More than three decades has past since the launch of the first earth observing satellite, Landsat-1, in 1972. The accumulated images since then allow today retrospective monitoring of an ecosystem of a large area for a relatively long period. Observations of a large area for a long period are indispensable for an LTER. The change detection is an application of remote sensing, which can detect changes of forest canopies, or forest disturbances. With a time series of images, a history of the disturbances can be retrospectively extracted. Forest management today tries to mimic the natural disturbance regime so that the anthropological impacts would not exceed the tolerance of the ecosystem. In addition, anthropological disturbances have been observed to alter the succession and the biodiversity of stands afterward. Thus, the natural and anthropological disturbance regime is an indicator of the forest succession and the biodiversity that can be observed by the remotely sensed images. Remote sensing can be a good indicator that translates the results from intensive LTERs to a more straightforward manner so that the results can be extended to the all managed stands of the region. To prepare the images for the retrospective monitoring in future, we have to continue observation, archive them with metadata, and exchange information and ideas with people of different disciplines, as LTER participants always do for any other kinds of data.
