Extension
Connecting the university to our communities.
Partnering with communities and industries.
Cooperative Extension works to improve lives, communities, and the economy through a statewide network of knowledgeable faculty and staff. As a part of our land-grant university, Cooperative Extension plays a critical role in our mission to educate our communities and empower the next generation of experts to grow sustainable regional and global economies, and to develop new knowledge and technologies to benefit society.
Extension Faculty
Cooperative Extension faculty and our county agents connect research on plant production and diseases with gardeners and growers across the state, with a particular focus on Arizona's commercial crops and landscapes – including citrus, melons, grains, cotton, tree nuts, wine grapes, winter greens and vegetables, as well as drought-tolerant ornamental trees and shrubs.

Campus Arboretum
The University of Arizona campus is home to hundreds of tree and shrub species from arid climates on every continent on Earth. Most of the roughly 400 acres of our main campus are included in the boundaries of the Campus Arboretum. The trees within these boundaries, collected over more than a 125 year history, are an historical part of the university's land grant commitment to providing research and education to serve the needs of the state. The campus itself was used as a proving ground and living laboratory in sustainability, evaluating hundreds of new species and cultivars for their adaptation to this urban and arid region.
