The use of repeat photography to document temporal changes in trees and landscapes was one of the many fine techniques I learned from my PhD advisor Prof. Tom Veblen. He taught me the importance of replicating details such the lens focal length, sky conditions, and time of day. My photos don’t always live up to his standards, but it’s not for lack of trying.
Today I would like to show repeat photographs for several coast live oak trees that have been undergoing fire mimicry treatments for exactly four years. Much of the credit for these results should go to Demetrios Sgouros, Leith Carstarphen, and Daniel Brooke who were among the first tree care specialists to recognize the utility of fire mimicry techniques in helping the many sick oaks here in California.
Readers can judge for themselves whether or not the fire mimicry techniques are helping these oaks, but it sure appears to me and to the owners of the trees that they are making a nice recovery. Note, however, case number 20041129.1 (below) which is a coast live oak that is badly infected with sudden oak death disease. While it is showing some improvement the addition of a new garage next to this tree seems to have had an impact on its recovery. In a previous post I documented the demise of a nearby coast live oak that was also both infected with sudden oak death and impacted by construction. Hopefully this oak will not incur a similar fate.
