This dataset includes exports from what was known as LTER siteDB and from the ILTER database. Both efforts are network databases that are intended to provide a common cross-site view and simple access to LTER site descriptions, history, research themes, and parameters specific to the respective research locations. These exports contain somewhat duplicated information and have a varying degree of completeness. Both provide a snapshot in time of site profiles containing key information on research, history, institutional affiliations, and location for each LTER site, plus average biotic and abiotic site characteristics, and ecosystem classifications.
