Integrated Monitoring (IM) is the Finnish contribution to the UN-ECE ICP Integrated Monitoring of Air Pollution Effects on Ecosystems; a long-term international ecosystem monitoring programme. The agreement to participate in the programme has been made by the Ministry of the Environment and Finland contributes data from four IM catchments (Valkea-Kotinen, Hietajärvi, Pesosjärvi and Vuoskojärvi). These catchments are headwater catchments located in national parks or reserves and surrounded by forest. The effects of management, agriculture and traffic are therefore negligible and the only source of air pollution is from long-range transported emissions. The IM catchments therefore represent background areas of air pollution and deposition to boreal coniferous forests in Finland.<P>
As one of the participating institutes, Metla has agreed to carry out a number of the IM permanent plot subprogrammes. These cover the stand (measurement and mapping, forest condition, needle chemistry and litterfall), soil (soil and soil water chemistry, soil microbiology), and deposition (throughfall and stemflow). Implementation is in accordance with the Manual For Integrated Monitoring. Data is submitted to the ICP Programme Centre (located at the Finnish Environment Institute) according to a strict reporting protocol. In contrast to other Metla ecosystem studies, this project will enable mass balance budgets and nutrient cycles to be made for natural and mixed stands. Because the IM programme is guided by a manual and protocols, the data should be directly comparable between catchments and with that collected by other participating countries. The data collected by Metla will be used to monitor the response of forest ecosystems to internationally agreed emission reductions and in the application and development of biogeochemical and biological/bioindicator models.
