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 40 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
Working towards environmental and social justice among environmentally stressed communities.
Providing students, teachers and the school community with the knowledge, tools and support they need to create environmental change.
Restoring ecosystems, planting trees, and incorporating nature-based solutions from Southern California urban streets to our greater watershed.
Park & Trails
Protecting and stewarding natural parks and open spaces.
Policy & Research
Conducting cutting-edge research and facilitating policies that support nature-based solutions.
Green Our Schools
We create green learning environments that enhance academic achievement, healthy schools, and thriving nature by advocating for, implementing, and managing school greening projects to protect students from extreme heat, air pollution and polluted water.
Volunteering with TreePeople is fun and rewarding. Our events empower you with the support, training and tools you need to be an engine of change. Join us each week as we plant and care for trees throughout Los Angeles, remove invasive species and maintain our projects throughout Southern California.

Let’s Green Riverside – TreePeople Returns to the Inland Empire
In the summer of 1973, the first stirrings of what would become TreePeople began in the mountains above Riverside, California. Those early efforts by teenagers to help protect and restore the San Bernardino National Forest soon blossomed into Southern California’s largest environmental movement—mobilizing 3 million volunteers to plant 3 million trees. Earlier this month, TreePeople…
Tree Planting in Lynwood Begins!
If you asked TreePeople staff what they remember most from our tree planting events it would probably be the smiles of children getting the chance to play in the dirt, or the stories of community members on why they chose to spend their weekends volunteering and giving back. But what happens behind the scenes to…
New Trees Take Root in Watts
It’s 8:30 on a Saturday morning. The late summer sun beats down on a grid of blacktop. It’s already hot enough that the stop sign at the end of the block is almost hidden by a mirage. But something is different about today. Trees line the sidewalk on both sides of the street, waiting to…
