Trees: Critical Green Infrastructure

Cool Cities STL Pop-up

Trees are a powerful and important form of green infrastructure. They control stormwater, reduce air and water pollution, reduce urban heat, increase biodiversity, and improve the well-being and aesthetic appeal of our communities.

Learn about efforts underway in Clayton to preserve and restore urban canopy, and other initiatives to increase and maintain trees throughout St. Louis County.

Thank you to our hosts at the City of Clayton!
