In April 2020, UC Cooperative Extension with support from Sonoma State University, Center for Environmental Inquiry hosted a California Oak Health workshop for oak enthusiasts, landowners, natural resource managers, and foresters to discuss issues faced by California’s native oak trees and oak woodlands. Topics included:

  • Conservation of Oregon white oak and Ca black oak woodlands
  • Sudden oak death and other Phytophthora problems in oaks and tanoak
  • Wildfire in tanoak and Ca black oak, blue oak, and interior live oak woodlands
  • A new, non-native beetle threat to valley oaks
