Trees: Critical Green Infrastructure
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.
Light refreshments provided. Please bring your reusable water bottle and coffee mug.
