Four years of fire mimicry on oaks in Piedmont, CA

21 10 2019

Slide1

in 2015 I began applying fire mimicry treatments to a grove of sick coast live oaks. Yesterday I checked on their status. Here are the photographic comparisons showing that the density and greenness of the oak canopies has increased noticeably after four years of treatments. However, two severely diseased oaks did not respond to the treatments during this period and had to be removed. Fortunately, the remaining oaks appear healthier and the prognosis for recovery is good.

Valley oaks in Walnut Creek, CA respond to fire mimicry

27 05 2019

Slide1

I recently inspected a grove of sick valley oaks that have been treated with fire mimicry for the past two years. The results are very encouraging. Most of the oaks have responded with a noticeable increase in canopy greenness and density. Note that valley oaks do not contract sudden oak death disease, but are still declining in many places. They, too, are generally suffering from a lack of ground fires. Fortunately, these results point to a way forward for improving the health of our great valley oaks using fire mimicry practices.

Saving the redwoods with fire mimicry in Oakland, CA

28 10 2018

Slide1

Two years ago I began treating these coast redwood trees growing in Oakland, CA using a fire mimicry protocol. Here are the results. The redwoods are showing noticeable improvement in canopy size and density after only two years.

Saving the redwoods isn’t just about keeping them from being cut down. It also requires that we tend them, as the California native people did for thousands of years!

Valley oak health improved with fire mimicry care

1 10 2018

Slide1

Two years ago I treated a number of valley oaks in Alamo, CA using a fire mimicry protocol. Here are photos of the oaks showing their response over the past 2 years. As you can see, there has been a notable improvement in the density and size of the leaf canopies both in 2017 and 2018. However, the photos in 2018 were taken a bit earlier than the original photos, which could explain some of the difference in canopy density.

Or maybe I’m just a Photoshop magician! There is a way to find out . . .

Fire mimicry reverses decline in coast redwoods

30 09 2018

Slide12

As I’ve discussedĀ  previously (here), coast redwoods in many areas are showing symptoms of dieback, typically beginning towards the top and progressing downward. Drought and disease have been implicated in the redwood decline, but the true cause remains elusive. I suspect the decline is ultimately related to the altered fire ecology.

In October 2016 I applied fire mimicry treatments to a grove of coast redwoods in Alamo, CA that were in decline. Here are the results after two years.

Positive response of valley oaks in Alamo, CA to fire mimicry

23 10 2017

Slide03

In the previous post I showed the improvement of several redwoods to fire mimicry treatments at a property in Alamo, CA. Today I would like to share the results with the valley oaks at the same location. In both years the oaks have already dropped some of their leaves with the onset of fall. However, this year the oaks, in all but one case, are holding onto their leaves longer, despite it being one of the driest summers on record.

While most of the results shown in this blog are for coast live oaks, it is important to recognize that many other native species, including valley oaks, redwoods, pines, and toyons are showing positive responses to fire mimicry.

Sick redwoods in Alamo, CA respond to fire mimicry

19 10 2017

Slide09

Last year I was contacted by a home owner in Alamo, California about his distressed valley oaks and redwood trees. Yesterday I checked on the status of the trees and today am reporting on the results with the redwoods. In a followup post I will report on the results with the valley oaks.

The redwoods were treated last October with fire mimicry methods, and in one year have made notable improvement in canopy health and size. The photos here tell theĀ  story far better than I can . . .
