Long-Term Ecosystem Research (LTER) is an essential component of world-wide efforts to better understand ecosystems. Through research and monitoring, LTER seeks to improve our knowledge of the structure and functions of ecosystems and their long-term response to environmental, societal and economic drivers.
LTER contributes to the knowledge base informing policy and to the development of management options in response to the Grand Challenges under Global Change.
LTER-Europe was launched in 2003 as the umbrella network for Long-Term Ecosystem Research (LTER) in Europe. It's members are national networks operating a wide range of research and monitoring sites as well as larger platforms for socio-ecological research.
