Who We Are
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.
Born from the efforts of a teenager over 50 years ago, we have involved more than 3 million people in planting and caring for more than 3 million trees.
We unite with communities to grow a greener, shadier and more water-secure city at homes, neighborhoods, schools and in the local mountains. We work with volunteer leaders using our unique Citizen Forester model, and we influence government agencies for a healthy, thriving Southern California.
Our Focus Areas
Community
Working towards environmental and social justice among environmentally stressed communities.
Education
Providing students, teachers and the school community with the knowledge, tools and support they need to create environmental change.
Forestry
Restoring ecosystems, planting trees, and incorporating nature-based solutions from Southern California urban streets to our greater watershed.
Parks & Trails
Protecting and stewarding natural parks and open spaces.
Policy & Research
Conducting cutting-edge research and facilitating policies that support nature-based solutions.
