US LTER
The US National Science Foundation (NSF) in 1980 first coined the term "Long-Term Ecological Research”. In 1980 it initiated US-LTER and in 1993 also ILTER.

Currently, the research programs of the 28 US-LTER sites support ecological discovery on the influence of long-term and large-scale phenomenon. The network serves the wider ecological community by:
  • making almost 40 years of sustained observations publicly available,
  • developing and maintaining large-scale experiments, which provide starting conditions for process-level studies and help to parameterize and test models for conditions that may not currently exist
  • providing long-term context and deep knowledge of place for researchers working on shorter-term projects training hundreds of graduate students in interdisciplinary and collaborative team science
