We have a very large SC tree in the garden 20/30Mts a lot of the leaves have died and are still hanging to the branches, I think we have SC Blight, which we have to report who too? the Marie?, we have looked after this tree since 2006 when we first bought the land, as you can imagine it was a mess, not been touched for 50/80 yrs, to loose it is going to be heart breaking, it give us a lot of pleasure with it nuts and leaves then in the winter its a magnet for Nuthatches, Treecreepers etc. From what I have read it all has to be taken away and destroyed, so not even any wood for woodworking or heating.

Are you sure it's blight and not just the effects of drought, spectrum? Has the tree got cankers on trunk and branches with orange pustules? Chestnuts can look really sorry for themselves when deprived of water. Here's a link to the INRA site ephytia.inra.fr/fr/C/18514/Forets-Chataignier They don't seem very concerned about it and there's no mention of notifying anyone. They're relying on a hypovirus to naturally combat the fungal disease. |

We have hectares of chataigners and also a few marronaires, most of them have cancer and a lot of them are dieing from it and the heat . It is a result of the changing climate and new tropical diseases arriving with it. We use the wood for heating and the dead trees give life to other creatures too. Plant a new tree ( of a different species) not far away from it, for future generations to enjoy.

I dont think its drought, last year was dryer and warmer than this year, its at the "Bottom" of the garden ie the dampest place, I can see fissures on the trunk but no spores, but its an old tree, the circumference is just over 4Mts, so a lot of bark, as said above its the way the leaves have died back, but not dropped off, will try and get an Arborist to take a look, thanks.

Chancre is hardly a new pathogen....first detected in France in the 1950s  The spread of disease has more to do with the increased export/import of species around the world. |

It's the culmination of many things . Trees grow slowly and die slowly . so the lack of water over many seasons will slowly destroy the trees immune system and it will get diseases. The leaves die due to lack of water. When the trees die .........

I agree , it is an imported disease. Climate change didn't start yesterday either , although nobody listened in the '50 s |

When the trees die ......... Certain trees in certain regions might be struggling to adapt but equally, other species more adapted to those conditions will fill the gaps. Before you start on about biodiversity, a quick stroll around my garden would confirm that half a dozen different species find the conditions congenial enough to seed themselves around. Not necessarily 'natives' (that's such a misleading word!) but perhaps the future natives here. Taking the long view, Nature will decide what thrives and what doesn't. |

Yes , and what I meant was , when the trees die ...... so will we .
It has already been noted that the treeline is moving .
Twenty years or so ago I went to a sylviculture weekend further east of here and was laughed at when suggesting that Douglas were not the best trees to be planting. I had proposed that olives would be better.
Last week discussing climate change with a friend of mine that is a retired bio farmer , he told me that there were already olives being planted in the Lot.
So the sweet chestnuts will die , but desert species will survive , will we?
A while ago I gave up trying to keep species alive that couldn't handle the changes.

Well I don't know about you, but I've never considered myself immortal. So far I've lost one parasol pine, 14 assorted fruit trees and 9 cherries. Most to Cossus cossus and the cherries drowned during a particularly wet winter. I'm still very much alive. A grower in a neighbouring village has planted hectares of Pistachio, Almond and Pecan on the strength of 'climate change'. Let's hope he doesn't get caught out if and when the Gulf stream thingy switches off and we're plunged into a mini Ice age  |

Let's hope he doesn't get caught out if and when the Gulf stream thingy switches off and we're plunged into a mini Ice age I think you misunderstand the impact of the GS switching off. New York, which can get some pretty awful winters but hot summers is on the same latitude as Madrid. Neither have the GS as a (major ) influence on their climate. So, climate change wth a GS shut down that might not favour those new trees, yes. Mini ice age, no. |

It was written tongue in cheek, exile. I must admit I don't spend much time swatting up on all the possible scenarios for the simple reason that most of the info out there is pure guesswork. The doom-mongers can extrapolate all they like, but ultimately, Nature will have the last word (thank goodness).
