Who We Are

Born from the efforts of a teenager over 50 years ago, TreePeople inspires and supports the people of Southern California to come together to plant and care for trees, harvest the rain, and renew depleted landscapes. TreePeople has activated more than 3 million people in planting and caring for more than 3 million trees.

TreePeople unites with communities to grow a greener, shadier, and more water-secure city in homes, neighborhoods, schools, and the local mountains. We work with both educators and students to train the next generation of eco-conscious leaders. We steward thousands of acres of land—maintaining habitats and protecting land from development. We develop original, actionable research that drives science-based policy. We train volunteers on the ground to help build a greener Southern California.
