Two years ago the crew and I performed fire mimicry treatments, including a few surgeries for stem canker infections (probably Sudden Oak Death), on a grove of ancient coast live oaks in Aromas, CA. Several of these were pollarded “Ancestor” oaks, remnants of a vast Ohlone acorn orchard. Today I inspected the oaks and found that most of them have responded favorably to the treatments with denser and greener canopies. Here are the before-and-after photos so you can judge for yourself.
