TreePeople is an environmental nonprofit that unites the power of trees, people and nature-based solutions to grow a sustainable future for Los Angeles. Simply put, our work is about helping nature heal our cities.

Our mission

TreePeople’s mission is to inspire, engage and support people to take personal responsibility for the urban environment, making it safe, healthy, fun and sustainable and to share the process as a model for the world.

Trees + people

Our early efforts in the 1970s focused on educating and inspiring people to plant and care for trees. Why? Because more trees means cooler temperatures, cleaner air, replenished groundwater supplies and a safer, more beautiful city.

Expanding the tree canopy over L.A. remains one of our central goals. But the worsening impacts of global warming and the looming threat of water shortages tell us we need to do more.

Trees + people + nature-based solutions

L.A.’s urgent environmental challenges led TreePeople to ask an important question: In places we can’t plant trees – e.g., where buildings and parking lots cover the land – what else can we do to green our city? Earth’s life-giving forests inspired a solution!

We can protect our natural resources and ensure clean and abundant water in our city by using solutions that re-create the functions of a healthy forest in an urban setting. Examples of these nature-based solutions include permeable paving, French drains, swales, rain barrels, cisterns and other relatively simple “forest-mimicking” innovations.

Our task now is to assist communities to put these nature-based solutions into action alongside healthy, well-cared-for trees in order to create a Functioning Community Forest in every neighborhood of L.A.
