The research staff of the USDA Forest Service - Coweeta Hydrologic Laboratory as well as the University of Georgia and other cooperating institutions have been archiving soil and plant tissue samples since 1970. Historically, scientists have been solely responsible for the collection, analysis, and long term storage of samples. In an effort to better organize and to make these valuable plant and soil samples more accessable, a sample archive was established at Coweeta in 1997. Online documentation to the left outlines the current policies and procedures for the addition to and usage of samples in the physical archive.
