Last year we treated several coast live oaks, some of them ancestor oaks, with fire mimicry on a property in Felton, CA. They all received compost tea, soil minerals, and limewash, and some of them also had stem canker surgeries. Here are the results, a pretty decent recovery IMO after only one year, under drought conditions …
Indian Canyon Nation, EcoCamp Coyote, and Sudden Oak Life are collaborating on an upcoming 3-day intensive workshop titled “Fire Mimicry and Insights of Traditional Ecological Knowledge” being held at Indian Canyon November 12-14, 2021. This event will feature Kanyon Sayers-Roods (Mutsun Ohlone), Ruth Orta (Him•re-n of Ohlone, Bay Miwok, and Plains Miwok), Ero Gorski and Leo Lauchere (EcoCamp Coyote), and Lee Klinger (Sudden Oak Life). Here are some of the topics we will cover:
• identifying culturally modified trees and landscapes
• the science and practice of fire mimicry
• demonstration of stem canker surgical procedure
• considerations for acorn harvesting
• methods of oak seedling propagation.
This is a rare event and should not be missed by anyone passionate about tending oaks and other native trees. More information and registration for the event are here.
Coast live oak at Indian Canyon tended with fire mimicry since 2019
Last year we treated several coast live oaks and a black oak in Big Sur with a fire mimicry protocol. Here are the results after one year. While the light conditions varied between years, there is clear indication that these oaks are responding positively to the treatments, despite the drought conditions. There is a time-lapse video of the treatment of the black oak (below) on my youtube channel: https://youtu.be/BCK4iQQ6q-0.
See the following link to a youtube time-lapse video showing the treatment sequence of the above oak https://youtu.be/BCK4iQQ6q-0
Ancient Ohlone-tended coast live oak with a severe stem canker disease
I recently inspected four mature coast live oaks in Los Altos, CA that I first treated last year with fire mimicry. All four have stem canker disease (probably Sudden Oak Death), and the largest, a 300+ yrs old Ohlone-tended (pollarded) oak, is severely diseased. Stem canker surgeries involving canker removal with an axe and multi-tool, cauterization of the wound, and poultice application were done on all four oaks.
All four oaks are showing noticeable improvement in canopy health (greenness), and the surgeries, for the most part were successful, although there are small residual infections in two of the oaks that need to be treated. Otherwise, I’m calling this a win after just one year! Of course, I will continue to treat and monitor these oaks in future years.
Last September (2020) I treated 8 mature coast live oaks in Soquel, CA, with fire mimicry. We first pruned and cleared around the oaks, which was documented at the time in this post “Initial stages of fire mimicry in Soquel, CA”. We then spread compost tea and alkaline-rich minerals to the surrounding soils, and applied limewash to the trunks of the oaks. After one (drought) year, all 8 of the oaks are showing improvement in canopy density and lushness. Note that in Case No. 20200927.6 (below), this oak is severely infected with a stem canker disease (probably Sudden Oak Death) but is still showing a slight improvement in canopy health.
Here is a sick coast live oak with a stem canker infection (probably Sudden Oak Death). At that time a surgical procedure was performed to remove and cauterize the canker (see original post here). After one and a half years this oak has made a significant recovery, both in the healing of the surgical wound and in the lushness of the canopy. Note that there is no further bleeding or other symptoms of stem canker infection. More evidence for the efficacy of fire mimicry.
In June of 2018 I discovered two bleeding stem canker infections (possibly Sudden Oak Death) in an old coast live oak in Monterey, CA. I performed fire mimicry treatments on this tree, and surgically removed and cauterized the bleeding stem cankers. Below are photos showing the procedure and as well as the recovery of the wounds and canopy of the oak after three years. Enjoy!
Last year on this date I first treated several ailing coast live oaks with a fire mimicry protocol. To be honest, I was not optimistic about being able to help these oaks, which had been in decline for several years. Still, the owner wanted to try and I’m sure happy that he did. Today I inspected and re-photographed the oaks and, despite the different light conditions, found they have clearly shown improvement in canopy density and lushness. Note that the final oak in this series is UNTREATED.
