A coast live oak and a bigleaf maple . . .

29 10 2018

Slide1

The coast live oak above and the bigleaf maple below were treated with fire mimicry last year. I checked on their status recently. Here are the results. Nice to see noticeable improvement in both trees in just a single year!

Coast live oaks in Piedmont, CA after 3 years of fire mimicry . . .

18 10 2018

Slide3

Yesterday I inspected a grove of coast live oaks, some of them Indian-era (pollarded) trees, to assess their response after 3 years of fire mimicry treatments. The photos here show a pretty dramatic increase in canopy greenness and fullness.

Just curious – are the results and information I post here useful to any of you readers? I’m not much of an IT person and would rather focus on working in the woods, but people keep saying that blogs and social media are the best way to share this information. I dunno, I don’t get many visitors to the blog and almost never a comment. Anyone with an opinion on whether or not these results are useful, please feel free to like or comment.

Four-year results of fire mimicry treatments of oaks in Fairfax, CA

30 07 2018

Slide1

Four years ago I began fire mimicry treatments on a grove of coast live oaks in Fairfax, CA. Several of these oaks are infected with stem canker disease, probably Sudden Oak Death. As you can see most of the oaks, as indicated by the size and fullness of their canopies, have responded nicely to the treatments.

Fire mimicry/canker surgery results with oaks in Fairfax, CA

23 07 2018

Slide2

In July of 2016 I began fire mimicry treatments on several coast live oaks in Fairfax, CA. Here are photos showing the response of the oaks after two years. As you can see most of the oaks are showing noticeable improvement in canopy greenness and density.

One of the oaks (Case No. 20160722.4 – see below) had two stem canker infections, probably Sudden Oak Death, that were surgically removed and cauterized in 2016. The last two photos below show the healing of the wounds, both on the same tree. There appears to be no sign of a lingering infection. It’s still too soon to say for sure if the procedure has worked, but the healing results so far are better than expected.

Fire mimicry results from Mill Valley and Los Altos, CA

8 03 2018

Slide1

Slide2

The first two photo sets above are of an oak in Mill Valley, CA that I began treating 5 years ago using fire mimicry. This oak has made significant improvement, as was already documented two years ago here.

The photo sets below are of three coast live oaks, and two coast redwood trees first treated with fire mimicry last year (2017). The first of the series shows a young coast live oak that has lost some leaf density in its canopy. This is an atypical result which may be corrected with further treatments. The other photos sets show an ancient, Native American-era coast live oak that is showing significant improvement in canopy density in just one year. Another mature coast live oak, despite having a major limb removed, is showing slight improvement. And two coast redwood trees are also showing slight improvement in just one year.
