Surely new growth on old stock still has the adult immunity. After all, even mature trees have new growth every year, if that was affected then they wouldn't be saying trees over 10 years have immunity.

As far as I know, it may be possible to move timber from a site with Chelara, but there are restrictions, and all suspected outbreaks should be reported through the Forestry Commission and any felling, movement etc. done under their direction. Please give as much detail as possible about location, because, 'a dodgy looking ash tree on the M3 between Southampton and Winchester' isn't very helpful. |
Oops! My bits are long gone now. Could I have sent them off somewhere for confirmation or refutation (sp?)? I'm not sure I want anyone coming into my garden possibly carrying the real thing, from their previous inspection site, when what I had might have been something else entirely.

If you cut down a tree it will coppice. Both this growth and the new shoots sent out by a mature tree are the most at risk of Chelara. In the case of the new coppice growth there is a lot of new growth and very little else except for the stub of the stem(s) and the root. There is a far higher proportion of new growth to infect the lower parts of the system, so more risk of the whole thing dying quickly. With a mature tree, there is far more mature wood, and this seems to be less susceptible to the disease, so the tree may not die, or if it does, it may take longer and the ultimate cause of death could be something else like honey fungus.
Initially you tell the FC the site of the suspected infection, with photos if possible. They will send someone out to inspect I think.
If you have had no more trouble with your ash trees, it may not have been Chelara. There are other ash die back diseases, and leaves can be affected by wind, cold or many other things. Watch them next spring and compare any problems with the symptoms of Chelara. If they look the same, I would strongly recommend you report it. |
