A grove of black oaks and coast live oaks in Glen Ellen, CA treated last year with fire mimicry are showing a nice positive response in canopy health, except for one black oak (see photo below) that has lost it’s leaves early and appears distressed. All of these trees survived the recent fires that burned through the area.
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.
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 . . .
