<strong> Advice on caring for oaks:</strong> Do you know how to care for the oak trees in your yard? Forester Bruce Hagen and oak ecologist Steve Barnhart will show you how during a class Oct. 19 at Pepperwood Preserve in Santa Rosa.
The class will offer a comprehensive foundation for maintaining the health of oak trees via landscaping, irrigation and managing the growing environment. It will conclude with a hike on the preserve to check out some of its many oaks.
Hagen worked as a forester for Cal Fire for 20 years and as an entomologist with the California Department of Food and Agriculture for nearly 10 years. He is a registered professional forester, a certified arborist, and a qualified tree risk assessor. Steve Barnhart taught biology, botany and ecology at Santa Rosa Junior College for 37 years. He currently serves as Pepperwood's academic director and is a renowned expert on California oaks.
The 3,200-acre Pepperwood Preserve is a community-supported ecological institute that conducts applied research and provides educational programming.
