Last year I began fire mimicry treatments on a large grove of ancient coast live oaks in Big Sur. Many of these oaks were culturally modified several hundred years ago by the Esselen Indians. Several of the largest oaks have clear signs of being pollarded, as shown in the photo below.
Culturally modified coast live oak in Big Sur, CA.
Last year I initiated fire mimicry treatments on a grove of coast live oaks in Kentfield, CA. Here are the results . . .
Enjoy!
Four years ago I was contacted by some concerned folks about a very sick oak on their property in Carmel, CA. When I inspected the oak in 2014 I told the owners that I did not think it could be saved, but offered to do what I could to help if they so desired. Fortunately, the owners agreed, and after several years of fire mimicry treatments this coast live oak is showing clear signs of recovery. Note that the current photos show the oak after most of the dead branches have been recently pruned, and the light conditions are different. Still, it is clear to me that this oak is showing significant improvement in canopy density. My lesson here is to trust the property owners and simply do what I can to help the oaks, no matter how futile I think the attempt may be,
Happy Earth Day from Sudden Oak Life! A hopeful message from the oaks . . .
As you may know many of the coast live oaks in Marin County, California are in severe decline. Here are examples of two oaks in Marin County, one in Mill Valley and the other in Larkspur, which were seriously ill upon my initial inspection. The oak in Larkspur was infected with a stem canker disease (probably Sudden Oak Death). Both trees have received fire mimicry treatments for several years, and the owners are pretty happy with the results.
With all the talk of exotic diseases, insect pests, and climate change being the main culprits of forest decline in California and elsewhere, here I show evidence that the real problem is that we are no longer tending our trees. In the words of M. Kat Anderson – “nature misses us”. Solutions are at hand, and they are not difficult to implement.
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 the story far better than I can . . .
Twelve years ago today I initiated fire mimicry treatments on a grove of diseased coast live oaks in Marin County, CA. Since then Leith Carstarphen has been doing the followup work on these trees. Several of these oaks have stem canker infections, probably Sudden Oak Death disease. Two of the oaks in this grove have since died from stem canker infections, but the remainder of the oaks are clearly flourishing.
I should note that, for the above oak, the yellow appearance of the foliage in the recent (right) photo is due to dense clusters of yellowish male flowers.
These thriving oaks stand as testimony to the long-term efficacy of indigenous-based tending techniques (e.g., fire mimicry) in restoring the health of oak forests.
