Responsible Unit: 
Campus Arboretum

Purpose and Summary

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.


The University of Arizona Arboretum comprises all space on which the University has developed facilities: the Main Campus from Euclid to Campbell Avenues and from Sixth Street north, across Speedway, to the space surrounding the Banner University of Arizona Medical Center. All plantings on UA property, adjoining UA buildings, and/or defining University open space, in Pima County, Arizona, may be considered as a part of the University of Arizona Arboretum.


The mission of the University of Arizona Campus Arboretum is to preserve, manage, enhance, and expand a vital collection of plants in an active urban Sonoran Desert setting, and to showcase the historic, aesthetic, environmental, economical, and educational value of these plants within our community and the American Southwest. Plants accessioned into the University of Arizona's Collection must assist in fulfilling this mission. 

To accomplish this mission on the grounds of the University of Arizona requires flexibility. The Campus Arboretum recognizes the need to work with Planning, Design, and Construction, Facilities Management, and other interrelated units to develop efficient and practical methods for realizing the goals of stewardship of, and education about, the campus plant collection as it contributes to the larger Tucson urban forest.

The complete policy is housed on the Campus Arboretum website.
