[CANUFNET] Beech Bark Disease

[Koskinen, Jennifer]

Good day,

To cut or not to cut?  Beech Bark Disease (scale and fungus = canker) is destroying our beech trees.  I have observed cankering on many American Beech (Fagus grandifolia) trees in forests throughout Southern Ontario.  I would definitely recommend a tree (located in/adjacent to a public/residential area) in poor condition with this canker to be removed.  But what about removing trees that appear to be in good condition, minimal to no deadwood in crown, no observed rot on the stem, But with minimal signs of infection on the bark?  Without knowing how long these 'good condition' trees with small patches of infection will survive should we go ahead and remove them to be proactive?  Or retain them and possibly have them die in one or two years becoming a hazard tree?
What do you guys think?  Are there any pathology tree experts out there?
