Scalded Ash Tree

[Billhook]

We were cutting ivy off the trees in the wood which seemed to have been suffocated by it.  On the tall trees we just severed the main stems and eventually it died but remained on the tree

We had a small brash bonfire a couple of years later in the Winter, which must have been over fifty yards away and an ember flew into the dead ivy and the tree went up like a Roman candle.  None of the other trees were affected but I thought that this tree may have had it

However this year all seems well and it seems to have only been singed and has a full green canopy.  I think we were lucky!

Ive an Ash with an almost identical scold. Mine was from a bonfire as well. Three years on and like your pic there is no bark on one side yet still in full leaf.

I would suggest that because the ivy was so dead and dry that it burnt quickly enough not to damage the bark before running out of fuel.  It was quite spectacular at night though!
