  • Hailun Agricultural Ecological Station located in Hailun city, Heilongjiang province, was established in 1978, briefly named Hailun Agro-ecosystem Station. The main research fields at that time were the optimal management of agriculture and advanced technology utilization in agricultural production. Chinese ecosystem research network(CERN) established in 1988 selected Hailun station as one of its components. The objective of Hailun station was to study the agro-ecosystem and sustainable development of agriculture in black soil zone in Northease China. Also, Hailun station was considered as one of components, when national field research net was built in 2005.

  • Huai Ma Nai is a small agricultural catchment (93 ha) of northern Thailand, 60 km from the city of Phrae, in a sloping land environment. The objective is to the impacts of land use changes, from mung bean and soya bean to maize, upon hydrological and sedimentary budgets. Agricultural practices are very intensive, based on high quantities of fertilizers, herbicides and pesticides, and mechanized cultivation. The mean slope is 12.9%%. Soils are thin Alfisols and Ultisols with sandy clay loam to clayey texture, high coarse fragment content, low pH, high bulk density and low-medium cation exchange capacity. Monitoring devices include an automatic meteorological station since 2001, and weirs and flume to monitor discharge from nested catchments, suspended sediment and bedload. More information is available on https://mtropics.obs-mip.fr/ and in the following paper: Valentin, C., et al., 2008. Runoff and sediment losses from 27 upland catchments in Southeast Asia: Impact of rapid land use changes and conservation practices. Agric. Ecosyst.

  • ICP forest monitoring plots: 0.5 ha of fenced stand + 20 m buffer area. Managment, data collection and reserch activities carried on by catholic university of Louvain (UCL)

  • The Forest of Meerdaal is situated on the Belgian loess belt about 25 km south-east of Brussels. It is an ancient woodland site, previously managed as coppice with standards, well known history (up to the middle ages). It is managed as multifunctional forest containing strict forest reserves with dense sampling grid (measured every decade). its proximity to the university make it an ideal research subject. Over the years many different studies have been conducted and documented.
