This research site develops long-term ecological studies in experimental units located in Protected Areas along the altitudinal gradient of Atlantic Forest types: Low Altitude Ombrophilous Dense Forest (5 to 50 m above sea level), Submontana Ombrophilous Dense Forest (50 to 500 m above sea level), and Montane Ombrophilous Dense Forest (500 to 1.200 m above sea level). In each altitude, all trees with a DBH ≥ 5,0 cm that fall inside 4 independent 1 hectare permanent plots, divided into a grid of 10 x 10 meter parcels, are being considered. The site extends from 23°15' S a 23° 40 S to 44° 40’ a 45° 40’ W. within areas of the Nucleus Caraguatatuba, Cunha, Picinguaba and Santa Virginia from the Serra do Mar State Park/PESM. The database on composition and structure of the forest will allow a choice of species for more detailed studies on reproduction biology; seed anatomy and reserves; germination; photosynthesis and water use efficiency; nitrogen assimilation, transport and metabolism; plant populations structure and dynamics; techniques; genetic structure of plant populations using molecular markers; determination of forest age by DBH classes and using 14C; determination of annual average growth rates of key species; and phenology. Multivariate analyses has been used to check for functional groups, or groups of species that share a common behavior and ecology. The comparison of different groups along the altitudinal gradient will allow investigation of the effect of altitude in the functioning of these groups. Simultaneously, the inputs of nitrogen through precipitation, biological fixation, and soil mineralization and nitrification are being determined, along with key parameters of N losses through denitrification and export by streams, allowing a preliminary nitrogen mass balance along the altitudinal gradient. Water and carbon balance of the forest will be estimated along with the seasonal variation of this balance through use of micrometeorological towers and Eddy-covariance technique. The photosynthesis/respiration balance of the ecosystem will be used to determine the role of the forest as a sink or source of carbon to the atmosphere. Our final goal is to integrate the results of all activities listed above, scaling-up from individual trees, to families, to functional groups, and finally to phytophysiognomies, allowing us to investigate in detail the structure and the functioning of the forest.

The Negev Highlands (NH) LTSER platform is situated between the Sinai Peninsula to the west and the Arava – Dead Sea depression to the east. This is a rocky terrain, covering an area of 17,000 sq. km with series of ridges at an altitude of 400-1000 m above sea level. As part of the Saharo-Arabian desert belt, the climate across the NH is arid to hyper-arid region: January’s mean daily temperature is 10 °C and July’s mean daily temperature is 25 °C The potential evaporation is approximately 2200 mm/y, and mean annual precipitation is 70–130 mm, with large inter annual variations. The rainy season occurs during the winter months, from November to March. The area is rich with unique natural landscapes. One of the most prominent of these are the Makhteshim, which is the largest erosion craters in the world. In addition to its unique landscapes, it is also a habitat for various species of flora and fauna that are adapted to arid zones and highlands, some of which are endemic to the area. The Negev Highland LTSER platform includes two LTER sites: Avdat Site in the arid zone and Makhtesh Ramon site in the hyper arid zone. Archaeological remains indicate that humans lived in the area for at least 1.4 million years. Today, about 10,000 residents live here, in towns, agricultural communities, small Bedouin tribal villages and tourist-agricultural farms. Most of it is concentrated along the main route (Route No. 40), while much of the area beyond the roads is either designated nature reserves or firing zones. The two main livelihoods in NH today are agriculture - mainly vines and olives, and tourism; Both are greatly affected by climate change. Agriculture relies on desalinated seawater imported into the area. However, it is affected by the climate in several ways: 1) flash floods cause increased soil erosion. 2) Long periods of drought during the winter, cause increased evaporation and therefore large water consumption. This is when the price of water is the main expense of the farmers, and increasing it may make agriculture unprofitable. 3) The uncertainty regarding the amount of precipitation and their timing, characterizes the arid environment. Recent climate changes are increasing this uncertainty and therefore make it very difficult for farmers to plan their land cultivation and expenses. Climatic uncertainty poses a significant challenge also for tourism operators; Jews and Bedouins, as well. This is due to the multiplicity of events of extreme climatic conditions (extreme cold or extreme heat), which repel tourists from reaching the area. And, a multitude of years when there is not enough precipitation to generate the famous spring bloom of the area. For the past 7 years, the NH LTSER's researchers have been working closely with three stakeholder groups in the area: winegrowers in the valleys, the Negev Highlands Tourism Association and Bedouin tourism operators. In Green Transformation we will actively engage with this group, through tow case studies: 1) The Desert Miracle farm - which will serve as a monitoring and dissemination knowledge farm; In a collaboration with the owner of the farm, R and D agriculture in the NH and the Center for Flood Research (DSASC). 2) Tourism in the NH; In collaboration with the NH Tourism Association. Through joint work with these NGOs, we will develop a long-term monitoring program and educational materials. The topics we will deal with: reducing soil erosion and increasing soil moisture, by using appropriate agricultural methods to multiply flash floods, which will be distributed to additional farmers in the area through activities at the monitoring farm. and to tourists through workshops of the Tourism Association. In the case of tourists, the aspect to be monitored is the number of tourists who come to the area in relation to the weather conditions. Together with the Tourist Association we will develop tourist-monitoring system. The high sensitivity of the arid region to climate change and the great exposure of the impact of these changes on animals, plants and humans, invite possible tourist-educational activities aimed at transformation in ways of thinking and behaving. An environmental education program and educational tools will be developed together with the Tourist Association. Their impact will be monitored in collaboration between the NH LTSER platforms researchers and tourism operators.

