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. Through our unique model, we listen to, equip, and train volunteers to green our urban spaces and mountains. TreePeople has activated millions of people in planting and caring for millions of trees.

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.

What We Do

Forestry

We restore ecosystems, plant trees, and incorporate nature-based solutions throughout our Southern California streets, mountains, and everywhere in between.

School Greening

We create green learning environments that enhance academic achievement, support health and well-being, and create safe places to play in nature. Through partnerships with school communities and districts, we advocate for, implement, and manage school greening projects to protect students from extreme heat, air pollution, and polluted water.

Education & Youth

We provide students, teachers, and the school community with the knowledge, tools, and support they need to create environmental change.

TreePeople’s 45-acre headquarters on Mulholland Drive in the Santa Monica Mountains offers nature trails, experiential education, and cultural programming and is home to TreePeople’s Native Plant Nursery.

TreePeople Land Trust

We steward more than 3,000 acres of land in the Santa Monica Mountains–protecting these spaces for the benefit of future generations. Programs include public recreation, environmental education, scientific research, and more.
