Balboa Park Tree Stewards

The Conservancy is preserving, protecting, and renewing Balboa Park’s urban forest with the help of tree lovers like YOU.


Balboa Park’s collection of more than 15,000 trees is an extraordinary asset to our region. However, their adequate care requires dedicated support from the community. Tree Stewards are specially trained to monitor newly planted trees, general health conditions of existing trees, soil moisture surrounding new trees, including identifying irrigation needs, and possible pest infestation. The Balboa Park Conservancy proudly partners with Tree San Diego to monitor Balboa Park trees through our volunteer Balboa Park Tree Stewards program. Join our team and have another great reason to spend more time in beautiful Balboa Park!

Please email our Volunteer Coordinator for more information at There is an active waitlist for this program.
