USA is also experiencing ash tree die back. Caused by a non-native insect called the emerald ash borer. Look into whether your trees might be getting attacked by the same insect. If so, there are chemical treatments that are able to save some of the trees, by eliminating the insects; such treatments have to be absorbed through the roots or through the bark to be effective, since the insects are effectively protected from direct sprayed insecticides by the wood once they have bored into it.
@@KStewArb - the one chemical has a trade name of Safari, imidacloprid is another product; as I stated it is absorbed into the tree’s “sap” via the roots or through the bark (through the bark special surfactants are required). The tree in your video was too far gone to be helped, and felling and chipping are the procedure at that stage. The wood should not be transported since that risks further spreading of the insects. EDIT: treatment must be performed on a repeat basis in perpetuity, it’s not a once and done.
Very useful information thankyou. So a tree this far gone say if it was reduced to a point it was alive and then the chemical was used on a repeat basis would it accomplish saving a tree like this once it has been reduced past all the bad dead wood?
@@KStewArb - the use of the chemicals is intended to save the ash trees that still have most of the canopy greening up in spring weather. Once the tree is limited to a few suckers / shooters popping up near the root / trunk base, that’s a tree that isn’t going to be saved. The suckers / shooters might be worth rooting to get new ash trees to develop, and of course you would want to treat them early to prevent EAB damage. And in an area with EAB infestation, what is being recommended here is to treat all ash trees that aren’t going to be cut down, whether they show signs of EAB damage or not. Ash trees that go untreated will eventually succumb to the EAB. The repeat cycle is annual I believe, to fight off the EAB.
Gotcha that makes sense to try and save them whilst they are still showing early signs of the disease. Something I haven't seen in the UK I just presumed there was nothing we could do. I have heard that Sweeden I believe have been trying to hybridise the ash to create a resilient species. Visually Fraxinus Americana 'Autumn Purple' appears to be more resilient over here than Fraxinus excelsior. Thankyou for the information interesting to hear how different countries deal with shared problems

They ate my entire woods
Good job🎉🎉
Thankyou
There's an older map of US affected by this, I'm sure UK and EU are just as affected many years later. en.wikipedia.org/wiki/Emerald_ash_borer
