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.
You can transform our region—one tree, one street, one community at a time. We are all TreePeople!

As school greening work heats up, surface temps cool down

Have you ever strolled down your street and thought, “Wow, these trees could use a little TLC”?

Life in the big city is REALLY tough for trees. While trees in the wild often live 100 years or more, the average lifespan of an urban tree is just 19 to 28 years, according to the USDA.
