Who We Are
Born from the vision of a teenager more than 50 years ago, TreePeople inspires people to come together to grow a more climate-resilient Southern California. We have planted and cared for millions of trees, restored thousands of acres of fire-scarred wildlands, and helped to educate hundreds of thousands of environmentalists.
When California experiences climate emergencies, TreePeople researches and implements sustainable solutions to protect and restore natural resources. When fires burn, TreePeople restores native ecosystems to grow more resilient wilderness areas and communities. When communities face extreme heat, TreePeople plants and distributes shade trees. When schools are covered in asphalt, TreePeople greens schoolyards. When students worry about the future, TreePeople provides tools and education to train our next generation of environmental leaders. As the world faces increasing threats from climate change, TreePeople helps unite communities around actionable solutions.
What We Do
Community Forestry
Through our urban planting and tree care events and tree distributions, we work with communities to increase tree canopy and green space where it’s most needed, building resilience in the face of climate change.
Restoration & Conservation
TreePeople trains and mobilizes thousands each year to increase the climate and fire resilience of Southern California’s wildlands. By cultivating native plants in our nursery, removing invasive species, prioritizing biodiversity, and providing long-term site management, our comprehensive restoration model helps facilitate long-term recovery for degraded sites and burn scars, assuring they are healthier and more fire-resilient for future generations.
Urban & School Greening
TreePeople’s Green Infrastructure program partners with communities to transform our urban landscapes into greener, healthier spaces. We work across schools, parks and public spaces, private parcels and streets, and turn lawns and paved areas into thriving landscapes. Our team designs, implements, maintains and advocates for green infrastructure projects that help capture water, reduce heat, and improve community well-being.
Education & Outdoor Equity
Every year, TreePeople engages tens of thousands of students in parks and on campuses to teach environmental literacy and provide hands-on, actionable solutions to our climate crisis. We also offer tools to teachers so they can continue to deepen students’ understanding of our local ecosystems.
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.
Policy & Advocacy
TreePeople works from the policy level to the grassroots level to facilitate science-based policies, incentives, and applicable demonstration programs to transform Southern California utilizing nature-based solutions.
Research
TreePeople’s Research Department has been at the forefront of urban environmental science for over a decade, producing scientific reports that inform and inspire action on issues like water security, soil, drought resilience, and urban heat.
Water
TreePeople supports communities in rethinking the way we manage water by modeling best watershed management practices and engaging people through education and participation in community retrofit projects. This demonstrates how our schools, homes, streets, and alleys can be transformed to improve water quality, increase water supply, and provide community benefits. We show how simple changes can protect our water, reduce pollution, and create greener spaces.
