May I refer you to this excellent article in Guardian / Observer, quoting at some length the Danish forest pathologist. Die-back kills off 90% of Denmark's ash trees. Britain faces a similar threat | World news | The Observer
“ In the state-owned forest in Zealand, north of Copenhagen, forest pathologist Iben Margrete Thomsen says their hope is that around 1% of ash in Denmark may prove resistant and survive.
Passing a stand of balding trees, she points out one that still has a normal leaf cover – "but, of course, we don't know if that is truly a resistant tree or one that will be affected very soon. In the end, though, only the few ash trees which are not susceptible to the fungus will be left. At first it was only the younger trees, and then we started to see it in the older trees too. Now I can see it everywhere. The fungus itself doesn't immediately kill the tree, but if you think of it acting a little like the HIV virus it weakens the immune system and allows some other disease to come in. It is the secondary disease that will finish the tree off.”.... “The rest of Europe wants the UK to act. They are saying 'get a ban' because they have seen what this disease can do. But whether or not it's too late?" She shrugged. "It may be a case of shutting the stable door when the horse has bolted. Time will tell."
We are taking a risk based approach – we are still buying and distributing ash where we have assurances including that all trees are only UK grown. However supplies of infected ash have been imported and have been distributed for planting and our concern is that waiting for the plant health authorities to act may not be sufficient to stop this process quickly enough. Once this has happened it is the landowner – your client – who faces the consequent costs. Plant heath orders are confidential so we have to seek assurances direct from nurseries.
This might shift the balance back in favor of smaller nurseries and we are not adverse to paying for guaranteed quality and good customer service.
