These are from a trip to Marian Bear Memorial Park in San Diego. I saw an article in the newspaper that said that GSOB is here, so I came to check it out. Here's where you can find the article, http://www.signonsandiego.com/news/2010/may/26/borer-beetle-sapping-oaks/

This is a damaged tree. I think it's the same one as in the newspaper article above.







Here's another unhealthy oak tree.

This beetle is not a GSOB, but we see them all the time on infested trees.



These trees are all healthy up on the hillside.









This is a dead, burned tree with some kind of insects in it, but not GSOB.



This is an oak gall. It is the nest of a wasp. It does not harm the tree, it is only a parasite.

This oak tree was right on the edge of the parking lot. It seemed to be infested with GSOB.
