<DIV>I’ve seen them live for many years with bark signs but no ill
effects. The story I was told at a workshop is that in Quebec where the
disease came a long time ago a percentage of the trees survived. I’d keep it if
it’s healthy.</DIV>

style="FONT-FAMILY: 'Arial','sans-serif'; FONT-SIZE: 10pt">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 (<I>Fagus
grandifolia</I>) 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?<o:p></o:p></SPAN></P>
