LTER Finland (Finnish Long-Term Ecosystem Research Network) brings together the Finnish research sites and scientists that have conducted world-class research on long-term socio-ecological processes and problems into a coordinated Finnish research infrastructure, where the expertise and resources of both universities and main governmental research institutes are combined. These ecosystem research sites/platforms support, enhance and promote the inter-disciplinary investigation of long-term biodiversity and ecosystem processes at varying spatial and temporal scales. The long-term perspective helps to determine the impacts of drivers and pressures of environmental change and to investigate ecosystem processes and their response to environmental pressures. Finland is also intentionally stressing socio-ecological and socioeconomic research components in the national and international LT(S)ER networks.
