The University of Arizona Campus Arboretum (arboretum.arizona.edu) is home to hundreds of tree and shrub species from arid climates around the world. Most trees within the main campus are included in a collection that has grown for more than 125-years out of the University's land grant commitment to serve the needs of the state. Campus grounds have been used since 1891 to test arid-adapted species, thus serving as a living laboratory for urban sustainability and as a living laboratory promoting conservation and stewardship of urban trees.
The Krutch Garden on the University of Arizona’s Mall is a portion of the original campus cactus collection now dedicated to naturalist, Joseph Wood Krutch. The Sonoran native plants featured in the Krutch Garden can be explored through a self-guided tour found here.
The USA National Phenology Network (USA-NPN; usanpn.org) and the Nature’s Notebook (naturesnotebook.org) citizen science program sponsor the Tucson Phenology Trail. Join thousands of individuals who provide valuable consistent observations on the timing of plant and animal life cycle events for scientists, educators, policy makers, and resource managers to understand species’ response to climate change. Register for Nature's Notebook on the USA-NPN website and join the UA Campus Arboretum Group. The Old Main and the Krutch Garden observation sites will be automatically loaded in your Observation Deck.
To help you begin monitoring, check out the USA-NPN’s Botany Primer and other useful, related resources here. For educators interested in site-based, experiential, community learning check out the Phenology Walks and Trails Guide and consider participating in the Local Phenology Leader Certification Course.
The USA National Phenology Network’s Tucson Phenology Trail website has information about the plants being observed via Nature’s Notebook. View a map of the plants marked for observation in the Krutch Garden, here.
