Who We Are
TreePeople inspires and supports the people of LA 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 Los Angeles.
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 Los Angeles’ 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.
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.
