Coast live oak in Big Sur cured of stem canker infection using fire mimicry + surgery

18 07 2016

This is exciting news! A coast live oak in Big Sur appears to have been cured of two stem canker infections (possibly Sudden Oak Death) using fire mimicry and surgical methods. Furthermore, no new infections have occurred on this tree. While I’ve reported on the progress of other coast live oaks that have received fire mimicry and surgery (see here, here, and here), this is the first oak that I feel confident has been cured of a stem canker infection!

There is also evidence at the same site that the deep cracks forming in other coast live oaks, cracks that allow infection by stem canker disease, are healing well. And, no new cracks are forming. Published studies have shown that “the presence of unweathered bark in bark furrows, (is) positively correlated with disease (Sudden Oak Death)”. Note in the photo below that the exposed unweathered bark is healing.

Not surprisingly, the canopy health of the coast live oaks at the site is also improving noticeably!
