Long-Term Ecological Research (LTER)

prepared by Sean Perry

What is LTER?

LTER stands for “long term ecological research” and involves research and analysis conducted on ecological issues that exist for large periods of time and occupy vast geographical areas. A network of 6 LTER sites was created by the National Science Foundation (NSF) in 1980 to help document and analyze ecological change over an extensive amount of time. The number of LTER sites has now grown to 26, spanning from Alaska to the Caribbean, with two additional sites in Antarctica.

LTER Sites

All sites are supported by the National Science Foundation.


The information gained from LTER research can benefit the health, productivity, and well-being of the global environment. Specifically, the information helps predict future biological responses to change, provide additional data on important issues such as climate change, and makes evaluation of the pace on ecological change possible. Examples would include data about human impacts on land, such as with the research being done in the Andrews Forest LTER in the Pacific Northwest, where thousands of acres of old-growth forest were cut down in the past for timber production. At this site, data is being collected on how the forest is recovering from the cutdown by looking at the stages of tree structure, vegetation composition and spatial heterogeneity of the forest. Another example is of the research being done in Alaska at the Arctic LTER site. At this site, data is being collected on the shrinking amount of permafrost due to rising global temperatures and how this affects the global atmosphere, since permafrost holds massive amounts of carbon.
