California’s Urban Forests in a Changing Environment

November 4, 2021 @ 5:00 pm - 6:30 pm

Dr. Ritter will describe his 20 years working to understand patterns and change in California’s diverse urban forests. He will describe research involving the California Urban Forest Inventory project and SelecTree. Climate change has and will continue to affect the state’s urban areas. Can we predict how urban tree species will respond to increasing temperature and variable precipitation? Ritter will discuss patterns and trends in tree selection and considerations for helping to ensure a healthy urban forest for California cities in a time of climate change and decreasing biodiversity. What should we consider when choosing a tree species for planting? Carbon sequestration potential, aesthetics, water use, provenance, and culture all play a role. Stay after the talk to pick up one of Dr. Ritter’s books or bring your own to have it signed.
