Poorly Horse Chestnut Trees; update Sept 12th

Before i came on holiday i remember seeing on the news about the damage being caused to the Horse Chestnut trees by caterpillars of the (i think) Coddling moth.

Yesterday at Pensthorpe and today at Sandringham every chestnut tree i have seen is affected,huge trees some of them, with all the leaves shriveled and brown.

I wonder if all parts of the country have been affected?

I will post some pics of the poor trees when i get home .

Oh dear, that is bad news Jan. I remember reading something about some form of virus (I think), which may or may not be the same thing. I will have a search later and see if I can find any links about it.

:thanx: For finding that link Gill but that seems to be something else .This damage is down to caterpillar of some kind ,an alien species of moth i think.
Its unbelievable how badly it has affected the trees,they look dead but apparantly they aren't ,they certainly look a sorry sight.

I'd noticed sorry looking Horse Chestnut trees for some time now. I originally thought that Autumn was coming early.
I've just seen a brown leaved sad looking Horse Chestnut tree, with its conkers easily seen, standing out like bright green dots. The contrast was amazing. I've never seen this before, the conkers and leaves are usually the same bright green colour - it makes spotting them that much harder when the kids are trying to knock them off!

It is a sorry state of affairs. The trees around here seem ok, as far as I can tell. It doesn't seem as if much can be done about it.

:thanks: for the link Jan

It's a great shame Jan and they do look in an awful state.

This is the most likely culprit...

Leaf miner moths can cause massive devastation within woods and forests and certain species such as the Pine and Oak Processionary are considered major pests across Europe and the various government and environmental agencies have large budgets to eradicate and control such species.

We've had this problem in the London/Essex area for 4 or 5 years now. It's such a pity. I have a horse chestnut acroos the road from my house and the council have had to cut it back to barely nothing. :(
