastal reserve Randu Meadows. Latvia. Insects were collected on 5 transects (26 m) along coast line perpendicular to the coast.From 1996-2012 three times per year monthly (June, July, August) insects were collected by entomological sweep net method along each transect (50 sweeps). Seasonal data were obtained by pooling monthly data for each transect.

The LTER site is a COMPLEX site, with observation sites focusing (a) on the three glaciers in the Kaunertal Valley, (b) 10 ecological and erosion sites along a succession gradient in the pro glacial, and (c) one climate station. The station (a) is run by Andrea Fischer (AAS), stations (b) and (c) within the PHUSICOS project coordinated by Sabine Kraushaar (University of Vienna). In the proglacial area of the Gepatschferner glacier ten mechanical erosion sites with each three plots (each 2x3m, see picture) are installed monitoring biotic and abiotic interrelations in 5 different succession classes. Small scale erosion processes such as splash, rill and interill erosion processes are quantified as a function of the present species composition. A climate station on 2350m run by solar power complement the set up.

Counting of resident and wintering Greyleg Geese (Anser anser) and tagging them with neck collars and GPS locators. Furthermore counting of hatched juveniles in early summer. Everything synchronized with the colleagues of the Hungarian side of the Nationalpark.

The Durme debouchment is a subsite (12 ha) of the Scheldt Estuary and its alluvial plains. The setup for deployed in the context of eLTER_RI is a cross-shore open-air laboratory open for other researchers and students to experiment in a long-term in-situ setup. The responses studied are on the level of sediment, infauna of tidal flats, (ground)water levels, carbon (including microphytobenthos and green-house gases), (ground)water quality and marsh vegetation (plant biodiversity, biomass). An end-goal is to provide long term field data to develop numerical eco-morphodynamic model(s) that is/are able to predict the effect of changed water budgets on carbon sequestration or greenhouse gas emissions, biodiversity (by eDNA), macro-invertebrate production and changes in tidal wetland plant species distribution and production in a cross-shore approach.

The Mullwitzkees is located in the Venediger Group in the core zone of the National Park Hohe Tauern. The upper part of the glacier (outer Mullwitzkees) is oriented to the south.The lower part of the glacier, especially the tongue, is oriented to West-South-West.

Landslides (translational and rotational slides, debris flows, rock avalanches, rock falls, etc.) rank among the most common natural hazards in Lower Austria. As these processes often inherit sporadic phases of activity, it is essential to generate specific long-term measurement series, enabling the analysis of surface and sub-surface dynamics in connection with potential triggering factors. Therefore, in 2014 the project “NoeSLIDE – Monitoring diverse types of landslides in Lower Austria” was initiated. Three subsites are summarized under the parent site "LTER NoeSLIDE".where various types of landslide processes, Hofermühle (complex earth slide - earth flow), Gresten (Salcher landslide) and Brandstatt are monitored with "classic" as well as novel approaches. This includes surface and subsurface monitoring systems. The main research aims comprise implementation of long-term monitoring systems (10+ years) for continuous observation of gravitational mass movements, testing of novel and innovative methods on multiple locations and data availability in a WebGIS application for simple online analyses for authorized users.

The dataset provides information about the soil chemical properties at eight permanent LTER sites (named site 1, 2, 3, 6, 7, 8, 9, and 10, according to the LTER site numerations), located between 2686 (site 10) and 2854 m a.s.l. (site 6). The investigated period is 2016-2020. Details: Site 1 (coordinates: 45°52'22.43"N, 7°52'25.84"E; elevation: 2840 m a.s.l.), Site 2 (coordinates: 45°52'22.17"N, 7°52'38.07"E; elevation: 2800 m a.s.l.), Site 3 (coordinates: 45°52'13.52"N, 7°52'35.01"E; elevation: 2770 m a.s.l.), Site 6 (coordinates: 45°52'32.21"N, 7°52'31.87"E; elevation: 2854 m a.s.l.), Site 7 (coordinates: 45°52'29.13"N, 7°52'44.71"E; elevation: 2813 m a.s.l.), Site 8 (coordinates: 45°52'27.74"N, 7°52'56.86"E; elevation: 2749 m a.s.l.), Site 9 (coordinates: 45°52'23.80"N, 7°53'3.96"E; elevation: 2720 m a.s.l.), and Site 10 (coordinates: 45°52'21.76"N, 7°53'9.32"E; elevation: 2686 m a.s.l.). The bedrock is primarily micaschists, with some inclusions of amphibolites and calcschists. The vegetation of the sites is included in the ‘Siliceous alpine and boreal grasslands’ (habitat 6150, according to the EU Habitat Directive). At each site, consisting of paired plots for soil and vegetation survey, three 9 m2 plots are established, where three topsoil samples (A horizon, 0–10 cm depth) are collected each month during the snow-free season. On soil samples the following analysis are performed: N-NH4, N-NO3, dissolved organic carbon (DOC), total dissolved nitrogen (TDN), dissolved organic nitrogen (DON), microbial carbon (Cmicr), and microbial nitrogen (Nmicr).

The dataset provides information about the physical and chemical characteristics of the snowpack. Every year, a snow profile is open and sampled before the beginning of the melting season, close to the Istituto Scientifico Angelo Mosso (45°52'31.27"N, 7°52'17.09"E, elevation: 2900 m a.s.l.). Data are available for the years 2009 and 2010, and the period 2014-2020 (2016 was not analysed). Snow depth and density are measured, and snow water equivalent (SWE) is calculated. The analysed snow chemical parameters are: pH, electrical conductivity (EC), N-NH4, and N-NO3 (period 2009, 2010, 2014-2020); dissolved organic carbon (DOC), total dissolved nitrogen (TDN), and dissolved organic nitrogen (DON) (period 2014-2020); cations (Ca, Mg, Na, K) (years 2009, 2010, 2015); anions (S-SO4, N-NO2, P-PO4, Cl) (years 2009, 2010, 2015); trace elements (Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Rb, Si, Ti, V, Zn) (year 2015).
