That’s why Forever Balboa Park prioritizes building and maintaining Balboa Park’s urban forest for generations to come. In the last 5 years, Forever Balboa Park has planted more than 700 trees. Annually, our expert Tree Stewards support San Diego Parks and Recreation to monitor and maintain the 16k+ trees throughout Balboa Park. It is Forever Balboa Park’s plan to continue growing the urban forest in San Diego with tree plantings, maintenance and expert support to Parks and Recreation.
