SUMMARY

The rates of greenhouse gas fluxes in northern peatlands are a sum of complex interactions between climate, temperature, hydrology, geochemistry, biochemistry and vegetation. Global change is predicted to have impacts on temperature and precipitation patterns, and therefore on peatland hydrology and vegetation. The resulting changes may act as a major triggering mechanism for greenhouse gas release. Thus understanding the species associations as a function of increasing trophic level and surface moisture would be important, as are spatial representations of species associations as inputs into models of greenhouse gas emissions. Remote sensing methods would becomevaluable in interpreting the vegetation structure and possible changes on northern peatlands. Geological Survey of Finland (GTK) has launched a prestudy to define the available cost-efficient remote sensing datasets to improve the
