Eleven years ago I began treating this grove of oaks in Hillsborough, CA using indigenous-based methods (ie. fire mimicry). These sets of photos show their response after 11 years of care.
These are very significant results in that they show that these methods result in long-term (decade+) sustained recovery of oaks that were in decline.
Oak lovers and tree huggers, please take notice! And, please, thank the native ancestors for showing us the way!
This last oak has been pruned since the initial photo. Note also that the roofline has been altered by construction, obscuring part of the tree. This oak has been infected with a stem canker disease (probably Sudden Oak Death) for the entire period. Despite the disease infection, which has been reduced via fertilization and surgery, this tree remains in relatively good health.
