Lesvos is a geological mosaic assembling from limestones a.o. metamorphic rocks and soils to volcanic and serpentine ones. It is characterized by three climatic profiles (semi-arid, arid–sub-humid, and a transitional one). Considering its size (1,634 km2), the island is rich in habitat types extended from thermo-Mediterranean (phrygana, scrub, pine forests), meso-Mediterranean (evergreen to semi-evergreen oak forests), through to supra-Mediterranean (deciduous oak and chestnut forests), even up to montane-Mediterranean zone (black pine forests). Furthermore, the island encompasses interesting man-made systems, such as agro-ecosystems (olive groves, cultivated & abandoned fields), terraced landscapes, graze lands, salt-works, not to forget its numerous wetlands.

Samaria (White Mountains) National Park is located on the West part of island of Crete and was declared as a National Park via a Royal Decree in 1962. It is a muli-designated area and specifically a National Park, Landscape of Outstanding Beauty, Natura 2000 site coded GR 4340008 and GR4340014 and Biosphere Reserve in the framework of the “Man and Biosphere” Programme of UNESCO. It has been awarded with the European Diploma of Protected Areas of the Council of Europe. Also a hotspot for biodiversity and a place with a strong and important anthropogenic environment (history, special songs, traditions, etc.). It contains one of the largest gorges in the Balkans, Samaria Gorge, with a total length of 13 km while nine main gorges are located within the area of the White Mountains. These specific landscape configuration schemes sustain unique abiotic and biotic environmental characteristics, most of them unknown, because of the site’s wilderness and difficultness for direct scientific filed work. The specificity of the area can be easily identified in numbers: 58.454 ha, altitude ranging from 0-2.454m, more than 50 summits higher than 2000 meters a.s.l., 14 different types of habitats, approximately 40% of the entire extent of the county of Chania. Mean Annual Rainfall is between 600mm to 2000mm depending on the elevation. The entire area comprises one of the two main environmental lungs of Crete and a configuration leading to the current meteorological and hydrological conditions set in the western part of the island. President of the National Park is Dr. Petros Lymperakis, researcher from the Natural History Museum of Crete (lyberis@nhmc.uoc.gr). The National Park is characterized by a rich biodiversity, a high degree of endemism in fauna and flora, distinctive geological configurations and specific landscape features. Distinctive species of fauna found in the area are: the Cretan wild goat (Capra aegagrus cretica), the largest mammal of the island, the Cretan wildcat (Felis sylvestris cretensis) and a species of mouse (Acomys minous) which is considered to be rare. The rich avifauna of the area includes 69 species, with Gypaetus barbatus among others. The area houses 172 endemic species and subspecies, while 97 of them are endemic to Crete and 24 are specifically endemic (steno-endemic) to smaller areas. Some of the most distinctive species are: Cephalanthera cucullata, Nepeta sphaciotica, Bupleurum kakiskalae and Zelkova abelicea. The past 2 years a complete survey has begun in order to identify the Park’s central environmental characteristics. Nowadays, the monitoring system is comprised by: 1) Monitoring and surveillance of 15 terrestrial habitats and 34 species of flora. 2) Monitoring and surveillance of 256 species of avifauna. 3) Monitoring and surveillance of all possible species of fauna, including coastal and marine species. 4) Monitoring and surveillance of two marine habitats. 5) Recording of meteorological and hydrological conditions via four (4) meteo-stations located in the vicinity of the National Park and transmittance of data through the internet. The basic threats and pressures characterizing the site can be cumulated in: Α) Landscape fragmentation Β) Desertification induced by overgrazing and uncontrolled fires C) Modifications in water and groundwater regime induced by large scale infrastructures D) Poaching and uncontrolled abstraction of endemic species of flora E) Massive touristic flow and F) Relative medium and large-scale touristic infrastructures.

Tierberg Karoo Research Station (TKRS) is a Long Term Ecological Research field facility available for use by organisations involved in research and tertiary education in the natural sciences. The field site comprises 100 ha of natural Karoo shrubland situated in the Karoo Biome. The field site has been fenced to exclude domestic livestock since July 1987. Studies of plant, bird and small mammal populations at this site have contributed substantially to present conceptual understanding of ecological process in the Karoo and provide valuable baselines for research.

The sites Friedeburg, Greifenhagen, Harsleben, Schafstädt, Siptenfelde and Wanzleben are part of the TERENO Harz / Central German Lowland Observatory in Saxony-Anhalt run by the Helmholtz Centre for Environmental Research UFZ. These sites have a focus on biodiversity monitoring in the “normal landscape” which is characterized by agricultural use (about 60 % coverage of Saxony-Anhalt). Each site is a 4x4 km landscape of mainly arable land and semi-natural habitats like e.g. hedges and forests. The site Siptenfelde is in the eastern part of the Harz mountains and characterized by a distinct topography. The mean elevation is 423 m asl and besides meadows and agricultural fields the village Siptenfelde is surrounded by forest. Thus the area covered by forest amounts to 61 %, crop fields 18 % and all semi-natural habitats sum up to 15 %.

LTSER Trnava is located in the south-west Slovakia, in territory of one city (Trnava) and 44 rural municipalities with total area of 741.33 km2. Arable land dominate (65.13 %), followed by forests (17,78%), built-up area 7.84%, grassland (2.15%), gardens (1.83%), water bodies (1,38%), vineyards (0,81%), orchards (0.2%), and other plots (2.9%). The main part of the LTSER (central and southern parts) is located in the Danubian Lowland. Because of the best, most fertile soils and favourable climatic condition, it is intensively used for agriculture, especially as arable land. In this part of LTSER is located the largest settlement – Trnava. It represents the administrative centre of the county and region with highest population, trade and industry. Hilly northwest part of the LTSER, located in the Little Carpathians Mts. belongs to the Malé Karpaty Protected Landscape Area. This is the only large protected area having vineyard character in Slovakia; vineyards forms transition belt between lowland arable land and forested hills/mountains. Several types of deciduous forests are developed – oak-hornbeam and beech forests are most common, in steeper sites are developed ravine forest dominated by ash and maple. The LTSER represents intensively used industrial and agricultural area with specific environmental problems (strong degree of contamination of environment, the degradation processes of agricultural land, etc.) and low degree of ecological stability. Use of the most productive soils for construction of industrial parks represents a significant environmental issue.

Saldur Catchment covers an area of app. 100 km2 and includes different elevations, topographic aspects and ecosystems (meadows, pastures, forests and glacier forefields).Measurements started in 2010. In total there are 17 weather stations distributed throughout various ecosystem types (cultivated meadows, pastureland, forest, glacier forefield), which enables analyses at a plot level up to a complete landscape level. Measurements are primarily used to validate hydrological models and to model various ecosystem services such as productivity, water availability and protection against natural hazards. This site is also equipped with five units to measure sap flow in the stem and an automatic dendrometer; the data are used to investigate the influence of climate factors on common coniferous trees in the area.
