Fire mimicry results from Mill Valley and Los Altos, CA

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”.
