Diseased oaks flourishing after 12 years

Twelve years ago today I initiated fire mimicry treatments on a grove of diseased coast live oaks in Marin County, CA. Since then Leith Carstarphen has been doing the followup work on these trees. Several of these oaks have stem canker infections, probably Sudden Oak Death disease. Two of the oaks in this grove have since died from stem canker infections, but the remainder of the oaks are clearly flourishing.

I should note that, for the above oak, the yellow appearance of the foliage in the recent (right) photo is due to dense clusters of yellowish male flowers.

These thriving oaks stand as testimony to the long-term efficacy of indigenous-based tending techniques (e.g., fire mimicry) in restoring the health of oak forests.
