The highly standardized measurements needed in ICOS require specific and precise protocols that standardize the instruments, methods and processing for all the variables of interest. These protocols need to be in line with the existing international standards and need to be harmonized with ongoing initiatives in other networks.
The ICOS Ecosystem Monitoring Stations Assembly (MSA) decided to work on actual and future protocols with the organization of specific Working Groups open to the whole scientific international community, including the technical experts and others networks representatives. The Ecosystem Thematic Centre is responsible for the protocol preparation monitoring and for their final implementation and dissemination.
All scientists willing to contribute to the discussion and definition of best practices and protocols are encouraged to register for the WG of their interest. To receive the last version of the protocol draft please contact the protocol coordinator reported below. When the final draft will be approved it will be notified in the specific WG page. The WG will however remain active for possible future developments and improvements.

WG Lateral Fluxes
This WG includes all the lateral fluxes and their causes and impacts. Exports due to harvesting and grazing, inputs such amendments and residuals management, soil disturbances and more in general all the biotic and abiotic disturbance effects are considered, including the site history and description. For this reason the WG (coordinated by Matthew Saunders) is organized in six sub-groups strongly interconnected:
-
Site characterization (history, fetch, maps, inventories). Coordinator: Matthew Saunders (saundem@tcd.ie)
-
Export (harvesting and grazing). Coordinator: Sigrid Dengel (sigrid.dengel@helsinki.fi)
-
Site amendments (fertilisation, liming, herbicide/pesticide/fungicide, residue management, irrigation). Coordinator: Christine Moureaux (christine.moureaux@ulg.ac.be)
-
Soil disturbance due to management (tillage, sowing/planting, rolling, drainage, land use change). Coordinator: Matthew Saunders (saundem@tcd.ie)
-
Biotic disturbance events (insects, disease, pathogens). Coordinator: Leonardo Montagnani (leonardo.montagnani@unibz.it)
-
Abiotic disturbance events(extreme climatic events e.g. water [drought/flooding], wind, fire). Coordinator: Matthew Saunders (saundem@tcd.ie)
