Last week I visited and re-photographed several coast live oaks that were initially treated with fire mimicry in 2004. You can follow the progress of these treatments in previous posts here and here. Leith Carstarphen of EcoLogic Landscaping has been doing the fire mimicry work under my direction, and as you can see from the photographs he is doing an excellent job on these trees.
It is becoming clear to me that the fire mimicry treatments are showing long-term positive results, while giving very good short-term results as well. Seems we are no longer helpless in saving many of our oaks infected with Sudden Oak Death.
