It is probably freeze damage from last winter.

I've had some of those on my Mato Buntan at one point when the growth was extremely aggressive. It healed, and then I cut back on the N application and it disappeared. Of course we had occassional freezes too. |

I get that quite often when the tree is flushing and we get a quick freeze. The sap inside the branch freezes & splits the bark. They heal over in time.

Whew......that's good to hear.
Thanks for your insight.
When I first saw the scars on the bark, I though it might be caused by an invisible pest. |

So where in Norcal are you located?
Sometimes the diseases can get through those cracks, so I spray fungicide like copper during the wet winter months. |

It's what happened to my trees after the freeze also. I didn't know what that was until now though. I did suspect the freeze on my avocado tree damage though. A big branch just fell down during the rain storm last week and it apparently broke at one of the "cracks" caused by the freeze. Upon looking a little closer, termites had also gotten in there and were munching away.
