 ===== What is LTER? ===== ===== 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 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.

 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. ​ The information gained from LTER research can benefit the health, productivity,​ and well-being of the global environment.

 +===== Jornada Basin LTER =====
 +The Jornada Basin LTER exists near the southern New Mexico city of Las Cruces. It was established in 1982 to investigate desertification processes in the Chihuahuan desert. According to their website, significant progress has been made in understanding these processes. Specifically,​ research has been done on vegetation trends in 5 different habitats within the Chihuahuan desert: black grama grassland (Bouteloua eriopoda), creosotebush scrub (Larrea tridentata),​ mesquite duneland (Prosopis glandulosa),​ tarbush shrublands (Flourensia cernua)and playa. Another research focus has been on soil development within the Jornada Basin and Range. Studies have been done on alluvial materials that exist in broad valleys between parallel mountain ranges. These kinds of valleys exist not only in the basin and range, but throughout Arizona, Nevada and into the Mojave Desert of California.

 +===== Andrews Forest LTER =====
 +Located in the western Cascade mountains of Oregon, the Andrews Forest LTER was one of the original 6 LTER sites created by the National Science Foundation in 1980. It was originally established as an experimental forest by the US Forest Service in 1948 when most of the old-
 +growth forest still existed. Throughout the years, research focus has ranged from old-growth harvest to the function and structure of forest ecosystems. Currently, research is being done on the ecological response of forests to land use, climate change, and natural disasters.

 +===== ILTER: International Long Term Research Network =====
 +In addition to the U.S. LTER, the ILTER was established in 1993 to promote global long-term ecological research. The network consists of forty member networks from countries that span the globe, such as Brazil, South Africa, and Mongolia. The governing body of ILTER meets annually at a meeting hosted by one of the member networks.
