Not forgetting to mention the annual infection of the occluding tissues being the cause of the target like appearance, and lack of successful occlusion.

well yes indeedy.

 

David, I also can't recall seeing failure at a target canker, except for such a canker from Cronartium fusiforme on Pinus taeda.

4 years on and the local LA have removed this cherry posted earlier in this thread. Although the outer canker was seemingly not eating away at a particularly fast rate the actual vitality of the tree was in significant decline. Hopefully will be replanted in the next round of replanting.

That poor tree has been slowly tortured to death.

In the latter shots he is clearly crossing his legs and holding his nuts, before finally screaming.

May his replacement outlive us all.

Huge girdling root likely played a part in both tree response and vitality.
