LTER Sweden is a network of Swedish field stations conducting environmental research and monitoring. There are currently 19 LTER stations in Sweden. LTER Sweden is an umbrella for a number of established and highly instrumented stations for ecological research and monitoring. It is an open network and all Swedish research stations that fulfill some basic requirements are welcome to apply for membership. The Swedish LTER network provides its members opportunities for national and international cooperation, and access to state-of-the-art infrastructures for ecological field research through the European LTER network. LTER Sweden was founded in June 2010. The LTER Sweden network aim at: reinforcing Swedish environmental research and assessment by building capacity for data sharing and research cooperation between long-term monitoring and research stations and their associates. providing scientists with opportunities for research and environmental assessment at greater spatial and temporal scales than possible with data from one individual monitoring station. encouraging grant applications for research and environmental assessment activities that are not possible to conduct without the Swedish LTER network or international cooperation with other LTER organisations. encouraging new research areas and multidisciplinary research emerging from the network structure.
