Sudden Oak Life by Lee Klinger

Last week I checked up on some oak trees in Glen Ellen, CA to see how they are faring after five years of fire mimicry treatments. I took photos of the oaks and compared them to photos taken five years ago at the same time of year. These are the results. I’m pleased to report that most of the oaks are responding noticeably in terms of canopy density and greenness, and some have improved dramatically. A few of the oaks have a stem canker disease, possibly sudden oak death. These oaks have not shown much response, though it is relevant to note that there are no clear indications of decline in canopy health of these diseased trees in five years. This may even be considered a positive result.
