Targets of integrated environmental
monitoring
With the aid of integrated environmental monitoring
changes of processes and functions in the
ecosystem are to be early diagnosed (early warning
function). This is connected with the possibility of
taking counteracting measures before grave
environmental problems will become obvious. In            Essential results of the pilot project:

monitoring     programmes        and  measurement            are to be collected or to be provided by the existing
networks is to be increased by a stronger                    measurement and monitoring programmes for
coordination of the current monitoring activities and        integrating interpretations
