Citizen Arborist Program

Is the health of the urban forest important to you?

Want to be a leader in your community through the planting and care of trees?  Want to be part of a growing group of “experts” representing TreePeople to help grow a greener Los Angeles?  If this sounds like you, take our highest level of training to become a TreePeople Citizen Arborist!

Citizen Arborists help support the work of TreePeople by organizing and running tree planting and/or tree care events in their community. They are required to complete a FREE 7- session training in tree science, identification, planting, pruning and basic tree care. The training includes how to get permits, organize an event in your community and work with volunteers. This includes a written exam and field test to become TreePeople certified.

Fun monthly events, designed just for the Citizen Arborist Team, are also offered to promote camaraderie and deeper learning. 

Apply online. Upon acceptance, we will send you a confirmation letter of your admittance into the program with information about the upcoming class schedule.

Training Sessions:

All classes are Saturdays from 9 AM to 1 PM, except Sunday October 5

  • Fall 2014 – September 6, 13, 20; October 5, 11, 18, 25


  • You must be at least 16 years old.

While the program is free, it is meant for those who want to be trained as a resource for their community - organizing tree planting and tree care events. If you are a match for the program we will send you a confirmation of your admittance and information on the upcoming class schedule. Other applicants will be directed to a training that best fits their goals.
