become a TREE steward

Tree San Diego's Tree Steward Certification Program is open to anyone who wants to learn more about the benefits and care of trees and help educate their local community about San Diego's urban forest. 


Who can be a Tree Steward?

Anyone! However, children under 14 will need adult supervision.

What does it mean to be a Tree Steward?

A Tree Steward is a volunteer who has completed the Tree San Diego Tree Steward Certification Program. 

Tree Stewards are trained and certified in various skills that they can use to preserve and enhance their neighborhood trees. When you become a Tree Steward, you are joining other San Diegans who are using their skills and knowledge for the betterment of their community.

How much does it cost?

We ask for a $15 donation for each training module attended.  


When do the trainings take place?

Tree Steward workshops are offered the 3rd Saturday of each month from 10am-noon. During that time you will learn how to:

  • Plant, water, maintain, and monitor tree health

  • Communicate and advocate for trees in their local community

  • Learn the benefits of urban forests

  • Identify native species and discuss proper care techniques

What are the benefits of a virtual educational workshop?

  • Comfort of your own home

  • No commute needed

  • Convenient

  • Quarterly refresher courses available to maintain certification

  • COVID safe


What will I do as a Tree Steward?

Tree Stewards are expected to make a minimum 1-year commitment in which they contribute 20 hours per year of community service to include:

  • 2-hour online training
