The restoration sites are located in abandoned arable land and clear-cut tree plantations mostly, but not entirely within LTER Fulophaza that is a high diversity site, both in terms of habitats and species, in the Kiskunság Sand Ridge. It uses some of the central facilities of the KISKUN LTER, such as the meteorological station and the field research station with accommodation opportunities, and a couple of long term monitoring sites and field experiments.

Mars, Mont Mars, (Fontainemore, Aosta)

More than half is covered by plantations of Cryptomeria japonica and Chamaecyparis obtusa. In natural forest areas, Abies firma and Tsuga sieboldii are dominant. In the deciduous broad-leaved forests located over 950m above see level, Fagus crenata is observed.

Marine Research Station “Zmiinyi Island” (ZMN) of the Odessa National I. I. Mechnikov University (ONU) is located on the Zmiinyi Island (45°15'22.0" N and 30°12'03.8" E) in the north western Black Sea (NWBS) about 35-40 km far from the Danube Delta.

Hydrometeorological and biogeochemical observations within 5 embedded catchments (from 0.2 to 14.5 km2). Alpine Mediterranean climate with heavy rainfall and flash floods in automn. The geology is mainly granite. The land use is mainly grassland and forest. More information at http://www.ohmcv.fr

Aquitain's karsts observatory (Aquitaine, France) regroups different karst sites located on the edge of the Aquitain sedimentary basin. These karst watersheds range from 0.01 km² (Lascaux cave) and 1 km² (Cussac cave) up to 100 km² (Toulon springs) and the land use consists of forests and agriculture under modified oceanic climate. This observatory consists of various observation and experimentation sites like patrimonial caves and large karstic hydrosystem outlets.

The site is divided into two different types of environments: 1. Coastal marine environments. Marine coastal areas of Sardinia, in particular, the Gulf of Asinara in the north and the Gulf of Olbia in the north-east, affected by different types and intensities of human impact and by the resulting presence of different environmental conditions from the point of view of water quality. 2. Lagoons and coastal ponds. Lagoons and coastal ponds located along the west-central coast of Sardinia, in the Gulf of Oristano. These sites are all important wetlands included in the Ramsar Convention, are IBA (Important Birds Area) and SIC and ZPS. The ownership of the sites is the Regional Government of Sardinia. Fisheries and aquaculture are generally the most important human activities, and there are also educational and recreational activities. They are affected by various environmental issues, mostly related to the process eutrophic.

Measurements of lake chemistry are part of lake monitoring, which is usually carried out by monthly sampling at many regular lake sites (5 to 17 sites depending on the intensity of the measurements over the years). The integrated sample represents the whole water column of this polymictic shallow lake with a mean lake depth of 1.2m. The measurement satisfy the analytical standards of Ö-Norm in Austria.

Plynlimon is at the headwaters of the Rivers Severn and Wye. The infrastructure at Plynlimon consists of 10 instrumented research catchments representing different land use options on the same geological parent material. It is the UK’s Critical Zone Observatory, part of the EU and global network of CZOs and is an ExpeER site. The infrastructure records high temporal resolution river flow and meteorological data (40 year data record) and stream water and precipitation chemistry for cations, anions, trace metals, nutrients, pH and alkalinity (30 year data record) and some data for suspended sediment. The site has an extensive spatial data library including topography, digital terrain model (DTM), soils, geology and vegetation/land-use available, open access, through the Environmental Information Data Centre (https://catalogue.ceh.ac.uk/documents/91961a0f-3158-4d00-984d-91eb1e03e8bd). Sub sites in the catchments represent a range of upland management types: mature/clear cut/replanted conifer forest; acid grassland; eroding peatland; improved grassland.Samples analysed for a wide range of major, minor and trace components. Bulk precipitation and cloudwater chemistry is also measured at one location.
