Tree San Diego is a nonprofit dedicated to increasing the quality and density of our urban forests for the benefit of people, the environment, and the future. To support tree planting efforts, Tree San Diego offers a Tree Steward Certification Program that provides trainees with the understanding of tree benefits, tree care and maintenance techniques, tree tracking and mapping tools, and industry best practices that empower the next generation. This program is open to anyone who wants to learn more about the benefits and care of trees and help educate their local community about our urban forest.
