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.

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.

Earlier this month, TreePeople […]

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 […]
