PG&E has provided over 30,000 failure reports to us. In collaboration with the Western Chapter ISA we will sort and analyze the PG&E data and produce species failure profiles.
We are changing the name of our program. It is now called the Western Tree Failure Database.

In recent days some news organizations who are interested in drought related issues have discovered this website. One of them has published an an erroneous interpretation of our data stating that it showed that there is an increase of failures due to the drought. There is no doubt that trees are affected by the drought, but so far, we have not received any reports directly attributing the failure to drought. See "CTFRP Statistics/ Counties and Numbers".

Nomenclature change strikes fear in the heart of database manager!
In the draft edition of Jepson Manual II, the genus name of California native cypress has been changed from Cupressus to Hesperocyparis. Considering that we have over 400 entries for Monterey cypress, we will continue to use Cupressus, at least until Jepson II is in print! Stay tuned.
"Oaks in the Urban Landscape; Selection, Care and Preservation" L. Costello, B. Hagen and K. Jones is now available through the UC ANR catalog. http://anrcatalog.ucdavis.edu It's publication #3518. Chapter 8 is all about structural failures, defects and risk assessment.

LABORATORY ANALYSES OF WOOD DECAY SAMPLES ----- FREE for CTFRP cooperators!
The Forest Pathology and Mycology Laboratory at UC Berkeley has developed a state of the art method that can detect and identify many important wood decay fungi. The lab is now accepting wood samples for analysis. Details are available at:
The following links can be found on the website:
• Shipping Wood Samples to UCB for Analysis
• Tree Sampling Protocol
• Sample Submission Form
This service is available to anyone, but there is a fee (up to $100 per sample). HOWEVER, IF YOU ARE A CONTRIBUTOR TO CTFRP (i.e., YOU HAVE SUBMITTED AT LEAST ONE REPORT) THERE IS NO CHARGE FOR THIS SERVICE! We have been able to secure grant funds to defray the cost of the analysis. All you have to do is indicate on the submission form that you are a contributor (write CTFRP next to your name). Multiple samples can be submitted.
So, if you want to identify a wood decay fungus (either in a standing tree or in one that has failed), this is your opportunity. The test can identify the following genera: Armillaria, Ganoderma, Hericium, Inonotus/Phellinus, Laetiporus, Pleurotus, Schizophyllum, Stereum, Trametes (and more).
It is extremely important to follow the protocol for sampling and shipping. For failed trees, take care to sample from decayed wood at the break. Check the website for complete information on procedures.
Many thanks to Dr. Matteo Garbelotto, UCB, for making this analysis available for CTFRP contributors. Let us know if you have questions or comments.
