The University of Tennessee Arboretum Society (UTAS) is a non-profit organization of volunteers throughout Tennessee, dedicated to furthering the objectives and programs of the University of Tennessee’s Forest Resources Research and Education Center’s Arboretum Project in Oak Ridge, Tennessee.

Chartered in 1965, the UT Arboretum Society has assisted the 250-acre research and education facility by providing volunteer support and funding for such projects as expanding plant collections, constructing educational facilities, and informing the public of the unique value and importance of the Arboretum. Recently, the Society has accepted the challenge of providing a portion of the operating funds needed to assure continued public access to the Arboretum.
