Long-Term Ecological Research (LTER) Sites manage a diverse array of ecological information resulting from research on ecological succession, disturbance, landscape ecology, elemental cycling, trophic structure, biodiversity, organic matter and primary productivity. Since its inception in 1980, the LTER Network has evolved from a primarily site-based research focus to a network and cross-site focus. Coincident with this evolution has been the development of metadata standards. Site-specific metadata standards and systems are being integrated through the development of metadata exchange standards and the revolution in network information servers.
