The site consists of “orographic islands” with high elevation vegetation in central Mediterranean basin, along the Apennines mountain range, within the Appennino Tosco-Emiliano National park and partially in the Appennino Modenese Regional park. It includes 64 permanent plots for plant species monitoring, distributed from timberline zone to the subalpine/alpine belt (1722-2000 m), that belong to the GLORIA project’s world network (GLobal Observation Research Initiative in Alpine ecosystems); The plots lie at the top of four summits, displayed along an altitudinal gradient, chosen following the GLORIA Target Region selection criteria. Furthermore, other 26 permanent plots, detached from the GLORIA project, have been settled on mount Prado. The observation and the long-term monitoring of vegetation and alpine plant species population started in 1999. The collection of soil temperature and osmotic potential started in 2001 and 2013, respectively. The site is resurveyed regularly to collect vegetation data (in term of presence/absence and coverage) and climatic data (temperature and osmotic potential data series recorded every 30 minutes by data loggers) in order to assess impacts of climate change on plant communities and single plant species of interest.

Located in Huitong County, Hunan Province (26°45´N and 109°30´E), Huitong National Research Station of Forest Ecosystem is affiliated to the Institute of Applied Ecology of Chinese Academy of Sciences. This region marks a transition from Yun-Gui Plateau to the hills along the southern bank of Yangtze River and belongs to the up reach of Yuan River, a tributary of the Yangtze. The altitude ranges from 300 m to 1100 m above the sea level. The densely grouped hills and valleys feature the topography in this region, which determining forestry to be the major method of land use in this County. The mother rock mainly consists of grayish green slate, metamorphic rock and sandy shale. With relatively deeper layer, red earth or reddish yellow earth are generally distributed from 300m to 600m above sea level, and mountainous yellow earth above 600m. This region has a typical climate of Central Subtropical Zone, with average annual temperature of 16.5℃. The annual rainfall and annual evaporation range from 1200 to 1400mm and from 1100 to 1300mm, respectively, with average relative humidity of 83% and 300 days of frost-free period. The zonal vegetation is evergreen broad-leaved forest typical of subtropics, with the major species component of Castanopsis spp.and Lithocarpus spp.

The Ploemeur-Guidel observatory (Britanny, France) is focusing on surface-depth relationships in a fractured crystalline geological context and oceanic climate. It is built on 2 sub-sites, one highly anthropized, the other in natural state. In Ploemeur, groundwater has been pumped since 1991, supplying more than 1 million m3 of clean drinking water annual at a sustainable rate. Such high productivity is explained the specific fractured network in granite and micaschists, draining deep geological layers (~400 m). Extracted water quality is very good, with limited nitrate concentration, in a region that has been strongly affected by widespread pollution. Guidel site is in a similar, but natural context. Deep iron-rich groundwater is upflowing, creating surface and deep groundwater-dependent ecosystems, and feeding a classified coastal wetland. Both sites have a very dense equipment to study rapid to long-term surface-depth exchanges: a flux tower, unsaturated zone monitoring, a network of ~50 shallow (<10m) and deep boreholes (>80m), hydrochemical, temperature and deformation. An well-characterized fractured experimental site offers the possibility to conduct experiments to test innovative instruments and develop new methodologies

The Yucheng Comprehensive Experiment Station (YCES) of Chinese Academy of Sciences (CAS) is located at the irrigation district of the Yellow River Basin in the Huang-Huai-Hai Plain, also called North China Plain. Physiognomy is characterized as hinterland covered mainly by fluvo-aquic soil (Fluvisol or cambisal) and salinized fluvo-aquic soil in the Yellow River Alluvial Plain. This region is dominated by warm-temperate semi-humid monsoon climate with ample energy and water resources. Historically, natural disasters such as drought, waterlogging, salinization, and wind erosion frequently occurred, resulting in vulnerable ecological environment and low grain production. Integrated improvements and managements were deployed in last several decades, and this region has become suitable for planting winter wheat, corn, cotton, and soybean with high yields in the Huang-Huai-Hai Plain. Research objectives and contents Objectives:  regional sustainable agriculture  rational utilization of natural resources such as water, land, climate, biomass, etc. Contents:  conducting long-term observations and experiments  understanding the mechanism of energy transfer and mass cycle in farmlands  developing models from point to regional scales  improving and developing instruments and measurement methods  improving agro-ecosystem managements  demonstrating research results and technologies Research achievements: Outstanding research results and massive experiment data have been achieved at the YCES. The achievements cover research fields of farmland evapotranspiration, crop water use, water transfer mechanism, experimental remote sensing techniques, regional agriculture demonstration, and technology transfer. More than 1,000 papers, 15 monograph books, and 5 data sets have been published. A number of awards were granted by national, CAS, and international academic organizations, for example,  Agriculture Prize granted by the Third World Academy of Sciences  Science and Technology Progress Award by Chinese Academy of Sciences  National Top Award of Science and Technology Progress

DHS has well protected monsoon evergreen broadleaf forest and its successional forests. Therefore, DHS is an ideal place to research successional processes and patterns of subtropical forest ecosystems, as well as to restore or rehabilitate the degraded forest ecosystems in subtropics of China.
