Good Health Grows on Trees

The influence of nearby nature on public health

Nearly forty years of research and thousands of scientific studies have shaped our understanding of the extraordinary health benefits of urban trees and green spaces. Urban nature has been shown to reduce cardiovascular disease, mental illness, ADHD, diabetes, respiratory illness, and asthma; support immune function and family dynamics; increase healthy birth weight and opportunities for physical activity; and much more. According to Dr. Kathleen Wolf [PDF exit DNR], increased investment in urban nature could result in billions of dollars saved in avoided healthcare costs, avoided costs due to crime, and increased lifetime incomes of high school graduates.

Scroll down for our list of the top resources on the health benefits of trees, including websites that compile cutting-edge research, brochures of various lengths, webinars, and organizations and movements that you can join. You’ll also learn how the Wisconsin DNR has been working to educate and involve the public in this research, from our inaugural Good Health Grows on Trees Conference in 2019 to our current projects.

What we do

In May 2019, the Wisconsin DNR Urban Forestry program hosted the first ever ‘Good Health Grows on Trees: The Influence of Nearby Nature on Public Health’ conference. With the goals of building relationships and sharing information across disciplines, the conference attracted a diverse group of 125 participants from the fields of public health, landscape architecture, urban and regional planning, and urban and community forestry. Keynote speaker Dr. Kathleen Wolf [exit DNR] joined us from the University of Washington-Seattle and was followed by insightful presentations from Wisconsin-based researchers. Attendees closed out the afternoon with an interactive session where they connected and collaborated with others from various professions and areas of the state.

Building on the momentum created by the conference, we continue to facilitate conversations between community forestry and public health, and to share knowledge and resources with researchers in the field, both locally and nationwide. Future events are in the works!

We are also developing a presentation on the health benefits of nearby nature that we will give to interested groups. Please contact Patricia Lindquist if you would like to learn more about this presentation.
