University of Arizona Campus Arboretum

This channel is dedicated to promoting stewardship and conservation of arid urban trees in arid and semi-arid climates.

The Campus Arboretum is a living collection of trees planted throughout the nearly 400 acres of open spaces on the main University of Arizona campus in Tucson, AZ. The collection evolved as trees from arid climates around the world were planted on campus as a series of research experiments aimed at finding drought tolerant plants.
