U.S. Long-Term Ecological Research (LTER) Network

The Long Term Ecological Research (LTER) Network is a collaborative effort involving more than 1100 scientists and students investigating ecological processes over long temporal and broad spatial scales. The LTER Network promotes synthesis and comparative research across sites and ecosystems and among other related national and international research programs. The National Science Foundation (NSF) 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: LTER Network Office (NET) H.J. Andrews Experimental Forest Arctic Tundra Baltimore Ecosystem Study Bonanza Creek Experimental Forest Cedar Creek Natural History Area Central Arizona-Phoenix Coweeta Hydrologic Laboratory Florida Coastal Everglades Georgia Coastal Ecosystems Harvard Forest Hubbard Brook Experimental Forest Jornada Basin Experimental Range W.K.
