The mission of the Campus Arboretum at the University of Arizona is to provide conservation and stewardship of urban trees through research, education, and outreach.
The purpose of the Collections Policy is to provide guidance and focus to those charged with the planning, development, and management of the plant collections of the University of Arizona Campus Arboretum, with the aim of optimizing utilization of available resources to realize the Campus Arboretum's mission through effective and appropriate collections development.
The primary collections of the UA Campus Arboretum are its collections of living plants. A secondary, voucher collection of plants is housed at the University of Arizona Herbarium (ARIZ), a unit mandated by the State of Arizona. The above-cited purposes govern the Arboretum's collections of living plants.