Kuršių nerija, the Curonian Spit, is a narrow strip of sand stretching 98 kilometres along the Baltic Sea in western Lithuania. The Curonian Spit is a unique and vulnerable, sandy and wooded cultural landscape on a coastal spit which features small Curonian lagoon settlements. The Spit was formed by the sea, wind and human activity and continues to be shaped by them. Rich with an abundance of unique natural and cultural features, it has retained its social and cultural importance. Local communities adapted to the changes in the natural environment in order to survive. This interaction between humans and nature shaped the Curonian Spit cultural landscape. The history of the Curonian Spit is dramatic: 5,000 years ago, a narrow peninsula (98 km in length and 0.4-3.8 km in width), the Great Dune Ridge separating the Baltic Sea from the Curonian Lagoon, was formed on moraine islands from sand transported by currents, and later covered by forest. After intensive logging in the 17th and 18th centuries, the dunes began moving towards the Curonian Lagoon, burying the oldest settlements. At the turn of the 19th century, it became evident that human habitation would no longer be possible in the area without immediate action. Dune stabilisation work began, and has continued ever since. By the end of the 19th century, a protective dune ridge was formed along the seashore to prevent inland sand migration, and the Great Dune Ridge was reinforced using trees and brushwood hedges. Currently, forests and sands dominate the Curonian Spit. Urbanised areas (eight small settlements) cover just about 6% of the land. One part of the 50 kilometres long Curonian Spit belongs to the Republic of Lithuania. The other to the Russian Federation. With its still drifting sand dunes, the sea side forests cherishing the hundred-years-old pine trees, dunes covered by a mountain pines’ carpet planted by hand, white sand beaches and the old fishermen villages.

LTER site Oberes Stubachtal is a long-range research site with a main focus on the measurement of the annual mass balance of the Stubacher Sonnblickkees (SSK) and processes of different glaciers, going along with water budget estimations within the catchment area of the dam lakes Weißsee and Tauernmoos that are controlled by the Austrian Federal Railways (ÖBB) and can gives you more Information about the catchment hydrology. Regular observations and systematic studies had begun with measuring the glacial length in 1960 by the brothers Heinz and Werner Slupetzky. The Massbalance of SSK is measured since 1963 and indirect back calculated till 1946. The Glaciers are photogrammetric mapped since 1963. Additionally the lake “Unterer Eisbodensee”, originated in the 1980s, is monitored with temperature, waterlevel and runoff by the Hydrographical Service of Salzburg since 2006. In the center of this researchsite is the meteorological station Rudolfshütte operated by the ZAMG since 1962. The Rudolfshütte is also a Mountain Hotel and can be use as a Basecamp. Since the year 2004 there are some TLS measurement for the generation of high resolution DTMs of the end of the glacier tongue and glacier forefield of the Odenwinkelkees and of the sourounding area of the lake “Oberer Eisbodensee”.

In the Rofental (Ötztal Alps) a consortium of the three institutions, and open to research partners worldwide, concentrates on studying and monitoring cryospheric, atmospheric and hydrological processes and changes with particular attention to the complex topography and climate settings of the Alpine terrain. First documents from glaciers in the Rofental, Ötztal Alps, date back as far as 1601 and regular observations and systematic studies had begun more than 150 years ago. First geodetic maps where generated in the late 19th century, first rain gauges were mounted in 1929 and glacier mass balance time series of Hintereis-, Vernagt- and Kesselwandferner are among the longest uninterrupted world-wide, building a basis for regional hydrological studies, for glacier-climate and ice dynamic research, and for estimating the world wide glacier’s contribution to sea level rise. By 2014, networks of stakes and pits for mass balance monitoring are maintained at Hochjoch-, Hintereis-, Kesselwand- and Vernagtferner by the consortium members. Runoff gauges at Vernagtferner and in Vent (operated by the Hydrological Office of Tyrol) and a network of rain gauges in the Rofental basin are the basis for high mountain hydrological studies. A varying number of automatic weather stations on and in the surroundings of the glaciers are operated by the Rofental consortium. The glaciers in the Rofental are frequently used as a test site for process studies, model development and evaluations and for new remote sensing or ground based methods in glaciological research. A series of airborne LIDAR derived high resolution DTMs of Hintereisferner and its surroundings are available since 2001. They are subject of ongoing evaluations and method comparison studies as well as for monitoring and studying periglacial morphodynamics. The generated data are available from the consortium partners, glaciological key results are annually reported to the World Glacier Monitoring Service (WGMS). A research station on Hintereisferner (with observer status in the Horizon 2020 INTERACT network) and one at Vernagtbach serve as logistic bases for fieldwork. In recent studies, socio-ecological research aspects – e.g. in relation with the use of water for energy production and tourism – comprise the natural scientific investigations.
