Nature tour highlights historic importance of California oak trees during the fall

The Shumway Oak Grove Regional Park in Stockton launched an autumn nature walk for the community to get an inside look at how important California's historic oak trees are, especially during the fall.

Carolyn Dougherty is a volunteer naturalist at Oak Grove Nature Center and led a group of people on Sunday morning for a new nature walk, which kicked off this fall: "Autumn Among the Oaks".
