LTER
The Long Term Ecological Research (LTER) Network is a collaborative effort involving more than 1800 scientists and students investigating ecological processes over long temporal and broad spatial scales. The Network promotes synthesis and comparative research across sites and ecosystems and among other related national and international research programs. The National Science Foundation established the LTER program in 1980 to support research on long-term ecological phenomena in the United States. The 24 LTER Sites represent diverse ecosystems and research emphases. The LTER Network Office coordinates communication, network publications, and research-planning activities.
