Ant signs of fires close by at some point?

I would look for problems in the canopy such as die back or rotten parts of the stem. Tap them with a stick or the back of a silky.

bleeding canker i believe, very common in mature/over mature hybrid grafted cherries

 

dealt with loads of them down here, does cause heart rot in crown union and can travel down the stem from center out.

Bacterial canker of cherry

 

The causal agent is Pseudomonas syringae pv morsprunorum. Susceptible trees include Prunus avium (wild cherry) and its ornamental and fruiting varieties and other Prunus species including plums, peach and apricot. Symptoms usually consist of scattered shoots which fail to flush in the spring, but sometimes this can affect entire branches or even whole young trees. Close inspection will reveal large areas of dead and dying bark, usually girdling shoots or branches, and an amber coloured gum also exudes from affected areas.

 

During the summer the bacteria which cause the cankering can be found on the cherry leaves causing brown spots. Cracks develop around the brown spots, so the discoloured tissue falls out to leave the so-called ‘shot hole’ symptom. As well as infecting leaves, the bacterium also infects the bark via scars left after leaf fall and through any injuries. It is apparently inactive over winter, but in early spring can grow rapidly in the bark causing cankers.
