One of the primary values of long-term ecological data sets is the crucial background information they can provide for experimental research, especially whole ecosystem manipulation.

In 1987 NASA began field studies called FIFE, the First ISLSCP Field Experiment (ISLSCP = International Satellite Land Surface Climatology Project).

The Virginia Coast LTER Program of the University of Virginia is focused on the Virginia Coast Reserve (VCR) of the Nature Conservancy.

LTER research at the Kellogg Biological Station (KBS) is centered on row-crop agricultural systems, with particular emphases on ecological constraints to agronomic productivity and on the environme

The overall goal of the Hubbard Brook LTER project is a better understanding of the response of northern hardwood-conifer watersheds to large-scale disturbance.

The newly established Bonanza Creek LTER site in Fairbanks, Alaska, will examine successional changes in controls over ecosystem function in upland and floodplain taiga forests.

The site is located at 69°N near Toolik Lake, an oligotrophic kettle lake in the northern foothills of the Brooks Range, Alaska.

Featured this month are the five new LTER sites.
