California oak - sick or not?

[AndrewB]

I have a California live oak (I believe that's the type) next to my house and am not sure if it is sick or not, the bark has looked like this for a long time and the tree has plenty of green, though not as green as neighbors trees. What should I do to help any problems it may have?

I thank you for any advice you can offer.

Oak wilt or maybe pshb?Polyphagous Shot Hole Borers....base of trunk looks not so awesome

It doesn't look too bad to me. Make sure you're not watering it. An oak that size doesn't need any additional water than the rain it gets, even in LA.

The odd bark texture can be from a host of mild fungal infections, usually when its young and there is not really anything that can be done. Typically its not serious. It does look like that tree needs a cable and some more rooting area. Check the ISA website and find an Arborist nearby to have a look. There is a Bartlett Office in San Gabriel that will take good care of you, if your within their footprint. Good luck! and thanks for posting.

Might be some smooth patch but I would also take a closer look for Kretzschmaria or perhaps another Xylariaceae fungus.
