Welcome to the Healthy Trees, Healthy Cities Initiative!


We are improving the health of America’s trees by engaging people in hands-on tree care and inspiring a new generation of environmental stewards. How do we do it?
We start with:

  • Assessing urban forest health to inform tree planting and management;
  • Training volunteers in tree stewardship and tree health monitoring;
  • Engaging youth and the public; 
  • Raising awareness about the importance of trees and what people can do to keep trees healthy through education and outreach; and 
  • Working with local partners to ensure the successful implementation of the program.

City Trees

When you imagine a forest, do you picture a city? You should! Nearly one-quarter of America’s tree canopy exists in our backyards, city streets and parks. Research has proven that trees are not just “nice” things to have—they are essential to healthy communities. Trees produce oxygen, clean our air, purify our drinking water and help prevent erosion. During summer months they keep cities cooler. Trees can also help cities mitigate air and water pollution, minimize crime, reduce asthma and improve our overall health, and increase property values. A city’s green infrastructure (trees, plants, parks) is as important as roads, sewers and water systems. When we take care of trees, they can help us live better for a long, long time.

Numerous studies have documented the value that trees and urban forests provide to urban residents.
