In Doñana official groundwater level and recharge monitoring is done by the Guadalquivir Water Authority (Confederacion Hidrografica del Guadalquivir CHG). Levels are recorded monthly at 195 measurement points distributed throughout the whole area (unsaturated zone) with starting dates between 1974 and 1994. Additional measurements related with groundwater recharge and chemical composition, covering different periods and areas, are made by research entities. Geological and Mining Institute of Spain (IGME) installed soil moisture sensors and piezometers in the sandy soils of Doñana in 2008 and one lysimeter has been installed in 2016

The Environmental Research Observatory Site of Fontaine de Vaucluse – LSBB is an observation and experimental site located in south-eastern France. Observation and experimentations are performed by UMR EMMAH (AU/INRAE) at two different scales: at catchment scale since 1981 (these observations and experiments are reported within the SNO KARST) and at micro-site scale since 2002 at the Low Noise Underground Laboratory (these measurements are reported within the SNO H+ network). Fontaine de Vaucluse is both outstanding and typical of the mediterranean context. This spring is one of the largest springs in Europe with an average discharge over 20 m3/s. It is the main outlet of a large limestone catchment (~ 1160 km2), that extends mainly over natural land, with thick unsaturated zone (800 m in average).

Located 2 km east of the Science Campus of the University of Poitiers, the Hydrogeological Experimental Site (HES) occupies an area of 12 hectares on land belonging to the University. From the geologic viewpoint the SEH occupies the north flank of the “Seuil du Poitou”, a huge Mesozoic carbonate plateau marking the transition between the Aquitaine and Paris sedimentary basins. The studies conducted at the SEH focus mainly on the Dogger Aquifer. The experimental layout now comprises 35 boreholes, including two vertical and two inclined cored holes.

Located in South West of Brittany, western France, the elementary catchments of Kerbernez are underlain by old bedrock and is characterised by a oceanic, humid and temperate climate and by an intensive agriculture. In every catchment, the hydrology is controlled by a shallow aquifer made of the unconsolidated weathered bedrock. The water table in the aquifer is close to the soil surface in bottom land areas of catchment. During storm event, surface runoff occurs mainly over the saturated soils of bottom lands. The Environmental Research Observatory (ERO) AgrHyS focuses on the response times of changing Agro-Hydro-Systems (defined as a catchment influenced by agricultural activity) for hydro-chemical fluxes.

The Oueme mesoscale site (Benin) is part of the AMMA-CATCH observation network. Its characteristics are as follows a 14000 km² basin in sudanian climate on a crystaline basement. The studies focus on the hydrological cycle, the water budget and the hydrological processes.

The Calperum Mallee SuperSite is a member of the Australian SuperSite Network (SuperSites, http://www.supersites.net.au/), a facility within the Australian Terrestrial Ecosystem Network (TERN, http://www.tern.org.au/). The SuperSite is located on Calperum Station, near Renmark, South Australia with research plots located in mallee woodland, Callitris woodland and floodplain black box, river red gum and lignum ecosystems. The property was a pastoral grazing lease for nearly 150 years, so it has suffered grazing-induced modifications to its ecosystems that are now being actively restored. The Native Title for the area is held by the First Peoples of the River Murray and Mallee. Key research objectives include: • What are the fundamental energy, carbon, water and nutrient stocks and flows in the Mallee, Callitris woodland and river floodplain ecosystems? • How are these stocks and flows responding to the management interventions (reduced and controlled grazing, controlled fire, controlled floods on the floodplain)? • How are the biota changing in form, frequency and distribution as climate changes and management interventions are imposed? • How important is the connectivity between these ecosystems for hydrology, faunal movement and as refugia in times of drought?

MEDYCYSS observatory (Hérault, France) is a mediterranean karstic hydrosystem, located between Hérault and Vidourle rivers with a 1200 km2 area. The territory consists of several sites of observation and experimentation with three hydrographic networks in interaction with the karst system: the Lez, the Mosson and the Coulazou.

FNQ Rainforest SuperSite-Daintree is a member of the Australian SuperSite Network (SuperSites, http://www.supersites.net.au/), a facility within the Australian Terrestrial Ecosystem Network (TERN, http://www.tern.org.au/). SuperSites aims to answer both network wide and site-specific science questions through long term monitoring using both sensor technology and classical field methods. The FNQ Rainforest SuperSite is divided structurally into two transects, each based around an intensive study site node: the lowland rainforest node is based in the Daintree rainforest near Cape Tribulation and the upland rainforest is based at Robson Creek. The rainforests of FNQ occupy less than 0.2% of Australia’s landmass, yet support more than 10% of its flora, 36% of its mammals and 48% of its birds. The last remnants of the rainforests which formerly covered most of the continent, these globally significant World Heritage communities are also a repository for many ancestral lineages of the iconic species of Australia today, including kangaroos and eucalypts. Significant environmental clines (altitude, temperature, rainfall) exist over short distances in the region. This enables the monitoring of multiple parameters across a broad range of environments possible within the compact footprint of the FNQ Rainforest SuperSite. The Daintree node comprises two sites (i) the Daintree Rainforest Observatory (DRO) at Cape Tribulation, comprising a long-term monitoring plots, canopy crane, and extensive researcher and teaching infrastructure and (ii) research facilities at the Daintree Discovery Centre at Cow Bay, an award winning ecotourism interpretive centre featuring a canopy tower, aerial walkway and scientific monitoring. Key research objectives include: ● How are the biota (in particular locally endemic species) changing in form, frequency and distribution and what are the drivers for this? ● Does the vegetation represent a stable structure (overstorey versus understory dynamics) or has climate change affected it? ● Which taxa of organisms are the most sensitive to local climate change and how can these be assembled into an accurate biodiversity monitoring tool? ● What are the fundamental vertical and lateral energy, carbon, water and nutrient stocks and flows in the tropical forests of north Queensland? ● How are these stocks and flows responding to past management and climate change and how are they likely to respond in the future? ● How important is the connectivity between these ecosystems
