Recovery of oaks following the 2017 Sonoma fires

2 05 2019

Slide3

Yesterday I inspected a grove of oaks that had burned during the 2017 Sonoma fires.  Previous to the fire these oaks had been treated with fire mimicry, which included pruning the lower branches (ladder fuel), clearing away underbrush, removing mosses and lichens from the trunks, fertilizing the soils with compost tea and soil minerals, and applying a limewash to the trunks. During the fires all of the ground vegetation burned, but none of the flames spread into the upper canopies. Thus, all of the oaks survived (as did several nearby homes), and, as the photos show, are doing well after 1.5 years. A caveat – these results are influenced by the spring flush of new leaves, and a better comparison can be made when I visit the site again this October.

These findings represent the combined effects of a ground fire AND fire mimicry treatments on improving the health of California oaks.

Esalen oaks respond to fire mimicry

26 04 2019

Slide4

On April 20, 2012 I gave an Earth Day workshop on at Esalen Institute in Big Sur, CA, where I initiated fire mimicry treatments on several coast live oaks. Since then I have been tending these oaks on a regular basis. Today I inspected the oaks and treated them again. The photos (above and below) show the response after 7 years . . .

This past week I checked on several coast live oaks in Marin County that I’ve been treating for the past 1 to 7 years using fire mimicry techniques. The photos above are of an oak that I’ve treated for the past 7 years. The next two photos are of an oak I’ve treated for the past 5 years. The remainder of the photos are results of oaks I treated last year. I trust you can see the benefits of using fire mimicry in aiding the health of oaks.

Update on stem canker surgical procedures

26 02 2019

Several year ago I began treating a coast live oak in Big Sur, CA with fire mimicry, which included surgical procedures on two stem cankers, presumably Sudden Oak Death infections. A few days ago I checked on the progress of this tree. Below are photos showing that the surgical wounds have healed nicely and there is no sign of further infection.

I also reported, last year, on the methods involved in the surgical procedure for stem canker infections like Sudden Oak Death. Below are photos showing two canker surgeries on the same oak. Close examination of the surgical wounds after one year show no sign of lingering infection (though this is not easily visible in the photos).
