We Offer Free Guided, Self-Guided and Virtual Tree Tours!

We offer guided trees tours throughout the academic school year (usually Sept. - May). There are printed self-guided, virtual online tours, and mobile-enabled self-guided tours available as well. See our tree tours page for more information. 


We impact Arizona and a growing global community as we exercise the University's Land Grant mandate to serve and inspire through public outreach. The University of Arizona Campus Arboretum provides a wealth of knowledge through its online resources, statewide programs to audiences of all ages and free tree tours and events offered to Tucson visitors and local residents.




Tree Database and Maps make botanical information available to the public. The living plant collections on campus are a resource for a wide array of activities including those relating to local and international research, formal education, and various outreach programs. To serve as an effective resource, detailed accessions data and photography for each campus plant is maintained in a geodatabase. You can search for trees by characteristic, browse the species list and descriptions, find the location of campus trees on our Tree Map, or take a self-guided tour using your mobile device.  


Tree Care Guidance are held throughout the state of Arizona to educate landscape professionals and residential home owners about science-based tree selection and management. From these workshops, we have created a summary guide of proper selection and planting practices  for you. Other presentations on this topic created by University of Arizona Cooperative Extension Specialists and Agents are also available for your reference. 




The Tree Stewards Program  is run through a partnership with the Pima County Cooperative Extension Master Gardeners. Master Gardeners complete workshops and training to qualify as tree educators. They then volunteer as docents for tours and serve as trainers for students interested in leading tours.


Phenology Trails and Training Program is a partnership with the National Phenology Network. You can join thousands of other individuals who are providing valuable observations that scientists, educators, policy makers, and resource managers are using to understand how plants and animals are responding to climate change and other environmental changes. Register for Nature's Notebook on the NPN website and search for UA campus sites including Old Main and the Krutch Garden. Check out the Botany Primer and other useful, related resources here.  For educators interested in site-based community learning and experiential learning, check out the Phenology Walks and Trails Guide.


The Poetry Center  is a wonderful place to visit on campus! Among their many community offerings, they provide a unique voice to communicate the value of the Campus Arboretum and all urban trees. To learn more about the "po-eh-TREE" programs, click here!

Linking Edible Arizona Forests, or LEAF on the UA Campus, is a non-profit program aimed at promoting sustainable food systems by harvesting and using edible products from urban trees. The UA Campus program is the result of a wide array of community and campus partners and yields harvesting opportunities and edible products for resale. To learn more, click here!


The Campus Arboretum offers workshops, presentations and eductional outreach activities at schools and community groups to promote environmental literacy and sustainable landscape management. Check out our events calendar  for more detail or look for other ways to get involved and spread the word!
