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.  This program 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).  Homeowners and citizen stewards are also invited to participate at any level to support overall care of our community trees.   Visit our Class Schedule and select the “Urban Forestry” category from the dropdown list at the top of the page to view current classes.
