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.

  • 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

  • COVID safe


What will I do as a Tree Steward?

Depending on capacity and interests, Tree Stewards may 

  • Provide new tree care, especially watering

  • Care for new street trees in and around local communities

  • Provide on-the-spot skills training in the field to other volunteers
