Under this scheme the monitoring of air pollution effects on forests is carried out by participating countries on the basis of the systematic network of observation points (Level I) and of the network of observation plots for intensive and continuous monitoring (Level II). These monitoring activities under Forest Focus continue from the network and plots established and implemented under Council Regulation (EEC) No 3528/862 and Regulations (EEC) No 1696/873 and (EC) No 1091/944.
The monitoring programme of air pollution effects is linked to the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forest (ICP Forests). ICP Forests reports to the working Group on Effects of the Convention of the Long-Range Trans-boundary Air Pollution (CLRTAP) of the United Nations Economic Commission for Europe (UN-ECE).
Forest Focus Article 15(1) stipulates that the Member States shall annually, through the designated authorities and agencies, forward to the Commission geo-referenced data gathered under the scheme, together with a report on them. For managing the data the European Commission Joint Research Centre (JRC) has implemented a Forest Focus Monitoring Database System. The system was developed and realized under contract by a Consortium, coordinated by I-MAGE Consult with Nouvelles Solutions Informatiques s.a. (NSI) as consortium partner and the Bundesforschungsanstalt für Forst- und Holzwirtschaft (BFH) as sub-contractor.
The designated authorities and agencies, the National Focal Centres, submitted annually to the JRC their observations made on Level II plots. Data are submitted via a Web-Module specifically designed for the task as part of the Forest Focus Monitoring Database System. The data are then validated in a process of three stages of checks of various aspects of the information submitted before entering the Forest Focus Monitoring Database (FFMDb).
