Tree Talk Webinar: The Surprising Benefits of Trees—improved health and reduced crime

Wednesday, September 18, 6:30-8 pm, Zoom link, free

Urban trees provide a wide range of benefits from the intuitive—providing shade, for example—to the surprising: improved human health and reduced crime. This talk will summarize these findings and show that trees are an under-appreciated, but essential, part of our public-health and public-safety infrastructure. Dr. Donovan, our speaker, received his PhD in forest economics. He has worked as an economist for the USDA Forest Service in Alaska and Oregon. His primary research focus is quantifying the benefits of urban trees.
