The Urban Forestry Certification Program was developed with support from the Arizona Department of Forestry and Fire Management to train citizens of southern Arizona to become better stewards of our urban forests.  Homeowners and citizen stewards are invited to participate at any level to support overall care of our community trees.  This program also offers professional development for landscape and nursery professionals as well as anyone preparing to take the ISA Certified Arborist® exam (but does not replace independent study for this exam).   See available classes below or visit our Class Schedule and select the “Urban Forestry” category from the dropdown list at the top of the page to view current classes.
