New findings on combating sudden oak death
The dark wound on this Portola Valley oak (photographed in 2007) was a late symptom of sudden oak death disease carried by a nearby bay laurel tree on which leaf tips had turned brown, an indicator that the disease is present. After seven years of research on oaks in Santa Cruz County, scientists now have specific recommendations on removing bay laurels from the vicinity of vulnerable oaks.
