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

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.
