How do I know if my area has been evaluated for sudden oak death?

If you live in a California county that is known to have sudden oak death (SOD), you can check to see if your area has been evaluated for the presence of the pathogen that causes SOD (Phytophthora ramorum) by downloading the free SODMAP Mobile app.  Doing so will allow you to see if trees have […]

I have a very small bay tree that has leaves with P. ramorum symptoms. Should I just remove the tree or take a sample first?

It is always advisable to first have a tree tested before removal to be sure P. ramorum is present.  If you are noticing symptoms in spring, attend a nearby SOD Blitz for information on sampling and lab submissions.  For more information, go to sodblitz.org.

I have an oak in the Bay Area that is oozing liquid from the trunk base. Should I test it for SOD? If so, how?

When will the 2016 SOD Blitz and training sessions be held?

SOD Blitzes include a training session for blitz volunteers on SOD and proper sampling, followed by time in the field  for collecting and marking sample locations. All necessary collection materials are provided to volunteers during the training session for use either the same day of the training or the day after. All samples are to […]

We have bays 100 feet downwind from a coast live oak that seems to be dying of SOD. How do we have our oak tested and how do we determine if the bays are carriers?

Oak testing is routinely done by arborists. It is a rather involved and tedious process that requires a fair amount of finesse and know how as it entails wounding the tree by shaving off the outer layer of bark to collect infected tissue. If you decide to have your oaks tested for SOD, consider going […]
