The main University of Arizona campus has nearly 9,000 woody plans and cactus on record, representing about 550 species from six continents.
There are many trees throughout campus with significant history, including some who have been in campus since its origins.
"In the early years of the university, during territorial period, one of the major needs in the state was economic growth," said Tanya Quist, Ph.D., director of the UA Campus Arboretum. "Many of our faculty in the College of Agriculture and Life Sciences travelled worldwide to bring back plants that could perhaps be introduced here as an agricultural commodity."
