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.

More results from oaks in Fairfax, CA

Slide01

More results of fire mimicry treatments of coast live oaks in Fairfax, CA after nearly two years. Several of these oaks have stem canker infections, probably Sudden Oak Death. Still . . .

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 results from Mill Valley and Los Altos, CA

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.

Portola Valley oaks respond quickly to fire mimicry

Culturally-modified, Native American-era oak showing rapid improvement after fire mimicry.

Last February (2017) I treated and photographed 25 coast live oaks in Portola Valley using fire mimicry practices. A couple days ago I revisited the site and re-photographed the oaks to assess their response. The results show noticeable improvements in the density and greenness of the canopies of most of the treated oaks in just one year. This is becoming a common finding in many of the case studies – that the positive response of the oaks to fire mimicry appears to be rapid.

These results are part of a significant body of evidence showing that oaks and other trees can be brought back to health using fairly simple methods that mimic the effects of fire. If you care to learn more about these methods, please enroll in my upcoming course, “Sudden Oak Life: The Science and Practice of Forest Restoration”.

Surgical procedure for Sudden Oak Death

22 02 2018

Yesterday I worked on several coast live oak trees on a property here in Big Sur, where¬† some of the oaks have been infected with a stem canker infection, probably Sudden Oak Death. The incidence of Sudden Oak Death had increased dramatically here in Big Sur, likely a result of the previous (2017) winter’s extreme wetness. In fact, five severely infected oaks were removed from this same property the previous day. The owner has decide on a new course of action and has employed my services, which involve fire mimicry treatments to his oaks. In addition to these treatments, I performed several surgical procedures to remove the stem canker infections. Here are a series of photos from one such procedure.
