Carmel oaks respond to fire mimicry

13 09 2017

Slide1

Three years ago I began treating a grove of mature coast live oaks in Carmel, CA with fire mimicry. Yesterday I checked on their response. As the photos here reveal, most of the oaks show a clear improvement in the leaf density.of their canopies.

I haven’t done a tally on the total number of trees I’ve reported on in the nearly 10 years of hosting this website, but a fair estimate is that it is upwards of 1000 case studies, including oaks, pines, cedars, buckeyes, magnolias, fruit trees, and more. It has been immensely rewarding to witness and report these results, and to demonstrate to all concerned a clear way forward for tending our trees and forests.

Oaks in Fairfax, CA respond to fire mimicry (Part 2)

27 07 2017

Slide01

While on my way to check on the oaks in the previous post, I happened upon another client whose oaks I treated with fire mimicry last September. I stopped to say “Hi” and mentioned that I would return in September for the one-year checkup, but he was anxious to see how his oaks were doing yesterday, so I took the time to¬† re-photogrpah his oaks, Here are the results after 10 months . . .

Oaks in Fairfax, CA respond to fire mimicry (Part 1)

27 07 2017

Slide1

Yesterday, in Fairfax, CA, I examined a number of coast live oaks that I treated with fire mimicry for the first time in July of last year. The first tree I examined was a a large oak that was severely diseased and near death last year. I told the owner that I did not think it could be saved, but he insisted I try. As you can see in the above photo my attempts to save the tree were unsuccessful. The oak came down in a storm this past January.

Fortunately, the owner had me treat his other oaks, some of which are infected with stem canker disease (probably Sudden Oak Death). As you can see in the following photos, all are showing noticeable improvement in just one year. I’m happy to attribute some of this success to the plentiful rains this past winter, however, considering I’ve gotten similar results at the height of the recent drought (see Archives 2013 – 2016), I’m certain that the fire mimicry treatments are assisting in the recovery of these oaks.

Oaks in Piedmont, CA responding to fire mimicry

22 07 2017

Slide01

Two years ago a property owner in Piedmont, CA contacted me about the declining health of their oaks. When I inspected the trees I found a couple of them had stem canker infections (possibly Sudden Oak Death), including the oak pictured above. Most of the oaks were free of infections, but still showed signs of poor health. Now after two treatments using fire mimicry, the oaks, generally, are showing a noticeable improvement in canopy health and density. Note that the photos are not exactly two years apart, but when I re-photograph the oaks again in October I’m betting that the trees will not have lost much, if any, vigor.

Five year results of fire mimicry on oaks in Hillsborough, CA

24 04 2017

Slide02

Last week I inspected several coast live oaks that have received three fire mimicry treatments over the past five years. A couple of these oaks have bleeding stem cankers (probably Sudden Oak Death) that have been treated surgically as well. It will be a few more years before I know if the diseased oaks have recovered, but in the meantime these and the other uninfected oaks appear to be doing fairly well.

A couple of the oaks have lost a few limbs in the storms this past year, but are otherwise healthy. I should add that the wet winter has played some role in the improved canopies, however, results from these same oaks in prior years (2013, 2015) indicate noticeable improvement even under severe drought conditions.

Oaks in Glen Ellen, CA responding to fire mimicry

20 04 2017

Slide21

Seven years ago I began treating a group of coast live oaks with fire mimicry. Several of the oaks are infected with bleeding stem cankers, probably Sudden Oak Death. Despite being diseased, the oaks have shown a steady recovery over the years as can be seen in these photos from 2013, and 2015. On Tuesday I checked on these oaks again and as the photos here show their health, for the most part, continues to improve.

For all the fear-filled hype about diseases and insect pests ravaging our forests, I find very little news about the fact that, whether or not the trees are infected with this disease or infested with that pest or stressed by climate change, sick trees can be brought back to health. I know this from doing the work, treating sick trees, and seeing the results such as these.
